Re: How to attach Bevel Gears to shaft when they are not keyed or have set screws
Funny thing, 1727 also ordered 3/8 inch bore bevel gears. I could have sworn that we ordered them finished, but they came as plain bore. In fact we may have ordered the same gears, did you get them form McMaster?
Anyway... we simply drilled and tapped them to fit 1/4 20 bolts. We will probably order set screws for them. We would be done, but a freshmen went and broke our last tap.
As for attaching the set screws, you may want to dremel a flat part on your shaft, or get the shaft with a flat side to it specifically for set screws. Or you could machine keyways, I guess it depends on your resources.
