Not really Ralph. The RELS handled all taper cuts and threading. I made
the bronze "screw" first. I screw-cut the internal thread and tried the
"screw", a bit tight so I re-cut the internal thread about .004" deeper,
perfect. It is actually an M42 x 1mm thread but I am quoting in " so you
do not need to translate <G>. The DTI I used for concentricity checks is
imperial that is why those checks were in thousands.
Bit by bit I am working on making the an imperial RELS for you guys with
imperial lathes.

Nice Richard, that inside thread must have been a challenge.

Today and yesterday in fact, made one of these ER32 collet blocks ( I
did not make the actual collet ).
Quite pleased as the concentricity between a ground bar in a
collet and
the faces ended up at .0005" max.
