Just to remind y'all that not all welds look like stacked dimes, here's my current project:
I recently ordered a 5" Palmgren Industrial vise, made in Argentina. It's a close-out and for $60 with free shipping, it was a no-brainer.
I've been wanting a vise on a mobile stand, both for use outside and for places in the shop where I need more room than my bench affords. I also wanted the vise mounted lower than those on the bench--nearly 4' from the floor to top of jaws--for things like grinding and hammering.
So, first thing is to determine the height I wanted. Best thing seemed to be to make a mock-up that was easily adjustable to try out different heights. Hmmm.....
Yeah, that does the trick. Looks like I want about 39 1/2 inches from floor to top of jaws. Low enough for comfortable grinding and hammering, but I don't need to bend over too much if I want to weld something in the vise.
Next, a trip to the boneyard for materials.
5" square X 1/4" wall. Maybe overkill? Weighs a ton. Maybe some 3" well casing is plenty stout? Got lots of that.
What about a base?
Part of the platen from an industrial scale that someone managed to kill. 22" square, 2" deep, all stainless; 3/8" 16 threaded on each corner for leveling feet. I think it'll do.
Now to make it portable.
Always salvage casters. Fixed SS body, ball-bearing, 2 1/2" urethane tires. No idea what the rating is, but they look plenty stout. Just what the doctor ordered.
I cut off the mounting flanges, used a piece of 3/8" plywood for a spacer between the floor and the wheels (after installing carriage-bolt leveling feet) and tacked them in place. Finished the welds on the bench.
The 3/16" plate is the one piece that isn't from the boneyard--it's left over from another job. The foot-square plate is welded to the web from beneath. Should be plenty stout and the 3" well casing looks quite adequate. The exposed web of the scale platen affords lots of good places for a ground clamp.
That's as far as I'm going until the vise arrives.
@deezil provided me with some measurements of the vise, but I prefer to have it in hand.
Now that I'm looking at this, I may just put a small table-top on the pedestal stand and mount the vise to a separate plate so I can clamp either the vise or my bench grinder to the stand.
I'm using standard E70S-6 X 0.030 wire for the welding. It's a long ways to the salt from here and the stand will live in the shop most of the time.
