What table top is that? Seems a bit too nice for welding a jig to. I might just make a small table for that. I have seen some jigs to drill in holes for table tops as well. Nice effective jig design
It's just a cheap small Welding Table from Northern Tool I believe. they sell them online as well on Amazon. you don't have to weld the Jig to the table. You can weld it up to a piece of large flat plate steel maybe 12 inches by 12 in which is exactly what I've done since this video that way I can stow it away behind my toolbox or something and then just toss it up on the Welding Table whenever I need to use it.
