I have an old Tree Journeyman CNC knee mill that is a fantastic candidate for a retrofit. With the help of a local friend, I am learning about all the different components that I will need to take on this project. Thus far, I've been sniffing around fleaBay for servo drives, a VFD (for the spindle), and some encoders. Is that the best place to find stuff on the cheap? Obviously, since I'm doing a retrofit, I don't have boatloads of cash to throw around.
Anyway, if eBay is the best place to find such components, I'll keep looking. However, I figured I'd just post something on here to see if anyone has any pointers (or parts they'd like to sell). Thank you for your time!
