Huge Rusty Leg Vise - Perfect Restoration
- Published on Jun 15, 2019
- In this video i'm restoring a very old Blacksmith Leg Vise.
My friend has found this blacksmith leg vise at the junkyard. It is huge and and very heavy, over 43kg. I really liked the size of it, the very long handle and the design from the spindle and the spring, that's why I decided to restore it and make a video about it. I think this vise is around 100 years old.
What I first expected to be a simple straight foraward project turned out to be a very tricky one. After cleaning up the two big pieces with the jaws I noticed that they don't close parallel. When the jaws touched eachother on the right side, they had a 2.5mm gap on the left side. To get this restoration done properly I decided to machine them. I made an aluminium plate to clamp the vise on the milling machine. To mill the structure of the rough jaws I bought two carbide milling plates and let them customize by grinding certain angles to them. The milling worked very well and I'm very happy how the jaws turned out. After the milling I did harden and temper them again.
As the holes and countersinks from the heart shaped part were very small and rough, I drilled bigger holes and made the countersinks bigger and clean for 10mm screws. I did recut the threads with a threading file, because I didn't had this threading die size.
I just cleaned up the spindle with files and emery cloth, removed scrateches and sharp edges.
The nut had a groove in it at the end, I closed it with TIG welding and turned the welding spots clean on the lathe. I sanded the rest with emery cloth and cleaned it up with a file.
I decided to mill the rectangluar washer clean, because it was very wavy and had an overall rough shape.
While I was recutting the threads from the two square nuts, I realized that they were slanted. For that reason I decided to make new ones.
I bent the spring symmetrical and grinded the very rough shape clean on the belt grinder.
After cleaning up all the parts I did sandblast them, made them black with bluing liquid and painted them with a dark green hammertone paint. After the reassembly I realized that the vise looks very dark overall with the dark green and all the black parts, so I would definitely choose a brighter colour for next time to achieve a nicer contrast. Besides that I'm very happy how this project turned out. My friend who allowed me to use his milling machine to remake the jaws was very fascinated by this leg vise and he really liked it, I'm going to give it to him after the restoration.
I hope you like my work and the video.
