Hey,
Runout seems very good but I havent tested with a dial indicator yet. I plan on checking it after I mount it on the router. A lathe is a must for this kind a project. Every piece was machined on my crappy Harbor Frieght 7x10 lathe. Cutting stainless really SUCKS!!! I killed a bunch of carbid bits. Its also really hard keeping the run out 0 when using the lathe. A steady rest is also very important.
I do use mach3 (just the demo for now) and havent really thought about trying to controll the rpm. I do want at least controll spindle on or off though and to be honest I havent even gone down that road yet. I forsee problems with a rc brushless conroller though. In order to controll a brushless esc you need to use a servo tester. Its a device that emulates the pulses created by a rc reciever. Im sure it could be done but it would uncharted territory. For now just using a relay to controll the power supply will be good for me.
Saddly I always intend to document my builds but I always get cought up in the build. Then its to late if you havent taken pics the entire time.
Like I said before, none of this is an original idea. There are a few threads I have pointed out before that have every bit of info I used to build mine.
Look for any post from herbertkabi, that dude has really figured out the hard stuff.
Read this entire thread!!!

That thread is chocked full of good info. Also read as much as you can about Angular contact bearings. Before I started down this road I really had no idea how complicated mounting bearings can be.
Have fun, I will add more pics after I get this running a 100%
