TP grinder take 2

Thanks

Would the bearings of the previous design not be more accurate and longer lasting than the motor's?

I want to build this only once, but do not think I will ever use it as a mill, just a griftnder.

Dear gn
Bearings technology has come a long way, but you get what u pay for. I did notice the bearings in my current motor looked similar to the ones in the shaft in my first so I guess a decent motor runs decent bearings. (they were both sealed) and If you run er16 collets in your grinder the the option to mill or drill is always there, so maybe there'll come a time...

All the best
