I need a little help

I am trying to make a set up using a electric motor to do some shaft cleaning and personal tip repair. I need a part to connect the motor shaft to a male drive pin that will screw into the shaft.

Does anyone know where I can get something like this?

These are the drive pins below.

P.S. I'm not much of a draftsman so my apologies.
 
You could always just mount up a drill. Then you can chuck up whichever pin you need. Single pins can be purchased cheap. I've seen some pretty sporty set-ups using a cheap drill. Works fine for shaft cleanings and such. ;)

I wouldn't suggest it as the design is flawed.
The set-screw that is securing the shaft in the bore is also pushing the center-line
of the coupler away from the center of the mtr. (if the mtr. is the .650" hole).
Doesn't matter which is which.
Notice the set-screw in the other hole. It's pushing it's shaft even more off of the center-line.
Even if you were to put both set-screws on the same side, they would be pushing the coupler out of concentricity.
Bottom line, it's going to vibrate pretty bad.
Buy a lathe and be done with it.

Any local machine shop should be able to make it.

What he said.

I would also suggest that you carefully measure the motor shaft.
It is very likely to be .625.

Even better - take it to the machine shop with you.

FWIW - I prefer a CCW rotation motor - then the shaft will spin the same
way as it normally would in a lathe.

Hi,

Get a Lovejoy coupler and bore one side +.150. The LJ will make up fit up the shafts are not perfectly aligned.

Try Mc Master Carr.

Couplers? We don't need no stinkin'.....

Well, you can chuck up on the service mandrel with a 1/2" drill and away ya go. No need for couplers this way. (Oh yeah, what Kevin said)
Once upon a time (not lately) I did my tip work that way: drill on the floor pointed upward, the shaft coming up into my hands where I did my sanding, etc. I operated the drill with my toe. This is not necessarily a recommendation, I'm just saying....
You would really enjoy an inexpensive lathe though.
 
Thanks everyone for your help. I managed to find a torsion flex coupler that was processioned honed and should keep the service mandrel centered with the motor shaft. The motor is a servo motor that I got off of another machine that I rigged with a foot pedal rheostat.

This set up should work ok for what I will be using it for but it is not a lathe. Obviously I wish i had a lathe but I'm making the most of what i got.

Once again, thank you everyone for your help and advice.
