RC Brushless spindle

[volcano]

Hi njhussey,
Thank you for very welcoming replay and advices about my purchased stuff, and this "ghost" subforum. I think i stick here for a little bit. Maybe some other folks will stepp in.
Still, i`m very happy and honored to speak with you. As i said before, i have been read all your words about this topic.Excellent!

Edit! Ha...i was right about sticking here!, Hello Lee Roberts! ( as i write this , you stepped in) Nice and thank you!... and Yes i purchased C8 ER11 L100 + pair of 1/8'' & 1/4'' spring collets.

I need to buy bearings... (thinking about ABs or cheaper roller ones... still don`t know) and to see what to do about PSU.
I was thinking about "pusher combo" (battery+ psu)...
Then again, i saw some HP server ps.I t`s is 12v 100A 12000W! And its cheaper then bottle of vodka :-).
But there is 2 catches. First, shipping to Eu is ~$50+. Second, 12v for my motor is not very fast solution ( 12x380kv=4560) as i understood.
I want of this spindle to be more "universal" for now. So, something at 24v...is what i`ll look.
Please fill free to guide me in good direction !?

As for whole spindle design, the body will be the same as you done it + some alu ribs around body.
Extra electronic will be some hall sensor for rpm + arduino + display and to second "main" arduino( grbl1.1) for pwm control.
I do not have any of the items yet ( except "main" cnc electronics ), as they are somewhere at the road.

That all is in my head only, at the moment. So there will be pics soon as i start working !
What stepped from my head to reality for now is this desktop router.It`s a small but very rigid little thing. It`s about 70 kg total weight,
and it`s a 90% mechanically done. I`ll have some z work ,as you can see, then some paint job, plastic covers, cabling, makeup (maybe not :-) )...
Here are the pic.(sorry my spare phone is terrible, broke the real one week ago :-( , hope i`ll get new one before spindle build starts ).

P.S.Sorry for a little off topic, F the router, lets make some SPINDLE!
and..sorry for my a little "better" then google translate, english :-) .

It`s not so hard to learn slavic as we use a lot of hands/guns in our conversations. :-)
I`m just kidding, people here, are very polite and friendly!
Cheers!
P.S. As this is off topic , again... i`ll edit this (after you read it) into something useful for future spindle build! :-)

Edit: What are you think about my spindle conception ?

Lee said that ppl here love pictures...
So here they are... :-( , but not happy ones.

So... motor come today. I was very happy, but my happines lasted for about 10 sec, and then pufffff...

Update:motor returned.
Looking for new one... 500-600kv.
Any suggestions?

The kV of the motor you need will depend on the Voltage you're going to run it at and what you want to cut.

Hi, tnx for replay,
I want to cut a little of everything (alu, pom, mdf , some glass etching), (Glass isn`t obligatory - i can do it with my dremel tool @ 20000+ rpm). So... first alu , than acetal and mdf.
I know that`s hard to do with one motor, but hope it isn`t impossible.
Now as i`m not "bound" to previous motor specs, i would like to go "around" and start with psu i`ve got already- 12V30A. Read here that similar psu-s are already used - not for max motor efficiency , but still, for something useful.
I`ve heard that 24v cause hot motor ( and i have 24v@4-6A, only)
So if i go with this cheap psu what can i drive with it?
Some other suggestions?
Cheers!
P.S. They say that i can keep this 270kV. Any use of that thing (if it works- i have not tested it yet as i don`t have esc and servo tester yet)?
