For about a year now I’ve been trying to refine the detail of my parallel jaw leg vise and I think I’ve got all the kinks worked out. My son put together this video of the bench I built this past winter that uses the chain leg vise. I’m in the process of getting quotes for the parts so I can offer these for sale. I’ve been making all the parts myself up to this point and I’m not a cnc. Take a look at the video and I welcome comment and discussions. It can be retrofitted in an existing leg vise or planed as part of the bench as I did utilizing the lower strecher. Thanks for looking, Jim

This is awesome Jim! You should also add that you can clamp work under the screw, something that cant be done with the St. Peters Cross.

Add me to your list, that is very clever. You need to patten that.

Thanks Ken. As to the patent, it is actually a long expired patent. About 100 years ago. I got the concept immediately but the materials depicted just were wrong. Which is probably why it never cought on and was lost in history.
I’ll keep you posted as the parts come available.

Great solution! Can’t wait to see this on more benches (including my own).

Mauricio, this might be the photo you were referring to.

My work is so varied I don’t think I would want the St Peters cross. Heck it took me YEARS to figure out the “best” bench/vise combination. A month age (and now 4 months after finishing the Ash bench) a buddy of mine gave me his 40 year old Ulmia workbench.because he was downsizing/retiring and it didn’t fit in his basement. I like the bench a lot and glad to have an end vise now, but it is not as versital as the one I built.

That is a very elegant solution. Do you by any chance have a copy of the original patent stuff? I a just curious to take a look at the guts of the design.

The can crush was great by the way.

As I was cleaning off the bench for the shoot my son wanted to put things in and squish then so I credit him with the idea the fact that the can was long was a bonus. Sent you a PM

Jim, PLEASE add me to your list to notify about any further developments and/or completion of the chain leg vise. That is just a brilliant idea!

I friend of mine, Derek Cohen has finally posted the installation of the chain on his leg vise along with a review . He did the two brackets where Scott just did the lower bracket. His review can be found at http://www.inthewoodshop.com/ToolReviews/AYSLegViseChainAdjuster.html be sure to look around his site he has a lot of great info.

I’ve uploaded the instructions for mortising the upper sprocket and wondered if people could take a look at it and tell me if it all makes sense. You can find it here. https://docs.google.com/open?id=0B69Qc1QBCySoQTMzN3N2VnN6aTA
Thanks for your time.
