ML10,

[Clive HartlandParticipant @clivehartland94829]

The Lead screw dial is a fixed dial, you cannot , 'Zero' it for a set position. The only way I can set it is to use the top slide until I can get 'Zero' where I want it.

My idea is to modify the dial and have a slipping scale which I can zero by rotating an outer slipping scale.

I have worked out a method of doing it but wonder if anyone else has done one?

Clive,

I have a Super 7 with a handwheel and I did have an ML10. I simply add the cut length from where the dial is positioned. The mental sums are good for exercise for your brain. Actually, thinking about it, I don't have any adjustable collars

Clive,

I did this to my Speed 10 many moons ago and it was well worth doing. It was so long ago I have forgotten exactly how I did it but from what I remember I used the original engraved dial, bored out the middle to form a ring and made a straight knurled outer part for adjusting the scale. If you want more information I can dismantle it and take some pictures.

Hi Doug,that would be interesting to see if it comes out to my idea. I think that I would trepann through the body and then make two insert rings to fit machined out step down spaces and then drill a few threaded holes to secure.

Maybe use Kilopoise to add drag to the set up, I must look to see if i have some wavy washers.

Right Clive, I pulled the dial off and took a few pictures. I used three spring loaded ball bearings as you can see, the balls run in a groove on the inside of the moveable dial. This technique gives a very smooth operation of the moveable part but may be overkill. Fitting the springs and the balls without losing some of the bits provides a great exercise in manual dexterity. If assembly is done inside a plastic bag flying ball bearings will be caught.

I am also a fan of kilopoise grease and put a small dab of it on the internal groove.

Douglas, thank you for the illuminating pics. all very clear. I will do a Photo session when I do mine.
