I don't recall if I ever posted what happened with that post vise stand, I think I did but I'll repeat it here and give the current sitrep on it.
soon after Brad and I welded it up, I was using it, banging on something in the vise and it snapped right at the welds. What I've learned since is that brake drums like that are cast iron and don't take to welding to steel well.
Brad (eburgblue) did an awesome job teaching me to weld and the welds he made were the best I've had the pleasure to see but that confounded cast iron beat us.
So I've sloooooooowly been working on finding a new way to mount it and am close to being done (pictures pending!)
I flipped the drum upside down and put a steel plate under it. Drilled countersunk holes though the plate and have 4 3/8" bolts coming up through to the plate on the vise stand. I need to cut a wood filler piece to take up some of the threads on the bolts. Then once assembled I'll fill the upside down drum with sand to add weight and give me a place for tools.
If I finish tonight, I'll post the pictures!
