WM180/DB7 mini lathe to cut 32TPI

[LainchyParticipant @lainchy]

I go to the LittleMachineShop website, "Learning Centre", "How to Articles", then "Change Gears for Threading" as my starting point. It is for a Mini-Lathe with only a 2 train gear set, not the 3 train that you need for your lathe. But in conjunction with your threading table, it gives a good idea what you need. I'm afraid it does not do it all for you, you still have to fiddle with the gear sets to get a good arrangement.

Some Imperial TPI could probably do with having additional gears to those that you have, something for another day perhaps.

I hope it all works out.

Cheers Neil. I'm still learning – 18 months in maybe, so this is helpful

If you could find, or make a compatible 21T gear, you could double up the 16 tpi set up,using it to to replace the 42T on C..

Or a 48T in place of the 60 on A in the 40 tpi set up.

Either might open up all sorts of new pitches for you
