View Full Version : anyone own an old Athol Machine Co. vise?

i just picked up an Athol Machine Company vise. from what i understand Starrett bought the Athol company and sold the Athol vises under the Starrett/Athol name. mine is from prior to that time. here is what mine has cast into it:


No. 40 PAT NOV 14 1871

it has 4" jaws and opens to about 8".

it has a quick opening/closing mechanism where the nut is a halfnut about 3" long and you can lift up about 1/4" on the movable jaw and slide it in or out. when you lower it back into the nut you can tighten or loosen the jaw as normal. the screw is a buttress thread and looks to be in pretty good condition, but the halfnut is shot. since i find it HIGHLY unlikely replacement parts are available, it looks like i have buttress threading project.

i tried cleaning and greasing the threads to see if they would work at all, but as soon as any pressure is applied the screw jumps out.

Yeah. I think I do. Maybe. But it's raining now and I don't feel like going out in the shop to look.

Mine is entirely different looking. It has like an I beam and the screw isn't enclosed.

I'll look when it is daylight and isn't raining. I do think it has Athol forged into it.

It stopped raining today, so I went out an looked.

Mine has "Athol Mass" on one side, and AMO or AMC on the other. No 01, I think.

On the one I have, the front jaw is stationary, and is one piece with an I beam. The I beam is fastened down. On top of the I beam, the rear jaw sits, and it is the movable jaw. The screw is above the I beam, and it open, and as a result is a little damaged.

i'd like to see a photo of that. from what i found the Athol Machine Co started in the late 1860s. it sounds like your vise might be even older than mine.

No, but I have a Rock Island No 294 that looks almost identical to it.

It might not be buttress thread, but it could be.
Very warn acme threads look like buttress threads.
Just a heads up.
Check out un-warn portions of the screw to be sure.

these are definitely a buttress thread. i'll grab a photo of the screw thread. the ends are almost unworn. i was looking at the screw on an old Parker vise i have, and that one is a square thread. it is kind of neat to see all of those thread styles and where they are used.
