John,What size is the 63 teeth gear on the OD and bore details.I have a box of old change wheels here from auctions and college clearouts, might just have one.
John,Is your dividing head the BS0 type with a 40:1 worm and wheel?If you have a division plate with 29 and 33 holes you could use compound indexing.You need an extra detent plunger to engage with the 33 hole hole circle. (I made mine with a piece of stiffish spring steel and rivetted a pin in the end. The division plate is not bolted - it is free to rotate and the extra detent (in the back of the plate) stops it rotating.To get 63 divisions you index 4 turns and 19 holes on the 29 hole circle and then 14 holes on the 33 hole circle by moving the plate. This doesn't give an exact division - the maximum error is 0.027 degrees.The downside is that the chances of getting something wrong are high unless you're very, very careful.A better solution would be for me to drill you 63 holes in a plate on my CNC mill. If you want one tell me what OD and ID. It would have to be in 3mm MS because, other than 16mm boiler plate, that's all I have. 63 holes would be very tight on a BS0 plate so the holes would have to be a bit smaller - meaning a smaller pin.Cheers.Phil.
