Darren:
Bad news I'm afraid Stew,

Got the bit's OK but mine is a different thread,

You sent, as far as I can work out, a stylus with a 7/64 dia and a 48tpi thread,  (7/64, 0.1080", 2.74mm) 48tpi is the same or very close to 0.5mm pitch.

But 7/64 48tpi doesn't seem to make much sense with threading charts so it could be 3mm 0.5 pitch.

This is the same as my other dial gauge.


My new gauge has 2.53mm dia and 0.45 pitch (2.53, 0.100") seems to be no eqv tpi to 0.45mm pitch.

I guess in real life that translates to 2.5mm x 0.45mm

The wobbler, is that it's real name? seems an interesting device. I guess for measuring under something, such as what John was doing with my mini lathe when working out how bent it was  :wave:

Here's a pic as it's not fair for others reading without knowing what on earth we are talking about.... :worthless:

I'll have a look to see if I've got one the right size I've got a small collection.

The wobbler:- the way you've shown it is right, but if you look the round bit with the ball on the end can be unscrewed and screwed in the other face as well, very andy for clocking bores.

I'll post a pic tomorrow, of it in use.

Darren,

You can buy point sets such as this over here, but I can't find them at the moment. Mine cost less than a fiver for the set from Chester UK.
