Following on from the previous observation that not all rods use the
same thread, I have have made a bit more progress in getting the various
makes of accessories to work together.

It seems there are two common threads in use. The cheaper sets seem to
use M4 0.7, and the more expensive ones (and most of the snazzy
accessories) appear to have 1/4" UNC thread.

(many thanks to Adam W for identifying the UNC thread for me!)

Anyway, a bit of messing about in the workshop tonight with my state of
the ark Zyto lathe has managed to produce a few adaptors like:

This lets the handy rod torch:

Fit on the M4 threaded rods thus:

(to any skilled metal workers out there, please accept my sorry attempts
at machining - although in my defence I would point out it is 23 years
since the last time I used a lathe!)

I made a couple of adaptors that also went from 1/4" UNC female to M4
male for use with the magnet and chain add ons.

I thought it 'turned' out OK :-)
