Welding Table

Made one at plant once don,t remember the size . It was about42 x60  inches x 3/4 in thick .  Thicker the better! Had 6 in vice with cabinet under neath.   Make closed cabinet with doors to keep out dirt and etc. Store rods and jigs in cabinet and before long you have enough weight so you don,t move when pulling on stuff in vice.

My preference for a welding table, is to use heavy steel strips or channel iron, with about a 1" gap every 6" or so... that way, I can bring clamps up from underneath to hold things in position while I tack it all together.

The other thing to keep in mind... is that oftentimes, people use welding tables for cutting, and sometimes, for working on componentry.  If cutting, realize that your torch will make a mess out of the tabletop, and send spatter around.  If using it for componentry, realize that said components will oftentimes leave oil on the table, and if oil and debris accumulates below the welding area, you'll have a nice little fire there.

Best to think really, really hard about what you want it to do, and then make compromises in your design according to the level of your priorities.

Also... putting wheels on it... make sure they're hard, noncombustable wheels, preferably large diameter, because you'll be rolling on spatter, and dropping hot stuff all over 'em.  Next... if you're expecting on beating on it, and making it heavy enough to take that beating, expecting it to be mobile isn't compatible with an incredibly massive table.

Finally... when you build your table, build matching 'work stands'... something you can easily slide around, to give you an additional support point at fairly-close adjustable height.  Invariably, a guy will be working on something like a sickle mower, and the bar will be flopping on the floor, causing the rest of your work to jump up.  Rolling a stand underneath the far end (it's several feet off your table) really helps.  For fine adjustment, I make my work tables out of old trailer jacks... just turn the crank a half turn to change the height.

I just bought a table with a 6" vise on an auction last weekend. It has WD frame rails welded together and a sheet of 1/8" steel on top of that. At least I saved some allis iron from going to china. I am also thinking about adding 2 sets of casters to it so I can move it around.

My dad built one out of 2 steel wheels off of an old pull type combine or somthing. one wheel sits on the floor with 4 pipes sticking up and the other wheel is the top with 3/4 inch plate welded on top. Make the top a couple inches bigger than the wheel for a good place to clamp and hook ground.
