a second lock adapted to positioned in the guide recess of the woodworking support, the second lock having an unlocked arrangement having a third width and a locked arrangement having a fourth width, the fourth width being greater than the third width; and
a mechanical actuator having an operator input positionable in a first position wherein the first lock is in the unlocked arrangement having the first width and the second lock is in the unlocked arrangement having the third width and a second position wherein the first lock is in the locked arrangement having the second width and the second lock is in the locked arrangement having the fourth width;
wherein the mechanical actuator includes a base, a first coupler coupling the first lock to the base at a first location, a second coupler coupling the second lock to the base at a second location, and a cam member rotatably coupled to the base at a third location, the third location being between the first location and the second location.
2. The accessory of claim 1 , wherein the mechanical actuator simultaneously actuates each of the first lock from the unlocked arrangement to the locked arrangement and the second lock from the unlocked arrangement to the locked arrangement when the actuator is moved from the first position to the second position.
3. The accessory of claim 2 wherein the mechanical actuator simultaneously actuates each of the first lock from the locked arrangement to the unlocked arrangement and the second lock from the locked arrangement to the unlocked arrangement when the actuator is moved from the second position to the first position.
4. The accessory of claim 1 , wherein the mechanical actuator simultaneously actuates each of the first lock from the locked arrangement to the unlocked arrangement and the second lock from the locked arrangement to the unlocked arrangement when the actuator is moved from the second position to the first position.
5. The accessory of claim 1 , wherein the cam actuates each of the first lock from the unlocked arrangement to the locked arrangement and the second lock from the unlocked arrangement to the locked arrangement when the actuator is moved from the first position to the second position.
6. The accessory of claim 1 , wherein the base is supported by the body and is vertically raised relative to the body when the first lock is in the locked arrangement and the second lock is in the locked arrangement.
7. The accessory of claim 6 , wherein a movement of the cam member vertically raises the base relative to the body.
8. The accessory of claim 7 , wherein the cam member contacts the body when the first lock is in the locked arrangement and the second lock is in the locked arrangement.
9. The accessory of claim 6 , wherein the first lock includes a first slider and a second slider separated from the first slider by a first amount when the first lock is in the unlocked arrangement having the first width and by a second amount when the first lock is in the locked arrangement having a second width.
10. The accessory of claim 9 , wherein the first coupler includes a first portion positioned between the first slider and the second slider, the first portion of the first coupler having a first vertical position when the first lock is in the unlocked arrangement and a second vertical position when the first lock is in the locked arrangement, the second vertical position being closer to the body than the first vertical position.
11. The accessory of claim 10 , wherein the first coupler is adjustable to set a value for the second amount.
12. The accessory of claim 11 , wherein the first lock and the second lock are part of an integral slider.
13. The accessory of claim 1 , wherein the body includes a first elongated slot and a second elongated slot, the first coupler passing through the first elongated slot of the body and having a first end coupled to the first lock and a second end coupled to the base of the mechanical actuator and the second coupler passing through the second elongated slot of the body and having a first end coupled to the second lock and a second end coupled to the base of the mechanical actuator.
14. The accessory of claim 13 , wherein the body is moveable relative to the base when the first lock is in the unlocked arrangement and the second lock is in the unlocked arrangement and is fixed relative to the base when the first lock is in the locked arrangement and the second lock is in the locked arrangement.
15. The accessory of claim 1 , wherein the accessory includes a featherboard.
