Hi All,

I am inspired to build my own bench top cnc mill, but I am concerned it may not be a realistic proposition. I want I high precision machine with the capabilities of cutting steel if need be. I already own a HF45 clone (Hafco). I considered initially to convert this machine but I'm put off by the dovetail slides, variable build quality, stability etc.
I mainly want to machine aluminium, but the odd bit of steel. My desire is to make go kart type parts like bearing blocks, spindle parts etc.
Is it more realistic to just buy a Minitech 3/4 (or equivalent) platform and add parts as I can afford them. I have a friend who is on this forum that can assist with all the control systems. I don't feel like dropping $3k + on ground plate, rail, ball screws etc only not to realistically achieve better than 0.001" tolerances. So, can it realistically be done or am I better off just to save up and buy something?

Many thanks in advance.
Rob
