Thanks, everybody, for all the suggestions.

My best idea, right now, is to waste an old vice grip welding clamp and
replace the jaws with pipe clamp. Then I'll make this northern tool lever
suggestion out of a couple scraps of tubing.

I won't build till Tuesday, so I got a couple days to sleep on it.

I came up with some ideas based on the clamps used on the tubing used
in the oil fields. But way too complicated to build for pulling just
50 tubes.

So instead suggest you use something which has no metalworking
content.

Consider making a loop of rope or webbing. Tie a prussic knot around
the tubing. Pull with a Farm jack or a long ram hydraulic jack. Tying
a Prussic knot will take less time than bolting some blocks
together. I pulled about 4 feet of 1/2 inch rebar out of the ground
using this method.

Use Google to see what a Prussic knot is.
