Ordered my 3520A from Toolnut and am getting ready for its arrival.

Question 2: I still have a Jet Mini so need fixtures with both 1" and
1 1/4" sizes. Should I just get an adaptor to make the PM 1", or
would it be better to get new 1 1/4" inserts for my 2 chucks, and put
an adaptor on the Mini to make it 1 1/4"? I'm leaning toward the
latter even if it's a bit more money.
==================================
The larger option is the way to go. You're paying a substantial amount to
get a lathe that will handle a large piece of wood. Why would you want to
reduce the capability by a large percent? Remember that the strength of the
steel is roughly prpportional to the square of the diameter. 4/4 vs 5/4
inch, or 16 vs 25. There are other factors to consider in determining
strength, but why do it that way? The adapter won't be much additional
weight on the nose of the Mini, plus it will already be well balanced, so it
would be like adding a Super Nova chuck where you originally had an older
Nova chuck. YMMV
