Not exactly the same, but I use this for mounting my solera. I used a flange and nipple, but it's essentially pipe mounted. Could easily be mounted to a pipe from the bench with a right angle and nipple. What it is is an air handling quick release for jack hammers. Mine is a middle size. There is one larger. Anyway, the arms lock the flange male piece into the female piece. I had to put some harder rubber in the bottom to make it more solid. It's not perfect, and not, necessarily exactly level all the time, but I love the way it works. Release the arms, spin it around, lock it back down.



Now, I mount it, using the same board, to a bench extension, which is held in that B&D Workmate vise. It gives me more space to put stuff down under the solera when I'm working.

I made one according to the book. What can I help you with?

I made one early on that clamps into a big leg vise on my bench....might give you some ideas. Fully adjustable (both height & rotation.). Invaluable ... I even use it as a go-bar platform.

The top clamping plate is split in half through the guidehole (the bottom one isn't). When you clamp in the vise, the split plate squeezes on the pipe & prevents it from turning. You can play with different materials with which to line the split guidehole (eg inner tube) to increase friction. Dropping unexpectedly is unwanted... I put a dowel pin (into my bench) under it & drop it on before clamping so it can't drop. You're exerting quite a bit of force when working a maple back... you may force it to shift from time to time if not clamped as tight as thought. Stuff happens ... A non-issue really: never ruined anything or caused me any anxiety!

Filippo, mine functions like Dave's, except I built it to rest in a front vise. Also, I have four layers of scrap wood gripping the pipe. When this big honkin' vise clamps it, that pipe doesn't move. The flange holding the cradle to the pipe has occasionally turned on the threads, but the pipe is secure.

I built one using 1" nominal pipe which slides very nicely into 1 1/4" nominal pipe. It uses a T bolt to lock it in position modelled after a welders pipe stand. Very solid. Some welding required. 1 1/4" slides into 1 1/2" pipe as well if you really want to be able to stop a truck.

Yeah, I think Patricks is an improvement if the goal is the "squeeze the pipe" approach.... contact as much of the pipe as possible for good grip (mine only contacts about 1 1/8" all 'round). Great to see the adaptations on the idea from builder to builder.

One other thing I'll mention about my scrap wood version: If you look at the photo again, you'll note that the pipe hole isn't centered. I can shift it a bit so a long pipe clears the ways of the vise, and that's the way I always set it up. It isn't lined. The "ring" you see around the hole is just an area that has been rubbed by the pipe flange. As I was posting the picture the other night, it occurred to me that this would have worked fine with just a 3-inch long pipe, because it's an ideal working height for me. I used a long pipe, because I thought I might need to stabilize it with another drilled wood block below, but that has never been necessary. I unscrew the pipe for more convenient storage, but I could have dispensed with all that if I'd used a short pipe. Also, a 3/4" x 3/4" lip glued to the front edge would allow it to rest on top of both vise jaws. That has never been necessary, but would be a modest improvement in the design and I'll probably add that before the next use.
