My best table (well maybe I should say favorite) is a slopped up piece of junk I salvaged from a buddy's welding operation where he had rescued it a few years before from another junk pile. It has huge rubber-on-steel wheels, and looks like it was thrown together, and it was. It had a 1/2" plate that was chopped up and drilled, and painted. It wasn't quite square. The cross member was welded on crooked someway. I took the plate off as it wasn't large enough and got a sheet of 4 x 4 5/16" metal plate. I laid out 3/8x 2" frame with the same for cross members and tacked the top to it. I leveled the top up as best as I could and tacked it to the rolling chassis. It came out remarkably flat except on one corner where it is a little low. I know where the corner is, and can address that issue when it becomes a problem. I've made several thousands of dollars on top of that table. I'd post a picture of that one if I wasn't so embarrased by the looks of it...Well, maybe I will anyway to get the point across that you don't need 1" thick top to do good work and you don't have to spend much money to get something that works. I built another table and built it well, and I use it in some of the videos...It's too nice to use. It has wheels too, but I used smaller solid steel wheels on it. It rolls ok, but doesn't glide like my junky looking one. I bought another table for light TIG and fit up. It's small and well, when you buy it on the cheap like I did you don't pass it up.
I think I will go out and take some pics and just post the junky, embarrasing table just for kicks and give you guys something to laugh at...or to make you feel better about yourselves and your situation and give you hope.
