Hi JimE & Roy et al,
I tried the method of reverse clamping on the chuck suggested by JimE
but it didn't work for me.
However, would you believe it Roy, I have three different sizes of
exhaust expanders in my garage workshop - including one of 1 and 5/8"
to 2 and 1/4" from my Race Car building days. I guess I am not
thinking laterally enough for the mini-lathe yet - which must mark me
out still as a "Decky" (:o)
HAPPY NEW YEAR from dark and wet Northumberland
Regards
Ken

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?

Ken
