Was able to get back at this today:
UntitledSquared up the support tubes with this makeshift jig and tacked the first two top tubes in place
Tack
UntitledFit Check.
UntitledSpaced out the rest of the top tubes and welded those in place on the top side.
UntitledChecked the spacing on the last tube. This is the piece I am going to keep removable and weld tabs so it can be positioned as shown and also butt up against the end tube.
Next I flipped it over and completed all the welds on the bottom side.
UntitledOk..
UntitledBetter...
UntitledAlot better!
UntitledStill fits, however the support tubes got distorted during the welding.
UntitledUntitledGuess I get to learn how to flame straighten! Turns out the support tubes were 11 gauge. I had asked for 14 from the steel supply place. Not complaining as that is what I initially wanted, and the distortion would probably have been more significant with 14ga.
This is alot more fun than buying a table from Harbor Freight.
