Hi All,

does anyone know where I can get a 15 tooth, 5/8" bore sprocket for #25 chain? surpluscenter does not have it.

theres no such thing because of the wall thickness, when i did a smaller tooth count , i had to have the bore pounched out on a lathe

I have a lathe , whether or not ill be able to bore out that gear on a smaller machine, i have no clue..go ahead and send it , there wont be enough wall for a keyway but i suspect that wont matter

heres the right srocket to bore ( READ ENTIRE REPLY )

that leaves me having to bore 1/8th or .0625 off the inner wall.( machinist math , reduction of 1/6th on wall = 1/8th bore increase)
My biggest concern is the hardness of the steel..The teeth arent hardened but thats no promise on the shaft.for a better chance of a final reeming pass since i dont have a .625 reemer would be to send along a a 5/8th bit with the sprocket. hell i may even try to punch it with the bit.

this is the cheapest one i can find , maybe u have one.. YES, i can do the job with a boring bar but if i need serious torque to make the bore the boring bar aint gonna handle it.
And a reamer is even more. Dont buy the bit , at that rate u may as well get it locally machined ( 25 bux ish)
I guess send it here cheap , ill send it back cheap and we can call it a day.. If i cannot get a cut going on the hardened steel i wont even start and ill just mail it back

Thanks Rob. I may be able to get the engineering department at my hotel to do this. If they can't, I'll send it to you. I bought 2 of those sprockets by sheer guess work a couple days ago. They should be arriving today.
