i was looking for suppliers of 360 or even 180 tooth worm wheels, didnt find too many that were reasonably priced, sacrificing quality of course.
but came across this suplier, fairly expensive.

did you machine the brass wheels in your drive? i'm guessing you machined the aluminium wheel. where can we get such wheels?
I don't have access to a lathe so cant machine as such.
the overall gear reduction in your drive seems fairly large with the worm stage and the roller wheel stage. what is the actual reduction you've achieved?
for single start worm wheels, would you know if the sliding friction is higher or lower with high and low pressure angles and lead angles?
