Thread: Diy brushless spindle
Jonathan - Yeah you save yourself about £5 but have to wait 2 - 3 weeks, I bought mine on Thursday night and it was delivered to my works (no Sat deliveries) Monday am, you won't get that with Hobbyking One of these days I'll pluck up the courage and order something from there :tup:
Turnigy motors are good motors, I've had a few in my planks and only had a couple of issues (loose magnets and noisy bearings.)

Single AC bearings finally arrived today, this is the second lot as the first lot never made it...
Run out of time to do the spindle this side of Xmas as off visiting relatives after the end of this week till the New Year!
Sorry, I'm on lunch at work so I didn't have time to look through the thread... you are putting one bearing in front and one in back (of the housing which is out front of the motor), correct? What type of fit are looking for on 1) the shaft and 2) in the housing. Press fit I'm assuming, but roughly how much force?
I'm assuming this will cause some pre-load on the bearings... and with more interference on the fit, the more preload on the bearing.
Have a good holiday... anything I should not miss up in Newcastle? I'll be there for a couple weeks...
Hi Adam, not been on here for a while as work was mad (trying to get a quote out and clear my desk) last week, 57 hour week...
I've tried the bearings on the ER16 collet shaft and they are disappointingly a loose sliding fit...will be a light press fit (heat housing first and slide the back bearing in) in the housing with Bellville washers pretensioning the inner races. Will have to locktite one bearing to the shaft and I guess leave the other a loose fit to keep the pretension? If the bearing starts skidding on the shaft (like Mark's did) then I'll have to locktite that too I guess.
I don't know Newcastle or the surrounding area, never been to that part of the country yet, so can't help you on what not to miss I'm afraid!!
Hope everyone has a Merry Christmas & a Happy New Year!
Hey guys how is this thread progressing?If the nagging gets really bad......Get a bigger shed:naughty:
I'm working on one with two brushless motors, ATC and water/oil cooling. It will be a while until I post the build log, but my prototype for the ATC works. Having difficultly sourcing disc springs/Belleville washers though...

Jonathan, I found these people http://www.bellevillesprings.com/bel...e-washers.html and was quoted 100 off D18842 for £15 (min order charge else would have been £10.33) with P&P £5.50.
Progress as far as I'm concerned has ground to a halt at the moment as our lathe at work is poorly at the moment...
