Thanks for all the suggestions everyone. This is what I got so far:

It’s 1-1/2” frame stock and since it was a bed frame, it’s a pretty strong high carbon steel… but it welded up really nice and wasn’t too hard to cut/drill. The base area is just a bit less than 21” square (to fit under a Unisaw which is roughly 20-3/4” X 20-3/4”). A piece of 3/4” plywood inside gives a nice solid area for the machine to sit on, as well as raise it up enough for the dust collection port on the bottom base to clear the side rails. Once the base frame was welded up, I added two fixed wheel mounts on one side to accept some 2” diameter wheels secured with 3/8” bolts:

I made the wheels out of HDPE, which I recycled from milk jugs, and then turned them on the lathe to the proper size. I didn’t want the base to sit too high, and this setup keeps it just about 3/4” off the floor.

The last thing I need to work out is how to do the caster(s) on the opposite side (and then paint of course!). Since I have fixed wheels on one side, the other side really needs to be swivels, and I also need to lock the base in place when not being moved. I’ve considered something like those foot operated lifting casters, but haven’t made any final decisions as of yet.


PS: @lndfilwiz – I like the shopping cart idea for a welder cart… but I’ve got a MM210 which has it’s own wheels so that wouldn’t really work for it :)
