Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Patent Application No. 63 / 044,034, filed June 25, 2020, the entire disclosure of which is incorporated herein by reference.

[0002] FIELD OF THE DISCLOSURE The present disclosure relates generally to a bevel saw configured to make a bevel cut in a workpiece. [Background technology]

[0003] Bevel saws are sometimes utilized to make bevel, or angled, cuts in a workpiece. Conventional bevel saws include conventional bevel guides that allow the bevel cut to have selectively different bevel angles. In many conventional bevel saws, the cutting location where the circular saw blade of the bevel saw enters the workpiece varies depending on the bevel angle relative to the remainder of the bevel saw. As a result, any cutting guide on such conventional bevel saws may accurately represent only the cutting location for a single bevel angle, and / or the bevel saw may include multiple cutting guides, each referenced to a given bevel angle. While effective for making inaccurate cuts, such conventional bevel saws make it difficult to accurately cut a workpiece at a variety of different bevel angles. Therefore, there is a need for an improved bevel saw configured to make bevel cuts in a workpiece. Summary of the Invention [Means for solving the problem]

[0004] Disclosed herein is a bevel saw configured to make a bevel cut in a workpiece. The bevel saw includes a motor including a motor shaft configured to rotate about a shaft rotation axis. The bevel saw also includes an arbor configured to operably mount a circular saw blade to the bevel saw and / or to rotate the circular saw blade in a blade plane and / or about an arbor rotation axis when the arbor receives torque from the motor via rotation of the motor shaft about the shaft rotation axis. The bevel saw further includes a base plate defining an arbor-facing side and an arbor-opposite side. The arbor is operably mounted to the arbor-facing side of the base plate such that the arbor-facing side of the base plate faces the arbor. The bevel saw also includes a bevel guide configured to selectively vary the bevel angle between the blade plane and the arbor-opposite side of the base plate within a range of motion for the bevel cut angle so that the angle of the bevel cut in the workpiece is selectively varied.

[0005] In some examples, the bevel guide includes a guide plate including a first arcuate groove having a first radius of curvature extending from a first origin and a second arcuate groove having a second radius of curvature extending from a second origin spaced from the first origin.

[0006] In some examples, the bevel saw includes a bevel guide mount configured to operably mount the bevel guide to a base plate. The bevel guide mount includes a single bevel guide mount fastener that operably mounts the bevel guide to the base plate. The bevel guide mount also includes a reinforcement structure that defines an opening. The bevel guide mount fastener extends through the opening such that the bevel guide is compressed between the reinforcement structure and the base plate. The bevel guide mount fastener includes a bevel guide mount fastener head that defines a cross-sectional area of ​​the fastener head, and a contact area between the reinforcement structure and the bevel guide is at least 10 times the cross-sectional area of ​​the fastener head.

[0008] 1-18 provide examples of a circular saw 10 and / or method 1000 according to the present disclosure. Elements that serve similar or at least substantially similar purposes are labeled with the same numbers in each of FIGS. 1-18, and these elements may not be discussed in detail herein with reference to each of FIGS. 1-18. Similarly, not all elements are labeled in each of FIGS. 1-18, but their associated reference numbers may be used herein for consistency. Elements, components, and / or features discussed herein with reference to one or more of FIGS. 1-18 may be included in and / or utilized with any of FIGS. 1-18 without departing from the scope of the present disclosure.

[0009] Generally, elements that tend to be included in a particular embodiment are illustrated with solid lines, while elements that are optional are illustrated with dashed lines, although solid line elements may not be essential to all embodiments and may be omitted in some embodiments without departing from the scope of the present disclosure.

