Diy Brushless Spindle

[njhussey]

Look for motor with 1/8" shaft, buy 1/8" shank cutter, replace shaft with cutter...

Cheers Jonathan, I looked at that but I was looking to do one if possible where I can change the tool without having to remove it from the motor. I was having a look to see if there was anything out there like a pin vice that could be used but thought I'd float the question.

I've got a Proxxon E50 that I was originally going to use but thought I'd go back down the brushless motor route.

You might be able to do something like drill and ream/bore a 1/8" hole and hold the cutter in with a grubscrw. The force on the cutter will be very small, so it should hold perfectly well.
