I’m building a workbench for our woodworking school here in Mexico and plan to install a Morgan 100A vise that we have laying around: http://www.ebay.com/itm/Vintage-Heavy-Duty-Morgan-100A-Woodworker-Vise-8-3-4-Capacity-7-Jaws-/130951237051

It had been taken apart and I’m trying to reassemble it, but I can’t figure out how to put it together. In the picture above, you can see a built-in stop that only allows a quarter turn of the handle. So I can’t push or turn the front jaw fully onto the rods. Help appreciated, Kim

Looking at the pictures of the vise, it looks like the handle can only turn a full 360° in the clockwise direction. When you loosen the jaws, the stop only permits 90° counterclockwise travel. It would appear that there should be a spring that permits the movable jaw to retract enough to clear the stop. Maybe rust is restricting full motion. Sorry, I can’t help you more.

Kim, I sure you already tried this but I mention a couple of things on the off chance that you have not tried them. First off if that was your vice in the link or it looks in similar shape you need to give it a good penetrating oil. The thread on that ebay link shows a bare shaft that appears to be top dead center when the handle rotates to the counterclockwise stop. Without having it in my hands I would assume that the full counterclockwise handle position is thread neutral and corresponds with the fixed head so it should just push in or on. Are you able to look inside the fixed head and see the location area of female thread? If I’m right, in operation you would push the vise snug with the handle full counter clockwise and rotate the handle clockwise to tighten.

casual – no, the vise shown in my link isn’t the shop’s vise. It’s in better condition. When I go to the shop tomorrow I’ll try your suggestion. Thanks. And thanks to you MrRon. I don’t know why a stop is incorporated in the vise in the first place.

The stop is probably there so you can reduce pressure clamping pressure for positioning.

Kim, MrRon, I found this link today, I think it says what I said, LOL only better.

”Quick Slide /Rapid Action. -This vise has a very desirable operating mode. When lined up, the moveable jaw can be easily slid in and out. When the jaw is pushed against the workpiece, a 7/8 turn of the handle allows 3/8” of clamping motion. The handle cannot rotate more than 7/8 of a turn. ”
