Lighten up,Ross...I was only jesting.
I know. how about this??

Sorry, this is the blind leading the blind unless some has actually done this . .
Thanks Steve....... I Wonder if I will ever get this working..


I asked about balance because the spindle I bought had balance holes in the collet nut. It's another step towards a more refined and accurate machine.
Not the dreaded vibration stuff again :naughty: there is a version in my mind that inverts the motor so it is parallel to the spindle and mounted the opposite side of the y axis gantry but running the opposite way to the spindle to cancel out the inertia (not sure of the terminology)........

Maybe you're beating yourself up a bit there with what you might achieve,
yeah I'm under no illusion that I can make a super accurate precision spindle that can run 24/7, but I would like to have a fighting chance of making a decent home use one.

I've been looking at the A/C bearings and there are so many to choose from with different angles and precision ratings, I can get a budget one for around £12 but the proper matched pairs can be around £100 or more. I just need to work out if using good bearings will average out my machining skills or if they are a waste of money at the moment.

I can see my self just getting the cheap ones and a few deep groove ones and then just trial and error... if the run out is acceptable and it doesn't flex or chatter when cutting then job done
