Simple Vice Stop

Both spellings are OK (or either) – in England anyway.

What I meant was, if you want to set multiple parts vertical in the same relative X position.

When I worked as the metals-storekeeper for a company making screen printing machines, most of the millers made similar stops by cutting a slot in a piece of b.m.s. angle held to the vice by a screw tapped into the casting behind the fixed jaw.

They were working on batches that could be anything from a few to maybe 50-off, perhaps even up to 100, components.

Should still work as I said with the stop fixed to the end of the vice jaw. Probably need to push small items up against the stop with something like a steel rule as the vice is tightened.

Also best to set the stop truely vertical with a square or ground block.

This is what I use for a stop, M6x1 setscrew in a hinge up guide bar, in this case it allows the part to extend out of the jaws so the corners can be radiused, i end done ready to turn around for the other end.

Usually I set the left end of the rear vice jaw as X=0 and the face of the rear jaw as Y=0, top most surface of the work is Z=0

Mainly only making small aluminium parts (see my Album) so vice jaws are only lightly closed, but enough to hold the workpiece.
In the picture below the stop has been swung back clear after setting the part in the jaws, the end of the work is set to the OD of the tool rubbing before moving to radius both corners.

I made myself one this afternoon, its a bit shorter at 25mm simply because I had some 1 inch x 3/8 inch bright bar so took a couple of slices off that. I dont have a 3mm reamer so I turned up a couple of pins for a good fit into the drilled holes.

I have some repeat parts to mill in the morning so it should be put to good use.

Thanks Jason.

p.s. forgot to say I fixed the pins to the block with 638, which worked fine.

The threaded hole in the end of the vice jaw is to hold a piece of flat/square barwuth a hole towards one end the size of the threaded bolt, you then fold the bar down and lock it tightening the bolt and there you have it, just slacken and fold out of the way for normal vice use.

In this photo, you can just see the hole drilled through the rear of one of the Bison vises for a stop made from 8mm studding. Both of the Bisons have been drilled, and I found out they are made of SG cast iron.