[0010] FIG. 1 illustrates an example bevel saw 10 according to the present disclosure and is a schematic front view illustrating a first bevel angle 613, while FIG. 2 is another schematic front view of the bevel saw of FIG. 1 illustrating a second bevel angle 614. FIG. 3 is a schematic side view of the bevel saw of FIGS. 1-2, while FIGS. 4-13 are less schematic illustrations of an example bevel saw 10 according to the present disclosure. More specifically, FIG. 4 illustrates a top profile view of the bevel saw 10, and FIG. 5 illustrates a right side view of the bevel saw 10. FIG. 6 illustrates a left side view of the bevel saw illustrating the bevel saw 10 in a lowered orientation 52, FIG. 7 illustrates a left side view of the bevel saw illustrating the bevel saw 10 in a retracted orientation 54, and FIG. 8 illustrates the left side view of FIG. 7 with several covers removed. Figure 9 is a front view of bevel saw 10 illustrating first bevel angle 613, Figure 10 is a rear view of bevel saw 10, and Figure 11 is a top view of bevel saw 10. Figure 12 is a bottom view of bevel saw 10, and Figure 13 is another front view of bevel saw 10 illustrating second bevel angle 614.

[0011] 1-13 collectively, bevel saw 10 includes a motor 90 including a motor shaft 92 configured to rotate about a shaft rotation axis 94. Bevel saw 10 also includes an arbor 100 configured to receive torque from motor 90 when motor shaft 92 rotates about the shaft rotation axis 94. Receipt of torque may cause arbor 100 to rotate about an arbor rotation axis 102.

[0012] As illustrated by dashed lines in Figures 1-3 and solid lines in Figures 5-10 and 12-13, the bevel saw 10 may also include a circular saw blade 200. When present, the circular saw blade 200 may be operatively attached to the bevel saw via the arbor 100 and / or may be configured for rotational movement therewith. In other words, rotation of the arbor 100, such as about the arbor rotation axis 102, may cause the circular saw blade 200 to rotate, such as in a blade plane 202, as illustrated in Figures 1-3, 5-10, and 12-13. Rotation of the circular saw blade 200 may facilitate cutting of a workpiece 98 with the circular saw blade, as illustrated schematically in Figures 1-3.

[0013] The bevel saw 10 also includes a base plate 304 that defines an arbor-facing side 308 and an arbor-opposite side 312. The arbor 100 is operably mounted to the arbor-facing side 308 such that the arbor-facing side of the base plate faces toward the arbor.

[0014] The bevel saw 10 also includes a bevel guide 600, which may be configured to selectively vary the bevel angle 612 between the blade plane 202 and the arbor-opposite surface 312 of the base plate 304 so as to selectively vary the angle of the bevel cut 99 that the bevel saw is configured to make in the workpiece 98, as illustrated in Figures 1-2. This may include selective variations in the range of motion of the bevel cut angle, such as may be defined between a first bevel angle 613 in Figures 1 and 9 and a second bevel angle 614 in Figures 2 and 13. Examples of the range of motion of the bevel cut angle include an angular range of at least 25 degrees, at least 30 degrees, at least 35 degrees, at least 40 degrees, at least 45 degrees, at most 70 degrees, at most 65 degrees, at most 60 degrees, at most 55 degrees, at most 50 degrees, and / or at most 45 degrees. As discussed in more detail herein, the bevel guide 600 may be operably mounted to the base plate 304 in conjunction with, via, and / or utilizing the bevel guide mount 700.

[0015] The bevel saw 10 may include any suitable type or style of circular saw adapted, configured, designed, and / or constructed to utilize the circular saw blade 200 to cut a workpiece. In other words, the bevel saw 10 may include additional features, which may not be required for all bevel saws 10 according to the present disclosure. Examples of such bevel saws 10 with additional features include a portable bevel saw 12, a plunge saw 30, and / or a track saw 40, as illustrated schematically in FIGS. 1-3 . In some examples, the bevel saw 10 may include structure and / or features from and / or incorporate the functionality of more than one of the above saws. By way of example, and as discussed in more detail herein, a given bevel saw 10 may be a portable bevel saw 12, a plunge saw 30, and / or a track saw 40 and / or incorporate the functionality of the portable bevel saw 12, the plunge saw 30, and / or the track saw 40. Thus, while a bevel saw 10 according to the present disclosure may include one or more features disclosed herein, a bevel saw 10 need not include all of the features disclosed herein.

[0016] The motor 90 may include any suitable structure capable of providing motive power for rotation of the motor shaft 92 and / or for operation of the circular saw blade 200. Examples of the motor 90 include an electric motor, an AC electric motor, a DC electric motor, a brushless DC motor, a variable speed motor, and / or a single speed motor.

