You don’t avoid cutting part of the jig (start and stop). You should be using 3/4in hardwood on the frame, and most dados are usually 1/4in or less deep, so there will still be plenty of frame left after “clearing” the ends. FWIW, I used 3/4in ply on the rest of that jig as well. What that means is that I have to set my 1/2in router bit a little more proud depending on how deep my dado will be.
Picked up the needed 1/4-20 flat head screws at HD. Geez I hate having to buy screws 4-at-a-time! I needed 32 of them for my casters and was prepared to buy a box of 50, but NO! I had to spend over $10 just to get 32 of them! Grrr…
No picks today, as I am measuring and marking where my non-dado’d joints are, so that I can pre-drill and countersink the holes. Slow and tedious so I have the radio nice and loud… 8-)
