    My mill is about 3 years old and used mainly for making clock parts, the reason for converting to CNC is to speed up the cutting out of clock wheel's and plates and to move away from cutting by hand with a fretsaw.

    I am using the original lead screws but replace the cast iron nuts on the “X”and “Y” axis with Acetal nuts made to the method described by Evan Willams.http://bbs.homeshopmachinist.net/thr...s-the-easy-way.

    The backlash with the new acetal nut for the “X” and “Y” is X =0.08mm and Y=0.05mm, on the “Z” axis I have fitted a gas strut to control the weight of the head which also looks like it is controlling the backlash, but I will see how it works in practice before making any more modification.

    For software I plan to use FreeCad > HeeksCad/Cam > LinuxCNC.

    Next phase will be to buy the stepper motors and controls, which will be in October due to Holidays.

    How is the machine in general ? I have just purchased one with intention of converting it to CNC ?

    The mill is very good and well made but its best if you re-grease the head and lead screw bearings as the quality of the grease used is poor. The main weakness of the machine is the DC drive motor I am on my 3rd and I don't use the mill for heavy work, I have improved the cooling to the motor in the hope of solving the problem.
    Hope this helps Steve

    Also could you show me a picture of the table size, I've seen SO many different size tables but I would like the longer one. To get the CNC Kit it needs to have the long table or the ballscrew for X will not fit. In the sale advert it says 500/700, what the hell does this mean :D is it 500mm long or 700mm long ?!?!?!?

    Hi Ian, sorry about taking time to get back to you but I am out of the UK with very little internet, I think the 500/700 is the difference between the standard which has a 500 mm long table and the LV version that has a longer table at 700 mm.
    I have the LV machine, I found that to fit a ball screw on the "X" axis you will need to machine a space for the ball nut to fit in as it is all very tight for space, when I get back to the UK I will send you some photos.

    And it's here !!!!

    What a tool this is. Honest to god it was worth every single penny. The machine is so much better than the other one I had it is just not comparable !

    The only thing stopping me now is the clamps I had for my vice will no longer fit because the new machine T-slots are wider so they just won't clamp down. I'll need to buy a much bigger vice as well so nothing goes anywhere :)

    Here is the package I took delivery of before work: it was 175KG !! Nearly killed my self getting it into my garage !

    And this is its new home, my dad and I with a combined weight of around 34 stone jumped up and down on the table with no issues. If it can withstand 34 Stone I'm sure it can handle roughly 19 stone :)

    I will be accepting machining work as soon as I sort out a new vice.

    Please comment if you wish about some upgrades and what not :)

    Congrats on the new mill
    I have the next size up machine with the large table and find it does everything I need to do
    however one fault with mine was the gearbox selector between H and L had a detent which didnt fully engage the plastic gears so after a short time one had stripped all its teeth off. I fixed the detent after that but its still a good idea to make sure the knob is turned as far as it will go so making sure the gear is fully engaged.
    Mines still manual in operation but i've fitted motors to the z axis and a power drive to the x axis

    Ah cool. My next plan is to design the lay out of the monitor and electrics etc... But first I shall make up all of the electrics and then get a CNC Conversion kit and get the ball screws to suit