[0017] As illustrated by dashed lines in Figures 1-3 and solid lines in Figures 4, 6-8, and 10-11, bevel saw 10 may include a gripping area 60 configured to be grasped and / or held by a user while operating the bevel saw. Gripping area 60, when present, may be referred to herein as and / or may be a handle or handgrip.

[0018] As illustrated by dashed lines in Figures 1-3 and solid lines in Figures 4 and 6-8, bevel saw 10 may also include at least one switch 65. When present, switch 65 may be configured to be selectively activated by a user of the bevel saw, such as to enable and / or permit the provision of current to at least one other component of the bevel saw and / or to permit power drive of that at least one other component of the bevel saw. By way of example, selective activation of switch 65 may be utilized to enable operation of the bevel saw's motor controller, selectively apply current to motor 90, enable the motor controller to selectively apply current to the motor, and / or permit or direct the motor to provide motive power for rotation of the motor shaft.

[0019] In some examples, the current may be utilized to power or directly power at least one other component of the bevel saw, such as the motor 90. In some such examples, the current may also be referred to herein as a power signal. In some examples, the current may be an electrical data signal sent to at least one other component of the bevel saw, such as a motor controller for the bevel saw. In some such examples, the current may also be referred to herein as a data signal and / or an electrical data signal. Examples of switch 65 include an electrical switch, a normally open electrical switch, a momentary electrical switch, and / or a latching momentary electrical switch.

[0020] Bevel saw 10 may include any suitable power source and corresponding power structure for powering motor 90. Examples of power structures include power supply structure 70, such as power cord 72, and / or battery 74, as illustrated in FIGS.

[0021] As also illustrated by dashed lines in FIGS. 1-3 and solid lines in FIGS. 4-13, the bevel saw 10 may include a blade guard 80. The blade guard 80, when present, may be configured to cover, store, and / or contain at least a region of the circular saw blade 200, such as to prevent or reduce the likelihood of contact between a user and the circular saw blade. In some examples of the bevel saw 10, the blade guard 80 may include a retractable region. The retractable region may be configured to fold, rotate, and / or otherwise store when the bevel saw is utilized to cut a workpiece. The retractable region may additionally or alternatively be referred to as a storage region and / or a folding region.

[0022] In some examples, as discussed, the bevel saw 10 may include and / or be a plunge saw 30. In examples of bevel saws 10 that are or include a plunge saw 30, the arbor 100 may be configured to move relative to the base plate 304, such as to selectively vary the regions 320 of the circular saw blade 200 that protrude from the base plate 304 and / or to selectively vary the cutting depth of the bevel saw. The arbor 100 may be operably mounted to the arbor-facing side 308 of the base plate 304 with, through, and / or utilizing a base plate pivot 316, as illustrated in dashed lines in FIGS. 1-3 and solid lines in FIGS. 6-8 and 11-12. In such an example, the arbor 100 and base plate 304 may be configured to rotate relative to one another about the base plate pivot 316, such as to selectively vary the area 320 of the circular saw blade 200 extending on the arbor-opposing side 312 of the base plate, as perhaps best illustrated by translation from the configuration illustrated in FIG. 4 illustrating a fully lowered orientation 52 to the configuration illustrated in FIG. 5 illustrating a fully retracted orientation 54.

[0023] In other words, the arbor 100 may be configured to pivot relative to the base plate 304 through a range of relative orientations or angles, which may be bounded by a lowered orientation and a retracted orientation. For each relative orientation in this range of relative orientations, the circular saw blade 200 may extend on the arbor opposite surface 312 by a corresponding amount, thereby providing a corresponding maximum cutting depth for the bevel saw.

