I wanted another Vise for the bench, and found this in a old "Shop Notes" Vol 20, Issue 120. It looked good and it will raise the work up to a more comfortable level while standing.
This was made with 8/4 Ash that I had on hand. After running it through the planer and jointed one edge I ripped a 4-1/2" strip out of that 6' board. All of the parts and pieces came out of that, a little resawing for a few parts. The vise is 18" high x 4-1/2" wide x 4-1/2 deep, then the arm in back extends 5" onto the bench. The Acme threads I had to order from McMaster Carr. I finished it with a few coats of Danish Oil, except for the auxiliary jaws. There are 2 sets of jaws for this, a smooth and one that has groves for round objects. The Jaw capacity is 5".
I fun build and which involved a few tricky cuts. I had to use Copper pipe for the Ferrules on the Hub assembly, could not source a short piece of steel pipe locally. But my version looks better.
I mounted it to the bench corner, drilling the hole so it could be turned 90* and attach to the side. I also drilled a mounting hole over on the other side of the bench. I have put this to use already, nice to have an extra set of hands in the shop.
And I even used the last project posted, as a drying rack today.
