Does anyone actually know the thread dimensions and

Having a quick google, I come across the description
32mm

That is the actual outside nut size. I am referring to
the threaded bit
inside.

A/F [1] and someone's upgrade story finding that a
bicycle spanner fits to
tighten it. Knowing the story of Rega's beginnings could
it be possible
that you might find matching components in a cycle shop?

also found claims that tightening the base nut too much
could be
detrimental to the sound...

Overtightening anything can be detrimental :-(


Probably worth giving Origin (the arm rebuilders) a
call - they may tell
you if Rega don't.

That's an idea.

I've got a P3-24 which one day I'd like to mess about
for changing carts from Rega's (fine) own. I'm just a
bit tight paying for
a set of spacers at the moment, £15 each - for things
stamped out of sheet
metal ;-)

Why no VTA is beyond me :-(

Well, a few years back, I designed a VTA adjuster for my
Rega with the help of my friend, a skilled machinist. He
could not find a standard tap to match and had to cut the
parts using a custom-fashioned cutter tool and the thread
cutting facilities on his lathe. I will ask him if he
still
has the specs.

That would be greatly appreciated :-)
