RC Brushless spindle

[njhussey]

Hi,
New motor came, but again bad news. Motor came damaged due poor packaging.

Can this be repaired? How to balance it?

Good news is that C8 ER11A 100L Collet Straight Shank Chuck Holder finally arrived,
and it`s good quality. I also ordered dial test indicator to help me in my future spindle build,
and other project... very handy tool.
Cheers!

P.S. This topic is watched (by the counter info) but it`s been a while since no one write here.
Please help me with all my doubts and questions above.
P.P.S. Those bearings from above... can they handle spindle rpm?

Without doing a google on a bearing site I cant tell you if they're suitable. However whatever bearings you use will need a preload on them to stop them from skidding. The best bearings to use (apart from a double row AC bearing) are magneto (single AC bearings) bearings and preload them with something like bellville washers.

Can you return the motor as it looks shot (no pun intended)? I have no idea if the bearings are suitable, I have used that type but at low speeds. Good luck with the build.

I`ve got a 2/3 refund without returning it, so it`s my 2nd defective junk motor in collection.
So i`ll try one more time...( i think that you have the same joke about "3rd luck" )
I checked few companies for this type of bearings. All of them are low speed indeed, so no go.
Finally, thanks for your wishes.
Cheers!
