    If the machine is not bolted to the base I would not let them ship it. They have tied the machine to the crate at a number of points where I don't think the machine should be stressed and is not...

    Hi Thanos,



    The tailstock will work with either the MT4 or SK40 dividing head, so that I don't need to trade. And I suppose that the chucks will also work with either head, I just need new...

    Someone (John from Portland, Oregon?) sent me a private message about an FP1 (MT4) dividing head which I have, which I want to trade for an FP2 (SK40) one. But I accidentally deleted the message. ...

    Hi Marcus,

    Thanks for the comments!

    It's a good question. I am hoping that by putting the fans on the far right hand side, away from the grinding mess and activity, they will not pull in gunk....

    Still too busy to spend much time on this. Here is how the mock-up currently looks from the outside. Botton fan blows air in and the top fan pulls air out:

    Instructions are in the manual. Have you got a copy?

    You remove the cover from the bottom, unscrew the hoses from the hydraulic pump, and then just pull the whole tank/pump assembly out. Have a...

    There is a part number and serial number stamped on the bottom. Ask seller for that. It is a good deal.

    Hi Tien,



    That last photo caught my eye. I have never before seen a circuit board literally laid out on top of a schematic. It doesn't use space efficiently but it would sure be fun and easy...

    The FP2 looks like a good deal. It appears that the only significant thing which is missing is the Y axis lead screw and the bracket which attaches that to the headstock. Perhaps it was crashed in...

    I didn't like the first version of the cover and threw it in the trash. Now working on version 2. Basic idea is to enclose as much as possible. So on the grind side all that is going to be visible...

    You should have a wrench that's about 250mm/10 inches long and give it a solid tug with your arm and shoulder. Don't throw your entire body weight into it!



    That's also what I typically do as...

    You listed 3 cases above, but not my case (2/3 HP motor with 2 HP drive). Do you agree with JCByrd24 that this is OK?

    Hi Peter,

    Others here can answer your questions better than me. But there is one thing I am quite confident about. You describe how oil can make its way into the spindle via the key way slot and...

    John, one further thought. Is there any way that something could have "smacked" the hex shaft for the X axis table lock on the door side? That would transmit force through to the locking lever and...

  20. Can I use a 1.5kW or 2kW VFD for a 0.6kW load?

    I want to operate a small spindle motor (0.55 kW, 200 Hz, 230V) from my 230V 50Hz mains. So I need an inverter. Here in Germany there are good used ones available at low cost, but for 1.5kW (2HP). ...

    I spent a few minutes looking at possible fan locations. Remember that I intend to enclose everything within a cover.

    I first thought about having the fan as below. The airpath is shown with the...

    0.0003" per tooth seems too thin to me. I usually aim to make chips that are around 0.05mm = 0.002" thick. But feeds and speeds are not my thing, so could be that I am not doing things right.

    That's a nice machine. I suggest that you replace the Y handwheel with one similar to the X and Z handwheels (with a spinner handle). Otherwise it's very slow to crank Y over. If you post the...
