Hi all. Any one know about doing set screws.

I have a 1/2 shaft that has a keyseat: 1/8" X 1/16" in it and I have a hub with no keyway in it that is going onto the shaft.
The hub has a set screw in it that will go into the keyseat but I was wanting to know about installing another set screw in the hub 90 degrees from the one that's already in it.

Would I have to make the other setscrew the same size or can it be a little bigger or do both have to be the same size?

I have no way to make a keyway in the hub. Also this part is running at slow speeds and not under much load.

Thanks
 
Whats the question? lol Just drill, tap and install set screws wherever and whatever size you like that you can fit.
