Taking this route for spindle

[GeorgeD]

I'm looking to use this senario of spindle drive rather than conventional kress/water cooled spindle.

It will use the (ER) type chucks and collets which will multiply the use of different bits rather than only have a limited tooling option using a kress ect,ect.

I have a brushless motor at hand,in the process of making a pully for the motor but don't know what size (ER) chuck to go for yet?

Whats the pros and cons of this type of set up? :tup:
