I know, it's weird. I'm building a new miter saw station and want to make the platforms on either side of the saw height-adjustable so I can tweak them for level. I plan to put T-nuts under the platform supports with set screws in them accessed through a hole in the top surface. The set screws will push against the plywood sub base though and sink in. Anybody know of a metal insert I could mount into the 1/2" plywood to give the setscrews something to push against?

I use flat head screws under the set screws in my router insert plate.

i just use the knock outs from electrical boxes, metal ones. If you happen by a commercial site where they are doing electrical you should be able to find more than you will ever need. Simple little thing that works great.

A penny set into a counterbored hole should do it.

Pennies fit perfectly in a 3/4" recess made with a Forstner bit. Put a little glue in the recess and then push in the penny.

Thanks Cap! Pennies are a great solution.

Pre-1982 pennies are much stronger than the newer copper plated zinc pennies.

Rockler and Lee Valley sells washers for the rare earth magnets. Basically a metal disc with a countersunk hole in the middle for a screw. Gives it a clean look.
