I've had bad luck with tapered arbors, the gear blanks are too narrow and tend to cock off to one side. The pressure/hammering of the cutter on the workpiece doesn't help. Better, I think, is to make a stepped arbor, and even your beat up lathe can make them. They force the blank to be square, up against a shoulder like that.


Threads are optional, a press fit if you want. I prefer using a nut though.

yes I was out far enough that I could see it without moving the cutter to the center of the shaft, but its what I get for using the same center height as I used on the part I was working on in the pictures I posted earlier. lesson learned don't trust previous setups.

And yes I can make arbors like that, just have to get it in gear and make a couple I have a couple feet of 1 inch 1018 should work ok can put a couple different shoulders on one shaft.

Thanks for the picture I was visioning the shoulder being in the middle of the shaft. got to make up a couple dogs I don't have any, guess I could just drill a hole in the shaft and bend one end of it the grind a couple of flats on it.

thanks