[0024] In some examples, as discussed, the bevel saw 10 may include and / or be a track saw 40. In examples of bevel saws 10 that are or include a track saw 40, the base plate 304 may include rib-receiving channels 324, which may be configured to receive the raised elongated ribs 44 of the track 42, as perhaps best illustrated in FIGS. 1-2 . The track 42, sometimes referred to herein as an elongated track 42, may be formed from one or more elongated track segments or portions 46, which may be operably attached relative to one another to define any suitable track length. During operation of the track saw 40, the track 42 may be operably attached or fastened to the workpiece 98 such that the edges of the track correspond to the desired cut line for the track saw. The track saw may then be positioned relative to the track so that the raised elongated ribs 44 are positioned within the rib-receiving channels 324, and the track saw may then be translated along at least a portion of the length of the elongated track, thereby producing a straight cut along the desired cutting line.

[0025] 1-3 schematically illustrate an example bevel saw 10 including a bevel guide 600 according to the present disclosure, and FIGS. 13-15 are less-schematic illustrations of example components of the bevel saw 10 highlighting the example bevel guide 600 according to the present disclosure. As illustrated schematically in FIGS. 1-3 and less-schematically in FIGS. 14-15, the bevel guide 600 may include a guide plate 622. The guide plate 622 may include a first arcuate groove 628 and a second arcuate groove 640. As illustrated in FIGS. 1-3 and 15, the first arcuate groove 628 may have a first radius of curvature 632, and the first radius of curvature 632 may extend from a first origin 636. Similarly, the second arcuate groove 640 may have a second radius of curvature 644, and the second radius of curvature 644 may extend from a second origin 648. The second origin 648 is spaced apart from the first origin 636. As a result, the first arcuate groove 628 and the second arcuate groove 640 may sometimes be referred to herein as and / or may be non-concentric arcuate grooves.

[0026] The first radius of curvature and the second radius of curvature may both be greater than zero or may have a non-zero magnitude. Additionally, the first radius of curvature 632 may differ from the second radius of curvature 644. By way of example, the ratio of the first radius of curvature to the second radius of curvature may be at least 1.25, at least 1.5, at least 1.75, at least 2, at least 2.25, at least 2.5, at least 2.75, at least 3, at least 3.25, at least 3.5, at least 3.75, at least 4, at most 6, at most 5.5, at most 5, at most 4.5, at most 4, at most 3.5, and / or at most 3. The first radius of curvature and / or the second radius of curvature may have any suitable magnitude and / or be defined. Examples of magnitudes of the first radius of curvature include at least 25 mm, at least 30 mm, at least 35 mm, at least 40 mm, at least 45 mm, at least 50 mm, at least 55 mm, at least 60 mm, at least 65 mm, at least 70 mm, at least 75 mm, at least 80 mm, at least 85 mm, at least 90 mm, at least 95 mm, at least 100 mm, at most 200 mm, at most 175 mm, at most 150 mm, at most 125 mm, at most 100 mm, and / or at most 75 mm.

[0027] The second origin may be spaced apart from the first origin by any suitable amount. By way of example, the distance between the first origin and the second origin may be at least a threshold fraction of the first radius of curvature. Examples of threshold fractions of the first radius of curvature include at least 1%, at least 2.5%, at least 5%, at least 7.5%, at least 10%, at least 12.5%, at most 50%, at most 40%, at most 30%, at most 20%, at most 15%, and / or at most 10%.

[0028] 1-3 and 14-15, in some examples, the bevel guide 600 may include multiple pins 652, including at least a first pin 656 and a second pin 660. The first pin 656 may be configured to operably translate along the first arcuate groove 628 as the bevel angle 612 selectively varies throughout the bevel cutting angle's range of motion. Similarly, the second pin 660 may be configured to operably translate along the second arcuate groove 640 as the bevel angle selectively varies throughout the bevel cutting angle's range of motion.

[0029] The arbor of the bevel saw may be operably attached to one of the guide plate 622 and the pin 652, and the base plate of the bevel saw may be operably attached to the other of the guide plate and the pin 652. Additionally, multiple pins and guide plates may together attach the arbor to the base plate. With this in mind, the guide plate 622 and the pin 652 may be utilized together to position or locate the base plate and arbor, the motor, and / or the circular saw blade relative to one another while the bevel angle 612 is changed.

