Several years ago, I bought a welding table from Harbor Freight. I am finally getting back to using it, and have some questions. My table has three long slots on the top. I have seen others that have a series of (I think) 5/8" holes in them. I have seen a series of holding fixtures that fit the holes, but there seem to be little if anything made for the slots. Are these intended to be used with ordinary tools, such as "C"-clamps and those odd-shaped vice-grips, or is there a line of special tools I just haven't found yet? I think I bought the wrong table type, but it's a little late now.
StrongHand Tools does some clamps and fixtures for slotted tables. Also depends on the type of slotted table. There are the ones that everyone ripped off from StrongHand like the one Anthony posted or there are ones that are made up from steel bars that have spaces between them. If it's the one like the StrongHand one I use the spring loaded C Clamps with magnetic bases similar to the ones in Anthony's pic. Like these: https://www.stronghandtools.com/products/magspring?_pos=3&_sid=6b6cdd7e1&_ss=r
I have 2 of those tables from harbor freight, and like Anthony, I use c-clamps and c-clamp Vise-grips, and odd sections of whatever steel scrap fits the setup. Seems like I can never get to my original welding table… Here it’s relatively empty, and I have since removed the tube bender. This is the usual state of the bench. And yes you can have enough clamps, but I haven’t gotten there yet…
