Digi camera measuring lens threads?

[John S]

The pic below is a cam follower, looks quite
good when it's it filling a laptop screen. The screw thread though it is focusing on either
the peaks or tha backgrounds. I also have pretty shaky hands.

Looks like a Velo cam follower, you can clearly see the custom lapping marks where they lapped them in on the corridor floor outside the canteen.

Many happy ? hours spent at hall Green waiting for spares

That was flogged to me as being in good usable condition, I never
expected it to be good, but could see from his pics they had the original shape.
I did comment to him that they were not usable, would destroy my nice new cam,
I got a realy shitty reply asking what do you expect from old parts. I was originally going to Stellite
them but if I reground them I could have them cased. But I managed to find a set of Stellited ones.

I do have a tripod. I will try it.
