    So this is my Warco Knee Milling Machine. Just as a project I would love to convert this machine in to a CNC Milling Machine and hopefully make some money off that machine or just use it for projects. I have now had some experience in constructing the electronics after building my custom power supply for another custom CNC router. I know i should convert the leadscrews to ballscrews however money is tight so Im gonna expect some inaccuracy. Im pretty comfortable on how I will be attaching the steppers and driving the axis', however Im not too sure what size motor to go for. I know that the three main contenders would be the Nema 34 or 42 or just not going for a stepper at all and going for a servo. However, as I have already mentioned this is a project and not a Job therefore money is tight. I have found a good kit for the Nema 34 with DM860A drivers and 60v/350watts power supplies at a really good price. Im slightly concerned about the holding torque. I know that the handwheels on the mill atm are easy to turn by hand so I guess you don't really need much holding torque. Any suggestions on the size of stepper would be wonderful. I don't wanna make a mistake buying inadequate steppers.

    Also any suggestions on good suppliers of timing belt pulleys in the uk or aboard (with cheap shipping) would also really help.
