What do you think of this clamp for pipe notching. For those that dont understand. Pipe notching is required for welding two together, like roll bars or buggy frames. You chuck the proper size roughing end mill and feed the pipe. This clamp could be made to mount to the compound <img src="http://www.studiodepot.com/store/images/items/G9651-D.gif">
 
I think it would work for small diameter, thin wall stuff, but I would be leary of hogging out 2" schedule 40 stainless with it, as I had to do lately.
Those lighting clamps are cast aluminum, and not designed to do much more than keep a light from swiveling, with nothing pushing on it but gravity.
I bought an "Old Joint Jigger", and then bolt that to my milling machine table- it is adjustable for angle, and holds pipe up to 2" quite firmly. Made from steel, instead of aluminum, uses standard hardware, and easy to weld stiffeners on, I just use an R8 collet the right size for its shaft. Then you use a carbide hole saw, which are much cheaper than end mills when you get into larger pipe sizes. I havent priced any 2" end mills lately, but my guess is they get more than the 12 bucks or so a lennox hole saw costs.

I suppose if you were doing things like 3/4" aluminum tubing with a .060 wall, the little lighting clamp would work. And the Joint jigger is a lot more expensive than 30 bucks.
 
Thank you for the feedback. I had the clamp and the endmill was like $30. I just did some 1 1/4 .095 wall 1020 steel with no problems at all. I dont like the way those hole saw tubing notchers act.
 
Hey- if it works, do it. I have broken some lighting industry cast aluminum stuff before, so I am a little leary of it, but you cant argue with success.
When I clamp the Joint Jigger down on the big mill, it works pretty well, as it is very rigid. And I like the way I can dial in the speed with the variable speed head.
