Who's of you make flat spot on motor shaft??
 

Just to know if all guys here make a flat spot with Dremel on motor shaft.

Is someoune here have ever had great result without a flatspot??

Maybe it's a stupid question, but i've order my Neu motor from RCM and i'am a litle scared about the fact of flat spot the shaft on a $300 motor:oh:

Thank you

Q is why you wouldn't want to make a flatspot? It doesn't have to be big, but if you don't have one its just relying on the setscrew being really tight into the motor shaft and never loosening a bit. With such a big motor, that's alot of power to trust to the little contact the set screw gets w/ the shaft.

Most motors have it already for good reason, but its not hard to do yourself, you really can't damage the motor unless you are doing somethign really really crazy

I've found that you really do need a flatspot. It doesn't need to be big. Just big enough for the set screw to rest on.

Ditto to the above responses...

Thank you guys. I'll make one one my new Neu motor:smile:

A flat spot on the motor shaft is absolutely essential. Anybody who is anybody will make a flat spot...

I guess that I am somebody, thanks ZPB. My self esteem has never been better!

Tsk, those arrogant Canadians! :wink:

The best way I have found to make a flatspot is to use a cutoff wheel with my dremel; I measure where I want the flatspot mark it with a marker put the motor in a bag and poke the shaft through so metal dust dont get into the motor. It is much easier to use the cutoff wheel than any of the dremel's grinding bits.

I used a tungsten carbide cutting/grinding bit. It slowly shaved the metal on my 1930's shaft - I thought it worked perfectly. Fast enough for me not to get impatient yet slow enough that I wouldn't be able to go too far too fast.

Psshhh, Those cheeky Americans! :na:

Whats "cheeky"? Please explain this insult?

I guess I'm a nobody, I don't use one and I have a Plett Big Maxximum, NEU 1515/1y,
NEU 1521/1y, and a Feago 8XL, all on cars running right now and never had a problem!

Cheesh, am I the only one with a sense of humor around here suddenly? :oh:

Lighten up guys! :party:

Seriously.... I don't know what "cheeky" means. Can you explain?
