[Shop-talk] Epoxy recommendations?

[Jim Juhas]

I have never had long term success depending on epoxies of any kind 
holding in high torque, or even low torque, situations.

If there's room for this, I suggest a bushing that would encircle the 
impellers shaft where it goes over the motor shaft.  The metal bushing 
would be drilled and tapped for a couple of set screws that would reach 
down to the metal shaft.  Does that sound feasible?

I think it would be tough to drill and pin through the 1/8" shaft on the 
motor.
