Mill vise jaw clamp/stop.......

[brino]

A few years back I picked up this 6" milling vise.







(.........and NO the battle scars were not caused by me, I got it used!)

I have wanted to build a jaw clamp and stop system that would allow removing the work-piece and putting it back in the same place.
Each jaw is just over 1/8" above the vise body.

I looked at a few different designs and builds and then came up with this.



It is made from 1" x 2" hot rolled steel.
I used 3/16" dowel pins for the sliders, a 1/4"-20 Socket-Head Cap Screw (SHCS) for the clamp bolt, a 3/16" shaft for the adjustable stop and a #10-32 set-screw for the brake. The brake also uses a small rod with a notch as the "brake shoe". It was something a I wanted to try and it works very well! With the set-screw just finger tight the stop rod is solid.


I'll be back in a few minutes with more photos...........stay tuned!

Here's just a bunch of photos showing how it's made.

Here are the main parts:





The dowel pins were a tight fit into the fixed jaw, but got thread locker as well.

More to come.......

Here's the movable stop and brake/lock mechanism..........








and here it is installed on the vise:








The stop rod is far enough below the jaws to be out of the way of milling.
Since the front part with the stop rod is only ~0.300" thick the vise can still hold fairly thin work.

Great job Brino. I really like seeing projects where the builder has made their own designs and decisions on how to accomplish the goal.

That’s an interesting scale there too, I don’t think I’ve ever seen one like it with different divisions like that. Pretty sure it would drive me nuts trying to remember what scale I was on but it sure looks intriguing!

I need to make one like that, it seems quite versatile. It would be easy to add an offset rod. I'll have you know that my mill vise has a mark near identical to yours but I am able to take full credit for the accomplishment
