Wilton 4” bullet (seized dynamic jaw)
So I saved this Wilton 400 from the dumpster at work the other day. They were going to pitch it because it was seized up. It spent its entire life outside in the Michigan weather.
So my problem was the dynamic jaw was seized up and the retaining horseshoe washer was missing with all the screws broken. I’d assume the the screws broke while someone tried to reef down on the handle trying to get it to open up even thought it was seized.
So I tried driving a wedge in between the jaws and soaking with kroil couldn’t get it to move much if any. I decided I was going to make a “puller” if you will. I drilled and tapped 1/2-13 holes in one piece of key stock. Then in the other I drilled two holes one step up from 1/2 about halfway thru. Just to stop the threaded rod from walking all over the place. Then I took some 1/2 all thread and welded nuts on the end.
It ended up working perfect. I didn’t have to wrench on it very hard at all. I think it just needed solid direct pressure.
Once I got the jaw out I was able to use the spindle without the jaw to push the dust cap out of the back. Luckily I read somewhere on the forum about doing this and it paid off tonight for sure.
Just wanted to share my experience with everyone in hopes that I can help someone out in the future