[0030] 1-3 and 14-15 , the bevel guide 600 may include multiple bushings 670, such as a first bushing 672 and a second bushing 674. When present, the first bushing 672 may extend about at least a region of the first pin 656 that extends within the first arcuate groove 628. In some examples, the first bushing may extend between the first pin and the first arcuate groove and / or may be configured to separate or maintain a spaced apart relationship between the first pin and the first arcuate groove. In some examples, the first bushing may be configured to rotate about the first pin 656 and / or within the first arcuate groove 628. Similarly, the second bushing 674, when present, may extend about at least a region of the second pin 660 that extends within the second arcuate groove 640. In some examples, the second bushing may extend between the second pin and the second arcuate groove and / or may be configured to separate or maintain a spaced apart relationship between the second pin and the second arcuate groove. In some examples, the second bushing may be configured to rotate about the second pin 660 and / or within the second arcuate groove 640. Such a configuration may reduce frictional forces and / or wear within the bevel guide 600 and / or may make it easier for a user to adjust the bevel saw through the entire range of motion of the bevel cutting angle.

[0031] 3, the bevel saw may include multiple bevel guides 600, including at least a leading bevel guide 604 and a trailing bevel guide 608. Such a configuration may increase the stiffness and / or precision of the bevel guides and / or reduce the likelihood of unexpected changes in angle 612. In some such configurations, the bevel saw 10 may also include a leading bevel guide mount 702, which may be configured to operably mount the leading bevel guide 604 to the leading region 305 of the base plate 304, and a trailing bevel guide mount 704, which may be configured to operably mount the trailing bevel guide 608 to the trailing region 306 of the base plate.

[0032] Leading bevel guide 604 and trailing bevel guide 608 may include similar structures, such as those discussed herein with reference to bevel guide 600. By way of example, leading bevel guide 604 may include a leading guide plate 623 including a first leading arcuate groove 629 and a second leading arcuate groove 641. First leading arcuate groove 629 may have a first leading radius of curvature 633 that may extend from a first leading origin 637. Additionally, second leading arcuate groove 641 may have a second leading radius of curvature 645 that may extend from a second leading origin 649. Second leading origin 649 may be spaced apart from first leading origin 637.

[0033] Similarly, the trailing bevel guide 608 may include a trailing guide plate 625 that may include a first trailing arcuate groove 630 and a second trailing arcuate groove 642. The first trailing arcuate groove 630 may have a first trailing radius of curvature 634 that may extend from a first trailing origin 638. Additionally, the second trailing arcuate groove 642 may have a second trailing radius of curvature 646 that may extend from a second trailing origin 650. The second trailing origin 650 may be spaced apart from the first trailing origin 638.

[0034] Leading bevel guide 604 and trailing bevel guide 608 may have any suitable configuration and / or relative orientation. By way of example, leading guide plate 623 may have and / or define a leading planar guide plate surface 624, and first leading arcuate groove 629 and / or second leading arcuate groove 641 may be defined therein. Similarly, trailing guide plate 625 may have and / or define a trailing planar guide plate surface 626, and first trailing arcuate groove 630 and / or second trailing arcuate groove 642 may be defined therein. In such a configuration, the trailing planar guide plate surface may face toward the leading planar guide plate surface.

[0035] As another example, leading guide plate 623 may extend parallel, or at least substantially parallel, to trailing guide plate 625. As yet another example, first leading radius of curvature 633 may be equal to, or at least substantially equal to, first trailing radius of curvature 634. As another example, second leading radius of curvature 645 may be equal to, or at least substantially equal to, second trailing radius of curvature 646. As yet another example, first leading origin 637 may be aligned with first trailing origin 638 along first alignment axis 639. Additionally or alternatively, second leading origin 649 may be aligned with second trailing origin 650 along second alignment axis 651. The second alignment axis may be parallel, or at least substantially parallel, to the first alignment axis.

[0036] As illustrated by dashed lines in Figures 1-3 and solid lines in Figures 4-13, the bevel guide 600 may include a bevel lock 680. When present, the bevel lock 680 may be configured to selectively maintain the bevel guide 600 at a selected bevel angle 612 within the bevel cutting angle's range of motion. Examples of the bevel lock 680 include a cam, a cam lock, a set screw, a thumb screw, and / or a selectively actuated friction interface.

