where can I get one of these CHEAP or can I substitute something that will work?

Question

I was replacing a small AC motor with a blade (Acme BB-700) and the compression ring went flying when trying to transfer the fan blade to the new motor and I have been unable to find it. Similar to this:

The shaft is 3/16" but the ring is obviously larger and compresses the plastic of the notched fan blade once over the shaft like this:

$6+ for one of these rings seems outlandish. Where can I find one at a far more reasonable price, or is there something else I can substitute to keep the blade on the shaft? Someone once suggested a small hose clamp, but another individual said that the side where the clamp is tightened, being unbalanced because it weighs more then the opposite side, over time would ruin the motor.

Thanks in advance.

How about a heavy duty tie wrap, or 2 with the ends on opposite sides. I believe suggested clamp was a "spring" clamp, not a screw clamp with a heavy side.

Darn, I wish I had seen this earlier. I think that suggestion might have been the best one of all. I keep all sorts of nylon wraps handy around here and I find them quite rugged for other applications.

Maybe "glue" the blade hub to the motor shaft using a drop or two of latex paint?Latex paint seems to stick to anything you don't want it to stick to.

It is not a "spring" so it cannotcompress the split plastic hub to retain it My default go-to in thatapplication is a spring hose clamp if one id available in a closeenough size (and it USUALLY is). Of course the secret is NOT to losethe original clamp in the first place!!!

Bob F · Answer

Tie wraps, especially heavier ones, can impose significant force if pulled tight. certainly better than nothing.In all this time, he could have just found the lost clamp.
