To help someone out this side of the pond can anyone tell me the DP of the change wheels on the little 6" Atlas lathe, it's a MK2 if that matters.

Also anyong got a metric thredaing chart for one as the guy is looking for a 21 tooth gear but that doesn't sound right.

I know Myfords use two 21's in their train but I thought they were unique in this and other machines used something like a 38 / 45 ratio [ or such] .

I remember a post from Evan ages ago for his SB to cut metric and he related to something like this ratio.
