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 .

Rob, you are just the ducks gutz.... hell you get a good finish.

While you make it look so simple I wonder do the majority of the guys here understand the labour it takes to do what youve just done? Thats completely aside from the skill level required.

I suspect not.....

Looks great mate...  ee ahhh noo eya, isnt that what you Gordys say?
