I drawn lots of tube down from big, ie 1/2 in down to 1/4, and 1/4in
down to 1/8in od. When you draw metal through a die it is swaged down to the
die size with a thou or so of elastic respring. If you drew some tube through
a die of the right size then pulled it back out, you then could cut out the
bit you wanted.

In the older drawing process the drawtongs do crush the tube end...


How do you get the large tube trough the smaller die in the first place so the
jaws can grab it?
