    Impractically quick! (and dangerous!). Usually cut wood between 5 and 20 depending how deep. Bellows came with the unit (Isel), 20 years old now. They are actuall just folded with U shaped thin plastic formers glued in the folds.

    Me again

    I replaced the 20mm linear shafting and it certainly tightened it up.

    Replaced the X, Y ball screws and doubled up on the nuts to add a 1kN preload :naughty:

    The ebay M8x.75 half nuts I bought on Monday haven't arrived. Can't thread the ballscrews 'til I have the nuts or it suddenly becomes guesswork for the length and die closure.

    A very nice man at bellevillesprings.com gave me half a dozen washers to preload the thrust bearings. Their 15 minimum order translated in to 150 pcs :whistling:

    The metal for the splash guards did arrive so I will probably start on that.

    Pic is the bed and saddle upside down.

    I've extended the table 2" forwards with a lip. Then I decided that driving my Warco mill using MSDOS was a right PITA after seeing what Windows 7 can do with this thing.

    I have the new software about 80% complete so I'm going to do that before I cut the splashguards. It takes a DXF file, converts it to a cut and then drives the mill.

    Back in a few weeks, if I don't get sidetracked again :whistling:

    Me again

    Splash guards fitted and looking a bit '70s retro.

    An IP65 sealed box bolted to the right hand end is the suds tank, I'm using the Tee slot as a gutter.

    Next, sealing it with gasket compound and cutting some slots in the bed so I can fit tee nuts from above and improve the drainage.

    You asked me that before, you want me to be more specific? :naughty:

    Specifically, I plan to cut Alumec and make injection tooling.

    Alumec is a sort of improved 7075 T6 alloy in 3 grades which can hold a deeper temper. Get it from Blackburn metals.

    Hi Robin,

    I have an old PNC3000 at home, used it few years ago but EPROMS seem to be dead now (25 years old...).
    I understand you have reprogrammed yours, and I would like to give another life to my machine.
    Do you know where I can find the original EPROM content?

    On the longer run, I would like to replace all this venerable electronics with a Raspberry PI + some kind of controller board (the one used on 3D printers or a custom designed one, linux enabled if possible). Do you know about such initiatives?

    Many thanks for your help

    Kind Regards

    Jean

    Hi Robin Hewitt - Can you please tell me the actual manufactures part numbers for the DC Motor and the ER16 spindle you placed in your Roland CAMM3 PNC-3000. Additionally, can you please provide me both pulley part numbers along with the belt you used.
