    Unless he is in a machinery desert, the price sounds like a lot of wishful thinking.

    The only good news is that, being completely apart, it is easier to move. The very bad news is that you don't...

    One more vote against liftgate truck, unless you have a lot of experience: the liftgate it's at an angle fairly close to the tipping point of a mill, especially with the motor overhead.

    ...And, if you do not own the hosting website you risk similar problems as with Photobucket, or Picasa (suddenly ditched by Google).

    Given the short bed, relatively small spindle hole, and everything else noted, if bearings are in good shape and there is no excessive wear in the ways, the price seems a bit on the high side. these...

    My understanding is that the backgears remain in mesh, while the spindle is sliding out. I think that the relative movement back and forth of the bullgear during disassembly is at most 1/4"

    The main reason for jogging (or, in the case of VFD, to ramp slowly up to speed) is lubrication. Plain bearings need to have a proper film of oil to operate. If you spin the shaft too fast without...

    I'm not sure if you're serious or you're just pulling Coffeetek's leg.

    You might know the seller. However, the paint job doesn't induce any confidence (I'd expect anybody at least partially...

    In reality, there are/were two main reasons for forging, one being forming the correct grain, the other to reduce to a minimum the need for machining, therefore reducing drastically production costs,...

    Hard to say without a better description and more pictures.
    If only the central foot moves, I'd suspect it's a sort of radius gage (i.e. measuring the radius by three contact points Possibly, it...

    A clarification: all complete combustion of any gas or hydrocarbon in general produce CARBON DIOXIDE (CO2), NOT carbon monoxide (CO).

    With my Chinese 150 grit resin-bond diamond wheel it takes probably slightly longer than with a green wheel, but definitely not so long.
    Are you sure that the surface of the wheel is not clogged...

    I think it helps at least to not digging grooves in the wheel.

    I see it more useful when sharpening a lathe tool/indexable insert to a specific geometry, but it also works well when freehanding.

    If you insist in using a green wheel, do yourself a favor: bring the grinder outdoor, wear a mask and Tyvek suit or clothes that you can throw away after the (extremely messy job).
    A few years ago I...

    Generally people (myself included) prefer to use a diamond wheel of some sort run at lower RPM (~200-350), since the rate of material removal is still decent, it produces much less heat, and it is...

    I don't understand much from the pictures. Were they the two bolts/nuts I indicated in post #7, or was it something else?

    It's kind of puzzling that they'd be using two T-slots, one on each mating surface, unless their arcs have different radii: the "strong bolt" on the front would use the T-slot in the saddle (not...

    You might argue that it's mostly matter of semantics. However, when the current carried by two conductors is in opposition of phase, it is considered a single phase, with the ground in the middle...

    Removing very little material, especially if the machine is not very rigid, is a big challenge, even using abrasive wheels (generally, you do not have enough rotational speed in a mill spindle to...

    I'm wondering if, instead of bolts, some are cams, like on K&T and other universal mills.

    What about the two "nut-looking things" circled in the picture?

    I'm not sure about what you mean with two phases. but that plate looks like a single phase motor, requiring a starting capacitor. Two phase distributions are fairly rare. In the States I am aware...

    Jim,
    Still you aren't answering our questions.
    1) Where are you measuring the TIR (a couple of pictures would help)?
    2) If you put a mark on the chuck where you have the maximum reading, remove...

    I am not sure as well if I understand the problem correctly or not.
    First, I would check if the run-out is repeatible in position and magnitude with separate mountings.
    Second, I would test if it's...

    I would say definitely not more than 4000.

    When you move it, I strongly suggest you remove the overhead motor first. If this is not an option, at least widen the base by bolting the longest pieces...
