Ideas for straightening out 71/84 tube mag?

[Aragorn243]

Not having any steel stock, rods, tools etc I found a marble that was the right size and shoved it through. I tend to fix things with whatever I have around the house and have been extremely lucky they actually work.

A ball bearing too if it fit.

How did that work out Brewer?

Sorry to be tardy on my reply, this is going to sound a little cave man but it worked. I had a brass rod about 1/4 thick two inches longer than the mag tube and threaded on the end. i took several washers and turned them down to just barely fit in the tube and attached them to the threaded brass rod with a nut. (it vaguely looked like a cannon ram rod.) then i whacked the end of the brass rod on the floor and forced the rod with the washers through the tube. i used a progressively larger and larger washers attached to the end of the brass rod and it pushed all the dents out. the tube works fine now. simple, crude but it worked
