    Hey Gang,
    Have a little update for a few projects.
    Welcome to all the extra visitors c/o WillO from hackaday.com.Thanks guy.
    That's a really cool site more for the electronics side of things.
    Will be getting my own website up and running soon thanks to Godaddy.
    Will post a link when she's ready.
    Here's some pics of the spindle lock I made. Had to mount it on the front
    to make room for the attachments that go on the right side of the Mill.Changed the length of the pin so it doesn't protrude as much as in the first pic.The print shows the shortened pin.
    Also some clamps to hold down a precision vise.
    Plus a sneak peek at the surface grinding attachment.Waiting for my grinding wheels to show up from Wholesaletool.

    BobArt Pro-X does this quite well. There is a demo version builtin to BobCAD too. I ponied up and bought is as an addon on one of their slow sales days...

    Short, you can open any supported image format and do posterization from 2 to 8 colors IIRC. You can vectorize in multiple formats too. It makes a vector toolpath out of an image, the rest is just a few clicks away.

    That was a neat feature, one I thought I'd use, but it's the embossing feature of toolpaths that I've used the most.

    Looking for a cheap Flycutter?
    You could make one like I did.
    Here's my print.
    I use a single Kennametal Carbide insert CNMG431 KC850.
    Get them here.
    http://www.jlindustrial.com/catalog/...tosearchpage=Y
    Or a lot cheaper on Ebay here.

    I hold the insert with an allen head screw.

    Even though this is highly off topic, KC850 is the grade of the insert. That doesn't describe the geometry or size. It looks like you were using a CNMG insert, probably a 432 or 332, the most common sizes and radii.

    Hoss, I'm considering following your plans and am working to understand them in depth. One thing that is eluding me is the use of all the parts above. Specifically you specify two (03381142 1.250X1.937X0.032 THRUST WASHER-NEEDLE-FLAT (2)) thrust washers. However in the z axis mount.bmp you only use 1 ("thrust bearing i.d. 1.25 o.d. 1.938 width .110). Where is the second washer used?

    Secondly, I think it's safe to assume that you did not replace the bearing assembly on the X-axis. Other than that I think I have it

    Finally, did you buy a 15/16 - 16 tap?

    Jay

    Hey Jay,
    In the original setup. I only used 1 needle flat between the thrust bearing and
    the aluminum mounting plate, but added a second one on either side of the bearing to give the bearings a hardened surface on both sides to ride on. I
    figured the bearings might wear into the lower flange since it 's not hardened steel. This cut down on the amount of shims I needed to just .005.
    The shims just compensate for tolerances of the machined parts.The shaft of Flange C could be left a little long initially (.050 maybe) and faced to size when all the parts are put together instead of shimming. Like I always say, It's easier to remove material later than try to add to it.
    You assumed right, the X axis bearings are stock.
    I did get an import 15/16-16 tap at wholesale tool.

    Hey Greg,
    If I come up with an auto tool changer, I will certainly show it off, but I haven't started anything yet. I downloaded a pdf from Little Machine Shop of the one they are selling for $1000.
    http://www.littlemachineshop.com/pro...gory=879658189
    Looks really cool, but way too much for me to spend on something I really wouldn't need unless I got into making production parts to sell.( like maybe a kit for an auto tool changer, Hey maybe someday)

    Hey Gang,
    Had a problem with the X2's circuit board so I was looking for a replacement.
    Didn't want to spend $99 at Grizzly or $120 at Little Machine Shop.
    http://www.littlemachineshop.com/pro...211&category=6
    I found a 130 VDC 8 AMP MOTOR CONTROLLER BOARD used in treadmills for $30 at http://www.surpluscenter.com/item.as...tname=electric
    It works just as well as the original, even have to cycle the power switch(4.7k Potentiometer) back to zero when you hit the E-stop to get the motor to come back on just like the original. The schematic for the circuit board calls for a 5k Pot to vary the speed but the 4.7k on the mill works (just shuts off a little slower than before.) Use the E-Stop to be SAFE!
    Here's some pics
