I used 16" x  24" 3/4 MDF. It is best if you seal it with paint or some sealer.
I set the edge of the clamps flush to edge of the board to get the rails parallel.
Mark the holes & drill. I used a 3/32 drill bit.
I put the drive & breakout board on the back end. You can put them on later.
There ia a drawing at the bottom for table mounting / setup

Most of the parts are acrylic, DO NOT OVERTIGHTEN SCREWS.
This will not be machining titanium.
You will either get it, or you won't.

I used 1/4-20 all-thread / threaded rod cut to about 4.75".
Use some something for a spacer to make sure the top is the same height all the way around.
I had a piece of 3" PVC pipe I used.
Otherwise you can have a warped table top.
