Drawer Squaring Frame
Chamfer for chip clearance -
Screw or clamp frame to bench
I make a lot of drawers in my shop and got tired of fiddling with squares and pinch rods to square up the boxes during assembly. I decided to build a squaring frame to make the job go much quicker. It's really nothing more than an accurate 90° corner against which 1 can press the assembled drawer parts to square them up.
For quick, strong construction, I made the frame from six 2" x 18" strips of Vr'-thickBaltic birch plywood, creating the corner joint by simply overlapping alternating pieces. I glued the layers together, clamping the two legs perfectly square to each other before driving in finish nails along the legs and at the corner. After the glue dried, I chamfered the bottom of the inner edge to create clearance for dust and chips. Then I drilled screw holes
for attaching the unit to my bench.
For assembly, 1 screw the frame to my bench, then push a glued-up drawer corner against it. Because the frame is screwed fast, I can tap on a drawer corner with my mallet to bring it into square before installing screws, nails or other fasteners. If necessary, drawers can be clamped against the frame to dry overnight.

Magnetic Stop-block for the Table Saw
When crosscutting a series of short pieces from a longer board using the table saw's miter gauge, it's dangerous to use the rip fence as a stop. The freed pieces can get jammed between the blade and fence, causing kickback. To prevent this, the usual approach is to clamp a wide "standoff" block to the rip fence to serve as a stop-block. That way, there's a recess between the blade and fence for the offcuts to go.
The problem with this approach is that even with a wide standoff block, the recess can fill up pretty quickly, forcing you to shut off the saw to clean away the accumulation of offcuts. To eliminate this problem, I use my dial indicator's magnetic base as a stop-block. I initially position the base with it pressed against my rip fence, which squares it to the end of the workpiece. After magnetically locking the base to the table, I slide the fence away so there's nothing restricting the offcuts.
One glitch I encountered was that the rough powder-coat paint job on my magnetic base caused balky forward movement of the workpiece. To fix that, I simply applied a short section of self-stick measuring tape left over from a jig project. PW
