**volcano** · 09-05-2017

Hi all!
I decided to join this forum as i was inspired by member "blackburn mark" topic here. Genius idea !
I have read this topic completely , and decided to build my own. Purchased some stuff already.
I`m not 100% sure what i buy

P.S. I am planing to buy another faster rc outrunner motor for woodworking in future. For now, i`ll be pleased to solve this "combo" :-)

Hi there! All those components look good to me. The motor is the same size as mine and the other bits look fine. How are you powering the spindle? Any details on how you're doing the body/bearings yet?

I've not been on here much lately and you'll only get people answering you if they know about the topic or feel they can offer advice. Blackburn Mark doesn't come on here much anymore and the other person who used to contribute to that thread, Jonathan, is busy at Uni and doing E bike racing. It's also easy for your post to slip down the "Trending Now" tab which is what most people see, I certainly don't often look in the Forum sub-forums unless I'm looking for something in particular.

Good luck with the build, look forward to seeing your progress

Hi Volcano welcome to the forum!

Neil covered everything, Mark is/was available via PM or email if you need to contact him.

Dont forget you also need a straight shank ER11 collet holder:

Your right it is a great idea, I hope to make my own too, first I need to buy a lathe lol

Good luck and dont forget to post your build log for it (we

pictures)

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 ).
