I need to crimp and bend some aluminum tubing in various places. I
might want to crimp the aluminum tubing and then bend it at the
crimped point.

I'm going to use those points for drilling and connecting to either
small diameter metal rod or connecting two aluminum tubes together.

I'm planning to buy a reasonable size vice and maybe attach half of a
steel pipe to each jaw.

Thank you.




Don't use a vice. It's not designed for that. One of my students tried
crimping the end of a 3/4" aluminum tub. Royally screwed up the a vice. The
vice jaws are a "lever arm" that extends several inches out from the center
of force, the screw. Mechanical advantage is the wrong way around. Better
to buy a cheap hydraulic press at HF or Northern Tool.
