    I don't have the chart in front of me. But I'm almost sure that the 80 tooth gear is used as an idler (i.e. transferring the motion directly to the next gear, not keyed with a second gear to change...

    To me it looks like in decent conditions. I don't see where the foot is broken. Anyhow, you'll spend much more money in getting another 9" than scrounging/making the parts that are missing in yours....

    I'm sorry, but I still cannot understand why.
    For helical milling you that the projections of the axis of the spindle and the axis of the dividing head intersect exactly at the cutter.

    All this...

    I have enjoyed this video like the previous ones.
    The only partial criticism I'd make, is that, given the fact that the bearing pads are fairly short both on the bed and on the gap, personally, I...
  5. Well, it would be irrelevant on a universal mill,...

    Well, it would be irrelevant on a universal mill, since you orient the X axis. Therefore It isn't anything intrinsic to the machine.

    Similarly to TGTool, I have hard time imagining any operation...

    Moreover, nobody would prevent you from widening the central T-slot in the opposite direction, to bring it back to center, if you really want.

    That just happened, in complete demonstration of what you're saying: the widow didn't want to pay the rent of the place for one more month and offered the 10EE and a pallet jack for free to a friend...

    You're rather changing the shape of the part, not much the size. And, in certain cases, you would obliterate the part by using a cutter larger than the stylus: think about a trigger guard, where you...

    Just a couple of comments (I think we have touched already most everything essential, otherwise)

    1) Sharing a VFD between machines: I second the general feeling that it is better to have dedicated...

    It looks better and you can see that you're starting to develop a checkerboard pattern.
    However, I do have the impression that your scraping marks are still on the shallow side. If you have a tenth...

    Mark,
    Just a couple of comments.
    I have the feeling that the scraping marks are fairly shallow (and I bet that the spots start shifting around from one bluing to the next).
    Second, I suspect that...

    Steve,
    Could you measure how much power yours uses in different operations (including idling), vs. the rating of the motor? Possibly this piece of information would give the definitive answer to...

    After having sprayed a lot of penetrating oil around the nut, I would position the spanner wrench so that the handle would stick out at approximately 90° on the operator side and apply significant...

    I have hard time to see enough details from your pictures.
    The first lathe is a relatively early Hardinge Cataract "split bed" second operation lathe with a turret tailstock. I am not an expert in...

    Nice paint job and general cleanup.
    From the video I couldn't determine if the replacement bearings for the spindle were just ordinary bearings or high precision ones. However, by hammering them in...

    Two considerations.
    1) Bearings: the aren't necessarily shot. It could well be that the grease has dried out and is now too hard and too viscous. Possibly, you can get a few extra miles out of them...

    Todd,
    I'm not sure if I understand what you're looking for.
    The lathe at Mueller I believe has a Multifix toolpost (Multifix Toolpost)

    The major challenges I see with your machine is that it is a production mill with a rather short table and rack and pinion, instead of a leadscrew on the long axis.

    For many jobs, these aren't big...

    I agree with the other comments that this is a minor issue.

    Perhaps I'm stating the obvious. However, my suggestion is to first evaluate if everything important (and expensive) in the machine...

    The motor shouldn't trip the GFCI, independently of the load. What could happen is that it takes longer to come up to speed and, possibly, that's enough for the starting winding to heat enough to...

    Denis,
    Personally, I would cut the taper significantly steeper than 1°. Consider that, with a 40 TPI screw it is fairly easy to adjust to 0.0001" (i.e. micrometers). A ten fold improvement on that...
