Thanks bigpapa for posting the picture.
I have wondered why nobody ever made one of these since it always seemed like a good idea to me.
I'd been giving some thought for a while about how to do it and what to use to make it.
Then I happened to wind up with an 8" Stillson pipe wrench without a handle and an 8" Proto adjustable that I didn't need, and some xtra time.
I cut the tang, where the handle would normally go, off the pipe wrench and about an inch and a quarter off the end of the Proto. I Then cut the web out of the Proto with a Dremel cut off wheel and ground the interior to fit over the remains of the pipe wrench handle.
A trip to a friend with a welder got the two married together. I wasn't real happy with the way the welding turned out, so I pressed the Dremel back into service and smoothed everything up as good as I could. I still wasn't totally happy with the way it looked, so I mixed up some Marine-Tex and used it to fill in some rough spots and smooth things up.
Another bout with the Dremel and I was done. Interestingly I haven't had occasion to use it, although part of the reason may be that I put it in a drawer and kind of forgot about it.
