Currently I am using batteries, since I don't have a big enough transformer or power supply to run that motor.
One option is to get a toroidial transformer, such as one of these:

Alternatively it may be possible to put multiple cheap computer ATX power supplies in series to get the desired voltage.

Bravo!
I just started doing something similar.
Only I chose a ER11 C8 L100 spindle. When I got the bearings, I discovered why the spindle was so cheap! The shaft is not parallel. The spindle falls into the bearing with no effort at all. 8.00mm at collet end to 7.93mm over the length.
These spindles must be quality rejects. Thank God for adhesive!!.
I found a bloke in New York who makes spindles for PCB mill & drill. http://cnconabudget.com
You'll find detailed photos of the parts -- makes reverse engineering so easy.....

hi all, ive been following all the diy spindle projects here with interest. a quick Q' do all of you run BESC's for your motors? ive been looking at hobbyking but their units dont seem to specify as besc or standard esc.

As long as it's an esc for a brushless motor you're ok. If you're running it from the same power supply then a normal one is ok else if you want to run it from a separate 5V supply you'll need an "Opto" one.
