For a low-budget expanding mandrel, an automotive "tailpipe
expander" can be held in a chuck. They're not as accurate as
a "real" expanding mandrel, but, can be fiddled into position for
trueing the ends of tubing.

Hi,
I have come across a problem. What is the best way to put a 2"x 8"
Brass tube in the mini-lathe. I find that using neither the 4-Jaw
nor
the 3-Jaw allows it to grip sufficiently. It seems to be a sort
of 'Blind Spot'.
I want to machine both ends but to make a mandrel that size seems a
bit OTT.
Any ideas?
Regards
Ken
