Right, Don, here are the pics. Hope they work OK, because it's 02.00am on 1/1/2013 here in the UK, and I cannot guarantee my sobriety.
A Happy New Year to all :beer:
Don suggests you might be viewing this 40 years on, in 2053. If so, did your Dad reminisce about the good old days, when things were done by cranking handles on machines to make things out of metal?

Many thanks for the pictures. So the ball bearing pushed up by the little washer spring generates enough pressure and friction to carry the collar around with the hand wheel?
andyf:
Hi Chris,
Not quite sure what you mean by "washer". In one photo, an arrow from the ball points to a hole, which contains a spring to push the ball against the interior of the dial collar hard enough to stop the dial moving.
Yesterday, I forgot to dismantle the thing inside a bag of some sort to stop the ball being propelled across the room when I pulled the collar off.
The ball is about 2.5mm diameter. It needn't be a ball, of course; you could use something like a shortened tiny panel pin with a head around 2.5mm in diameter, and its shank dropped down inside the spring.

I prefer the method used on my Herbert Mill. A knurled bolt down the centre of the leadscrew has a point machined on the end, and when you tighten the bolt gently it presses a brass pin outwards onto the dial to hold it in place. Quarter of a turn between having the dial loose and locked.

Neat mod Andy :)
I may have to pinch that for my Cadet. :dremel:
