Jim,

Doggone it! Just when I was getting comfortable you obsoleted my fab table. :-) Today I used my flat table to fixture 3 different assemblies. Each required tacking a dozen or more clips to the table and cleaning them off when done.

I need a longer table anyway so I may steal some of your design.

I am thinking maybe narrowing up the "slots" and raising the top channels a little higher off the beam so that I could slide fabricated t-nuts in from the sides. What do you think?

Another advantage to your table is easy squaring. You have so many square reference points. Brilliant! As for the rare need for a continuous top, nothing stops you from throwing a sheet of 1/4" plate up there for a special job.

What kind of clamps are you using with that table?
