Hi Bob,
I have a PSI maxi mandrel,and can tell you
it is set up for a "7mm" mandrel.You reference
to mandrel shaft A or B which SOUNDS like Berea
equipment.
Other places resell Berea such as Arizona Silhouette.
The Berea A mandrel is for "7mm",it's the one to replace
yours;its not an exact replacement, but will work.
And the B mandrel is for "8mm". I bought 1 replacement
shaft for my maxi mandrel from PSI at 7-8 bucks.
Then I found that Woodcraft has a kinda-similar setup that
they sell .
I tried the setup,did not care for it went back to
the maxi mandrel.But the replacement shaft goes in
the maxi mandrel and works.
Go to woodcrafts website and plug #141502 in search box.
Replacement shaft only 2.99.
I put " " around the 7mm (.2755) because its really just a
reference to the pen kit tube outside diameter.
The mandrels are actually .245-ish to fit the inside
diameter of the tubes.
Hope I didnt over-answer you![]

According to published figures, the Berea "A" mandrel is 0.247"+0-0.002. Several years ago PSI used to spec their mandrels at 0.243"; but I haven't seen figures in any of the current catalogs. CSUSA says theirs are 0.246".

The Berea "B" mandrel is 0.291".
