Just pointing out some ironies and not trying to be crass as I understand some people like to tinker…
For anyone who has thought that a spindle/VFD is too complex or expensive, I challenge you to read this entire thread and maintain that opinion 
.
And if anyone is wishing for Makita to “enter the market” with beefier bearings and lower RPM range just slap a Makita sticker on the side of a spindle and boom, all the features desired 
, less runout and Bob’s your uncle .
Just some food for thought…
