Where can I purchase these? I am making a few jacks and can't find these?

McMastercarr and search "Vibration-Damping Swivel Leveling Mounts". May be other alternatives on their site as well under fixturing/workholding.

Make one from a ball joint?

not directly answering your question, but they're not hard to make.....ball and socket: a ball bearing silver soldered to the end of the threaded section sits in bored recess forming the socket. A tiny bit of peening locks the socket - because its hard to hold i've done it with vise grips Just squeeze the edge of the cup

Or use a cylinder that the ball end goes in and turn a grove for an O-ring to keep the foot on the ball.

You could use a ball-end mill to make the socket, insert a steel ball with a threaded hole or shaft, and cut an internal groove to hold it in place with a spring clip.

I left the bottom of the bore a cone, I don't think it matters that its not round unless a key function is smooth movement. The KISS method.

At least one maker of c-clamps makes replacement swivel pads for their clamps. I just can't remember which ones.

So, I did a search.

They're really not hard to make. The majority of my C-clamps are flea market finds. The ones without the swivels are usually heavily discounted, so I have made over a dozen.

Thanks folks. I'll try and make my own. If that's fails I'll make a purchase.

why not use these (they cost almost nothing, hardened):

The last time I made a set of swivel head jacks I used the pistons from hydraulic piston pumps. Gave them away in 2005 though

If time is important I'd just make them. It takes longer to order up something and usually costs way too much for shipping on a small order to justify buying them unless you need a lot.

We're not talking about rocket surgery here either. A simple drill hole leaves a cone shaped seat in the swiveling button and a piece or two of HSS tool bits ground to a "sort of" half ball shape with support pin or quarter round cutters depending on what you have makes short work out of making a close enough ball end on the screw. After all you only need about 15 or 20 if swivel and it is a static seating. So no big deal.

I do like the idea of an inside groove to take either an O ring or a split wire spring ring. Avoids a lot of hammering and risk of going too far and pinching the ball in the socket.