[0037] A bevel saw 10 including a bevel guide 600 according to the present disclosure may provide distinct advantages over conventional bevel saws that do not include the bevel guide 600. By way of example, the bevel guide 600, including the configuration and / or relative orientation of its first arcuate groove 628 and / or second arcuate groove 640, may maintain an accurate, precise, and repeatable bevel angle 612 throughout the entire range of motion of the bevel cut angle and / or with minimal hysteresis in the bevel angle. This may be in contrast to conventional bevel saws, where structures utilized to vary the bevel angle may be inaccurate, imprecise, and / or may exhibit significant hysteresis.

[0038] As another example, the bevel guide 600, including the configuration and / or relative orientation of its first arcuate groove 628 and / or second arcuate groove 640, may allow the bevel saw 10 to maintain a constant, or at least substantially constant, location where the circular saw blade 200 intersects with the arbor-facing surface 312 of the base plate 304. An example of such a location is illustrated in FIGS. 1-2 and 13 as location 620. This may include maintaining location 620 constant, or at least substantially constant, as the angle 612 varies throughout the bevel cutting angle's range of motion. In other words, the bevel saw 10 may be configured such that the location of the blade plane 202 within the arbor-facing side defined by the arbor-facing surface 312 of the base plate 304 may change by less than a threshold amount of variation and / or distance as the bevel angle 612 varies throughout the bevel cutting angle's range of motion. Examples of threshold variation amounts and / or distances include 0 millimeters (mm), at least 0.01 millimeters (mm), at least 0.05 mm, at least 0.1 mm, at least 0.15 mm, at least 0.2 mm, at most 5 mm, at most 4 mm, at most 3 mm, at most 2 mm, at most 1 mm, at most 0.5 mm, at most 0.25 mm, at most 0.1 mm, at most 0.05 mm, and / or at most 0.01 mm. This may be in contrast to conventional bevel saws, where the location of the blade plane can vary greatly depending on the bevel angle.

[0039] 16-18 are less schematic illustrations of example components of bevel saw 10, highlighting an example bevel guide mount 700 according to the present disclosure. More specifically, FIG. 16 illustrates an exploded view of base plate 304 and bevel guide mount 700 of bevel saw 10, and FIG. 17 is a bottom view of the base plate of FIG. 16. FIG. 18 is a cross-sectional view of the base plate of FIGS. 16-17 taken along line 18-18 of FIG. 17.

[0040] The bevel saw 10 of Figures 16-18 may include and / or be a more detailed and / or different illustration, view, and / or example of the bevel saw 10 of Figures 1-15. Consequently, any structure, function, and / or feature disclosed herein with reference to the bevel saw 10 of Figures 16-18 may be included in and / or utilized with the bevel saw 10 of Figures 1-15 (although not necessarily in all embodiments) without departing from the scope of the present disclosure. Similarly, any structure, function, and / or feature disclosed herein with reference to the bevel saw 10 of Figures 1-15 may be included in and / or utilized with the bevel saw 10 of Figures 16-18 (although not necessarily in all embodiments) without departing from the scope of the present disclosure.

[0041] Bevel guide mount 700 may include bevel guide mount fasteners 720, and in some examples, may include only a single bevel guide mount fastener that operably attaches the bevel guide to the base plate. Bevel guide mount 700 may also include a reinforcement structure 732 that defines an opening 736. Bevel guide mount fastener 720 may extend through opening 736 when the bevel guide is operably attached to the base plate via the bevel guide mount. In such a configuration, the bevel guide is sometimes referred to as being compressed between the reinforcement structure and the base plate.

[0042] The bevel guide mount fastener 720 may include a bevel guide mount fastener head 724 that defines a cross-sectional area of ​​the fastener head. The contact area between the reinforcing structure 732 and the bevel guide 600 may be at least a threshold multiple of the cross-sectional area of ​​the fastener head. Such a configuration may increase the compressive force that can be applied by the bevel guide mount fastener 720 to the bevel guide 600 without damaging the bevel guide. Additionally or alternatively, such a configuration may increase the holding force that the bevel guide mount 700 applies to the bevel guide 600 and / or reduce the likelihood of the bevel guide mount fastener loosening. Examples of threshold multiples include threshold multiples of at least 4 times, at least 6 times, at least 8 times, at least 10 times, at least 15 times, at most 30 times, at most 20 times, at most 15 times, and / or at most 10 times the cross-sectional area of ​​the fastener head.

