blank 3/32 chain wheels??
Does anyone know where I could buy a blank aluminium 3/32 chain wheel?? I have googled, but found only motorcycle ones.
Like the picture attached of a motorcycle rear one, but for a bicycle and for the front.....

You might try contacting Specialites TA to see if they'll sell you a chainring blank. That's how most are made, the aluminum sheet is cut into a disc, teeth are cut into the disc, and then the cutouts and other sculpting are machined in before any finish is applied.

Found a solution..... 415, 420 and 428 motorcycle chain are all 1/2 inch pitch. So I can just buy a 50 tooth aluminium rear sprocket for a motorcycle and pop it in the lathe and spin it down to take a 3/32 chain.

you can't find a 50T chainring to fit your BCD crank?
