How to determine a skip-link chain length?

[Anonymous]

My 1950 BFG has no chain and I'm extreemly bad at math...

19" C/L front sprocket to rear.

26 tooth 7 3/4" dia. front sprocket

10 tooth 2 1/2" dia. rear sprocket.

EVERYBODY HELP ME before I spend too much $$$ on a chain that may be too short.

Thanks.

why dont you just buy one that is new. they are avalible i can get them but you will spend around 100 bucks. otherwise maybe use a peice of string but i am very weary of using old used chains on bikes that will be ridden a lot. remember that if that chain breaks and you have only a coaster your done and now have no brakes.