[0043] As perhaps best illustrated in FIG. 18 , the reinforcing structure 732 may extend on opposite sides of the bevel guide mount fastener 720 such that the reinforcing structure defines at least two spaced-apart contact areas 738 with the bevel guide 600. The opening 736 in the reinforcing structure 732 may extend through a central region, or midpoint, of the reinforcing structure 732, and the contact areas 738 may extend equal, or at least substantially equal, distances from the opening 736 and / or from the bevel guide mount fastener 720. As also illustrated in FIG. 18 , the reinforcing structure 732 may not contact the bevel guide 600 in a region 740 immediately below the bevel guide mount fastener head 724. Such a configuration may allow the bevel guide mount 700 to resist twisting and / or rotation between the bevel guide 600 and the base plate 304, such as about the elongated axis of the bevel guide mount fastener.

[0044] In some examples, the base plate 304 and / or the reinforcement structure 732 may have and / or define a high surface area region 744 that contacts the bevel guide. The presence of the high surface area region 744 may reduce the likelihood of relative movement between the bevel guide and the base plate when the bevel guide mount 700 operably attaches the bevel guide 600 to the base plate 304. Examples of the high surface area region 744 include a ribbed region, a serrated region, a roughened region, and / or a plurality of protrusions.

Multiple entities listed with "and / or" should be construed in the same manner, i.e., "one or more" of the entities so combined. Other entities other than the entity specifically identified by the "and / or" phrase may optionally be present, whether related to the specifically identified entity or not. Thus, as a non-limiting example, when used with open-ended language such as "comprising," a reference to "A and / or B" may, in one embodiment, refer to A only (optionally including entities other than B), in another embodiment, B only (optionally including entities other than A), or in yet another embodiment, both A and B (optionally including other entities). These entities may refer to elements, acts, structures, steps, operations, values, etc.

This definition also allows for entities other than those specifically identified in the list of entities to which the phrase "at least one" refers, to be optionally present, whether or not related to the specifically identified entities. Thus, as a non-limiting example, "at least one of A and B" (or, equivalently, "at least one of A or B," or, equivalently, "at least one of A and / or B") may refer, in some embodiments, to at least one, optionally more than one, A, in the absence of B (and optionally including entities other than B); in other embodiments, to at least one, optionally more than one, B, in the absence of A (and optionally including entities other than A); and in still other embodiments, to at least one, optionally more than one, A, and at least one, optionally more than one, B (and optionally including other entities). In other words, the phrases "at least one," "one or more," and "and / or" are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions "at least one of A, B, and C," "at least one of A, B, or C," "one or more of A, B, and C," "one or more of A, B, or C," and "A, B, and / or C" may mean A only, B only, C only, A and B together, A and C together, B and C together, A, B, and C together, and optionally any of the above in combination with at least one other entity.

It is within the scope of this disclosure that elements, components, and / or other listed subject matter listed as adapted to perform a particular function may additionally or alternatively be described as being configured to perform that function, and vice versa.

[0049] As used herein, the phrases "for example," "for example," and / or simply the term "example," when used in reference to one or more components, features, details, structures, embodiments, and / or methods according to the present disclosure, are intended to convey that the described components, features, details, structures, embodiments, and / or methods are exemplary, non-exclusive examples of the components, features, details, structures, embodiments, and / or methods according to the present disclosure. Thus, the described components, features, details, structures, embodiments, and / or methods are not intended to be limiting, necessary, or exclusive / exhaustive, and other components, features, details, structures, embodiments, and / or methods, including structurally and / or functionally similar and / or equivalent components, features, details, structures, embodiments, and / or methods, are also within the scope of the present disclosure.

[0050] As used herein, "at least substantially," when modifying a degree or relationship, may include not only the "substantial" degree or relationship listed, but also the entire range of the listed degree or relationship. A substantial amount of the listed degree or relationship may include at least 75% of the listed degree or relationship.
