I continued with the teardown, cleanup of the Wilton C1 today.
drivesitfar and 454ragtop were correct in that the pipe jaws were retained by spring clips on the back of them.
I got those out, and decided to stop fooling around with the jaw screws.
It is times like this that having a mill makes things soooo much easier.
I mounted the vise body on the mill table, selected an end mill that was just the diameter of the head on the cap screws retaining the jaws, and bored the heads off the screws.
This makes it possible to pop off the jaws, grab the screw shanks with vise grips, and get them out easily:
With all the jaws off, I blasted the parts, cleaned up the torch and grinder gouges in the vise, and milled off the anvil surface to clean it up:
The end cap was pretty beat up, dented and had a nasty crease in it, but at least it was still there.
I took a hammer and some shaping tools to it, and got it as close to original dome shape as I could:
Then I sanded it and buffed it, and it came out surprisingly well:
With warm weather forecast for this weekend, I should be able to get the body painted and ready for re-assembly.
