I do not know what sizes I will be making yet, but with my luck they will be all different. I was just trying to get something that would fit a least a few different sizes. Arbors are easy to make, but would not like to have a lot around that maybe just gets used once. Most I think will be 6" or less, but I do have to make 2 that have the teeth facing inward and about 7" dia. inside and this would not work with a arbor and will have to be milled. My 4 jaw chuck is about 2 1/2" dia. and I could make it close to the chuck if it is bigger than that and maybe not use a tail stock if the material is soft like alum. or brass. I am just trying to think of a better way to do them. When I get one to make it will be a rush to get them done for a store near me because to send away for them takes too long for them and the machine will be down and that is money.

I bought a neat arbor for a slitting saw from BUSY BEE here in Canada, I believe it is import but will fit a number of saw hole diameters as the sleeves are telescopic and spring loaded. It would work for small gears from about 1/2 hole dia to at least 1 inch. You coulod hold the arbor in the chuck it seems to be quite well made. tom
