Big C-Clamp, replacement (big) pad

[bigmike989]

Hello. I acquired a beautiful Williams CC-412, 12 inch C-clamp, minus the pad. Do you know of a source for a replacement pad that will fit a 0.67 inch diameter ball? McMaster ones only go to 0.575 inch and the Westward 10D573 looks to max out at 0.50 inch. Thanks.

Consider this a bump, but I just used a drilled out nut, welded a washer on one side, then cut each side about halfway down, install over ball, peened in the top, and tack welded the curfs.

Not pretty, but it works.

I have a couple Bessey clamps fixed like that.

Wonder if Wilton parts would fit.

If you have access to a lathe, make your own out of 1.5" round stock. When I first got into industrial maintenance, the plant I worked at threw out perfectly good Wilton 400 series c-clamps with missing pivot feet. Working night shifts, I rescued those clamps and made new feet. That's how I started my collection.

Thanks all. No-go on a lathe. Hunting down sources for a Wilton. Will report.

Well the Wilton 2901310 was a no-go, too small of a hole for the ball. I also realized this clamp is some home brew item as the screw is too short for the pad to reach the bottom jaw.

A lot of the commercial big ones don't close to zero, which is what a short screw would do. Most cases, why use a 10" clamp if you want to go to zero, except when you need to reach over an obstruction.

Reading is hard.

There's a lot of folks on here who would turn you a new piece for the price of postage, myself included.

You mean they didn't put a padlock on the trash chute? I know of one corporation that goes to great lengths to make sure anything they throw out is not recovered by either their customers or their employees.

More than 40 years ago. I imagine in today’s workplace, they wouldn’t allow me to make my clamp parts on company machinery and time.
