Don't know if it will physically fit but if you replace the 24tooth gear with a 52 tooth one and select 11 tpi that will give you the same ratio, or very, very close to it.

Cheers Lard  :thumbup:

Chris ,,,,,,,, its well worth the effort to set up a small foundry  :dremel: :ddb: :ddb: :ddb:


Here it is machined up ,,, pattern needs to be altered as i had a slight miss calculation on the thickness  :doh:  ,,,This one will get me by until i cast another in cast iron this summer .




Now i can get back to  what i was doing  :ddb: :ddb:
