Abstract
A clamp to make a straight edge on a working board has a base with a lower surface to slide on a table saw and a main wall that extends upward from the base. A lower support extends outwardly from the main wall in opposite directions, and two upper supports extend outwardly from the main wall in opposite directions to define channels, wherein a reference board is placed in one channel and the working board in the other channel. A shim arm is pivotally mounted to and extends along the base. A shim support pad is mounted at the free end of the arm and its upper surface is in the same plane as the upper surface of the base. The shim arm swings out from the base so that the pad forms a support on which the working board rests to effectively increase the width of the base.
Claims13
A clamp to support a working board whose edge is to be squared by moving it along the table of a saw into a saw blade, said clamp comprising:
- a base having a lower surface that is to slide on the saw table;
- a main support wall extending vertically from said base;
- a first support wall extending horizontally from and transverse to said main support wall to define a channel between the upper surface of said base and the lower surface of said first support wall to accept an edge of the working board on the upper surface of said base;
- a thumbscrew extending downwardly from said first support wall to engage the working board upper surface;
- and
- a shim support pivotally mounted to said base to swing outwardly of said base and provide support for the working board lower surface, wherein said shim support has an upper surface that forms a support surface that is substantially coplanar with the upper surface of said base, said shim support pivoting in a plane that is substantially coplanar or substantially parallel to the upper surface of said base.
