Re: Bent my shaft!

I have straightened shafts many times, many are soft and gradual tweaking will help get it so good there's no vibration. Large stout pliers while supporting the unbent part or motor....Blips of throttle watching shaft stop you can see which way its "Leaning" when it stops...I have even done it motor installed. I have learned to have NO Space between prop adaptor and motor casing by means of trimming shaft with dremel (Shield motor from dust and filings) so bending does not happen so easily. If your shaft is already bent what have you got to lose? Good luck...(I have to wear reading glasses to see a tiny bend to tweak it out)

Thanks, Larry. I'm going to give the "bash it on the anvil" trick a try, but will be in touch if it doesn't work.

Good luck it should I would think.

Roll the shaft on the glass and gently straighten it on the hardwood block. When you get it to roll nice on the glass with no up and down movement try it in the motor again. In a pinch and taking your time you can get these small shafts pretty straight. Most of them are pretty soft so they bend quite easily.

KBC Tools sells O-1 drill rod which is not hardened in 4mm x 36" length here.

Or you can get hardened drill blanks in 4mm x jobber drill length - precision ground here.

Toronto for pickup or you can mail order.
$25 minimum last time I ordered from them.
Great company BTW.

Re: Bent my shaft!

It might depend on if it's a specialty motor made to fit that spot.
