Hello,I am in the process of building a 5x10' water plasma table, I've been following as many builds as I can, however I could really use some help on finalising a few questions about the gantry...
Dimensions of the end plates, I plan to copy others with a piece of 1" aluminum on each end of a 3"x3" (thinking 3/16th) square tube. I'd like to keep the gantry as small as possible, I have a piece of 1" x 12" x 12' aluminum to work with, I realize 12" is a little narrow, but the price is right.

How high above the table would you recommend? I am thinking about 8" from the bottom of the square tube to the slats of the table.

Thanks for your time!
