I believe what I am going to do is buy two 2.2 KW Water Cooled Spindles. I have the advantage that I do this as a business so it will be a tax deduction. Set one up on my small CNC and the other on the outside of CW. Mostly to proof of concept. I already know I am getting a bigger CNC to do wood in a year or two and will then move the second spindle to the bigger mostly Wood CNC. I will need Tim's Assistance to make a adapter to drive the flex.
