Well i finally got round to teaching myself to weld, used up a whole 2lb roll of .025 wire then got started on my welding table kit from tab and slot.
First off this is an excellent kit, laser cut steel goes together very easily and easy for a beginner or pro. Can be ordered with or without leg and caster kit.
I ordered mine without and then when i priced out the steel and 4 casters went ahead and got the leg kit.
So here is the construction switched to .035" wire for table weld up...3/16 thick.
In the above pic you see the slots and the tab design which pokes itself through slots on the top.
Essentially a torsion box design
Here it is all clamped up after the dry fit.
Then all welded
Then the slots in top welded
Add the legs sand and done
Nice flat top now for some fixture bits from strong hold.
I plan on making a plywood clip on overhanging top for this table to cover it and have it play double duty as assembly or work table in shop.
Also plan to get another thin sheet of steel to put on top of a set of draws i will make to go under top for storage of welding bits and pieces.
The casters are screwed into the legs, prior to installing legs a small square piece of steel supplied laser cut to fit bottom of tube is used to weld a 1/2" nut to it then it is welded into leg end. Caster then screws in for final assembly and these guys even supply a custom cut wrench to fit the caster nut.
Very happy with flatness and whole project, highly recommend this table.
