ive got a decent sized lathe, that could do most the work.
i might go with cast iron, difference between solid ally and cast iron is 3kg-4kg, cast iron one would weight about 6-7kg in total.
the difference in cost is hundreds.
but they might very well not be available in ally, due to strength

Hi

When I looked carefully the one I found was also cast iron

 

Know anyone with a milling machine and a dividing head?

It might be worth asking Bill Baker ?

If you check online you should see them listed but they’re not cheap! A quick Look suggested £250!

does anyone know if a 112 teeth top pulley 8m htd is available in aluminum?
ive not asked anyone like rick goosey yet.
i know i can get in cast iron one, but does anyone know where i can get one in ally, pre machined or with a pilot bore?
thanks jon
