What does ".500 125P 1.0L" mean?

.500 basic diameter. .125 p = the pitch, the 1.0L = the length of one full rotation of the lead.
the Lead / pitch = #starts

Wow!
That's a small pitch.
I can't help you with anyone specific, but have you tried instrument makers?

That's the problem we stepped in quicksand.

I've had small 5 start worm shafts made in CNC lathes, no problem.
The finish can actually be better than having them produced on a thread milling machine.

However, the internal threads that you need may turn out to be the biggest problem.
Perhaps you could have them interpolated on a CNC mill.

good advice, we are doing that now I will keep you posted.

Thanks

That's much closer to being a helical spline than a thread.

Consider rotary broaching, both parts.

can some one give me a double check on the best wire M.O.W
pitch dia .4562-.4418.
using the van keurren & vogal equations.

using .054 balls, meas. over three wires = .5262-.5144
using .0675 balls, meas. over 3 wires = .5854-5720

Thanks in advance.
