Welding Clamps

Nice work on the clamps. I'm thinking that if you attached "T" handles at the center points of your swivels it might be a little faster during setup operations. Mike
 
First class job there, Kevin. Wish I had a setup like that.
 
Thanks Tony! That's a good idea Mike, I might do that later.

So cool...I may steal that idea

Now you just need a very big Fresnel lens and it can be a giant soldering helper. :)
 
I did a set of these also but used 1" ball bearings and steel for the plates. Yours is much nicer looking than my version, especially the side plates, very nice. The steel plates don't grip the ball as well as I'd like, maybe time for new aluminum ones.
 
How did you machine the spheres? They look too smooth to be 3d contoured, did you use a corner rounding endmill?
 
I am considering building something like this using Aluminum or SS balls from McMaster. Which material would be better? What about brass? (I could cast those) What size should I go for? There is a HUGE price jump from 3/4 to 1". Would 3/4 give sufficient holding power? (I am doubtful)
Kevin- how rigid are these when locked up?
