  1. All that aside 8 micron is bloody good for an home made jobbie. I know i know its only a quick sim and there are a lot of variables that that can influence the end results but it goes to show that it will be more than enough for cutting most things a hobbyist will want.

    just to show you all what I have made before, then here's a pic of my last machine.. ;)

    On the next one, put the Z-axis rails on the plate that the spindle is attached to since that way is stronger as you're reducing the overhang.

    Yes what he said and paint it black because white gets dirty too quick.!!. .

    Yeah, the rails will be mounted on the moving plate on the z axis this time. I also found the other way to be less effective, although it did the trick as it should.

    Well, it's been some time since I updated this thread. And A LOT has happened... :)

    The machine is in fact ready to go. All I need is dust extraction. But that will get there when it gets there.

    And I have done some cuts on it already, so here's a few photos for your enjoyment. :)

    Excellent looking machine, I like the simple base design and how it can be adjusted at each corner but does it vibrate, resonate ?

    There's very little vibration in it. Especially after I added the 41mm MDF top to it. 22+19mm MDF.
    Plus I added extra stiffness on the crossmembers with 60x60x4mm steel tube.

    I have done a cut test in Aluminum, with a rather agressive cutting parameter, and it came out lke this, with a single flute cutter. You need to look at the area within the red rectangle.
    The cut was done rather agressively, and with a 3mm single flute cutter at high RPM. Will go for a slower RPM next time I try it. It looks bad looking at the picture, but the cut is actually very flat and smooth.

    I once looked deeply into making loudspeaker cabinets (big ones) and it was deemed a good idea to use a glued sandwich of MDF and plywood to reduce cabinet resonance.

    Laminating sheets is always a good thing, it does remove alot of resonanse and vibrations all together... I had hopes to find another 40mm bottom sheet this time, but sadly I did not find one for cheap this time around.
    But the overall look of the machine and the precision is more than ok for my uses. Which mainly will be woods and plastics, and perhaps a bit of aluminum.
