Diy Brushless Spindle

[njhussey]

Yes I looked for a while for 8mm angular contact bearings but only found one supplier, on eBay in america and not cheap. That was for single row, couldn't find any double row that size.

I wouldn't expect normal bearings to last long if you're drilling ... but nobody really cares as they're so cheap.

I'm only cutting balsa and ply to start with so they will do, but then for the little extra it would cost might be worth getting a larger motor and 10mm spindle?

Also you can get ER16 collet chucks with 8mm shank:

Looks good, will give more tooling options later on...

That's slightly worrying - depends how you go about it.

Going down the skate-o-rail option or might just do a quick and dirty joe2006 type to get it up and running...yes I know, i know, i know but I'm doing it on the tightest budget I can and will then upgrade to supported rail etc when I can afford it.

Poor workman blames his tools :whistling:

Well they're not my tools...but will put an order into RDG for some new ones....unless one of you two fancies giving me a price for making the bearing holder????
