It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

tolerances once you get the basic pitch and disasters. I would get a reputable lead screw manufacturer to made me one from the old one. Although I've never seen one I understand they do make
multiple start lead screws.
All our profile grinding equipment has the Acme Centralizing
Thread Form.
I have some Screw Pitch Qauges similar to the ones in this link that are a good starting point, putting you in the balpark, so you can refine your measurements.

I had to order a good quality 3/8-24 die set for an aircraft part. Everything seemed fine until I tried to use the "GO" guage. The die was incorrectly labeled. It was a double start thread and I had the devil of a time geeting it reordereed correctly because our buyer could not understand the distinction.

I've been a buyer; it's not fun.

As I've h I've posted before the Differential Screw Micrometer gave me a little trouble at first, but since we used so many I had to understand them.
In the US an interesting use of the multi start thread is the gallon milk container cap.
junid,
I misstated in my last post as we use both the CTF and TTF from. The unmodified machines have the TTF while the modified machines have the CTF. I don't know why and the designer is no longer with us, Cancer got him 3 months after he retired.
