    Dan,
    Looks like not much left of the original machine but the bench,base casting and mill table. What did you use to make all the parts? Looks like a great build if you could post some more details on all you have done. Got a kink in my neck trying to look at the one picture.

    As you can see I used the lathe headstock spindle which has a MT4 taper you can find collets on ebay they take a 1/2-13 drawbar. I achieved more possibilities with this by mounting the lathe chuck. I have a HF spindle that I can mount on the table and use the main spindle as an A/4th axis.
    As far as making putting this project together. I used a craftman drill press, a magnetic drill press and a surface grinder.

    great job, so what is the other milling machine you used to build it, like instructor37 said not much of the original machine left. The only thing that looks similar to my 1991 shoptask is the green vice.

    This is interesting and deserves a full build blog, one photo is not enough for me.

    I stayed more loyal to the form factor, taking a Patriot removing all the bondo, paint & grinding the castings more accurate to their intended shape, powder coating everything, dual balls screws gas springs, & on & on.... I even bought a Biax scraper to finish out all the bearing surfaces, almost 6 mos. I spent doing just that!! My wife thought I was nutz when I brought the surface plate, scraper, & the saddle in the house because the garage was simply too cold.

    I like your angle of attack better though.

    It looks like for you ways you're using linear rails bolted to a bed, is the bed the original casting or is it something new altogether? Are the vertical ways the same as the horizontal ways? How did you avoid deviations where the linear rails are bolted to the casting? Sorry got a million questions in my head...

    I did use the original bed and put it on a surface grinder as with all surfaces I bolted rails to. All surfaces and bearing mounts were ground to .00005 in flatness. The vertical rails are designed for vertical mounting as the horizontal rails are for there intended use.
    I spent 2 years finding parts on ebay and 2 winters doing all the work. It will hold .0001 accuracy full travel on all 3 axis. I still have quite a few things to do to finish but for now it is operable. With summer here I dont have the time to finish so it will be fall/winter when 100%
    The rails are THK 35mm and 25mm. The ballscrews are Kuhn swiss 25mm with 5mm pitch no backlash.

    LtDan,
    I think we are ALL patiently waiting for your build log or something...
    Now I'm not rushing you or anything but I will say it's been over a month now since your last post...

    I'd imagine some of us may start yawning before long...
