Sprocket and chain confusion

[HeadSmess]

the ones with the points facing outwards

precisely 1/2 ID, and the OD was something like 7/8 from memory. too cold to sift through a box that maynt even have one at the bottom anyway... but you end up with a splined shaft that can be re-used several times as it wears, easily replaced if designed right, and as you saw by the price...costs virtually nil...

And thanks for the other info as well. Your sense of humor and borderline sarcasm at times make the monotony of all the technical info a little easier. Anyways I'm glad you found my little thread and glad you helped out with all the info. Thanks again

why thankyou
