I built a table for my 17" Jet. It had a round table, I built a rectangle the same width as the round table.
The crank handle to raise is just as accessible as it was before, I've seen many DP tables that require an an adapter or relocate to use the crank. You have push button, so it's not a thing with you.
14" x 24" and I've never needed it to be bigger.
I'm probly going to let you down but, I swear I won't keep you down. John Hiatt
