I am working on a drive train proto, which requires a double strand sprocket on the gearbox. What i wanted to know if anyone knew where i can find one that is finished (bored, keyed). I also need the double strand sprocket for two 35 chains, not 35-2 chain. I have tried looking online everywhere, but i could only find sites for Linn and martin, but they don't sell them directly. I could only find double strand sprockets for 35-2 chain on mcmaster, and it was not keyed.
Any help would greatly be appreciated from team #8

Thanks!
