Hi Folks! It looks like I'm going to lose my extra work space come spring so I'm posting this now to see what if any interest there is. I hate to part with it but I just won't have space and it seems two mills is one too many : )
It started life around 1919 as a Horizontal machine. I did a tool refurb post on this site so if you hunt you can see what I started with. This little mill is kind of unique in that originally the table was run by a rack as wasas a 4" Z adjustment. At some point it was converted to a vertical head (Halco) that had a B & S 7 taper arbor and a 1/3 hp motor. I converted it to DC and 800 watts with a tooth belt drive and drove the spindle 1:2 to give 2500 at the spindle with infinite control on the Brass knurled knob(just halve the readout), The red knob is E Stop. The DC unit has reverse available, a bit clunky but once you've done it a few times it's quite quick. I also converted the spindle to R8 using a Bridgeport clone spindle and proper precision spindle bearings replacing the tapered rollers it was built with. It has power x with about 10" of travel ( there's another 3 ish available with a small modification but I was worried about table overhang) and manual y with 4" of travel, the total Z is around 14" between the knee and the Z rack there is also 4" of quill travel on a worm gear setup (very nice for drilling). There is DRO on all axis, x,y,z on the big DRO readout. The Quill has a stand alone. I also added a gearbox to the head to make rotation more controlable. It has approx a useable 45 degrees in both directions but cabling will inhibit the travel in one direction. The stand gets it to a comfortable working height and has levellers on all feet. As you can see there's a ton of hours in it that resulted in a really versatile small mill,( the foot print is 36" x 36") hence my reluctance. If you're interested contact me we'll talk and see what shakes out.
