    Yee-haw! Er... In reverse? Anyway, don't need to go that slow except for creep feed. Don't know if I will try it out or not. The main point I was illustrating was that the stick/slip definitely did...
  2. Got her back together. New slowest creep rate...

    Got her back together. New slowest creep rate after oil flaking is about 0.1 FPM, or about 1.2 IPM. Nice. The factory spec'd the lowest table rate at 5 FPM.
  3. Hmm, further looking back and forth through the...

    Hmm, further looking back and forth through the individual specific pages of the parts manual for the hand cross feed machines and the power cross feed machines leads me to believe that the diagram...

    So Halco... Any way you could look up under your Techmaster machine's skirt and see if you have a lube Iine in this block where mine has a plug? If it does, can you see where it goes for me? The...

    Yeah, I will add it to the list, haha. I also noticed that there were alignment dowel pin holes under the impostor retainer, but none in the retainer itself, so it's definitely not original.
  6. The current retainer is symmetrical. It's...

    The current retainer is symmetrical. It's misaligned the same no matter which way it's rotated. It is definitely not the original retainer - paint color doesn't match the rest of the castings at all...

    Good thing I pulled the upright. That one oil passage was completely blocked.

    Yep, I'm pretty sure I found the problem, and it's definitely the splined shaft binding. I removed the shaft and checked it for runout, it has less than .002" runout across 5 feet of shaft. That sure...
  9. Thanks! I think I may have just found something....

    Thanks! I think I may have just found something. I'm not sure if the stepper motor in this machine is original... I was poking around with the splined shaft that goes from the stepper to the hypoid...

    Certainly they aren't pristine, but there's no real discernable wear... The unworn areas that are original ground finish as far as I can tell are no different in height from the areas that "look" a...
  11. Well, pulled every lube line today. Pretty much...

    Well, pulled every lube line today. Pretty much every single metering valve was clogged with nasty funky junk. Looked like miniature sump livers from a coolant tank that hasn't been cleaned in too...
  12. It's been some time since I read Machine Tool...

    It's been some time since I read Machine Tool Reconditioning but I remember there being something in there about the hydraulic grinders that use the same system for hydraulics and lubricating oil -...
  13. No they are not, but I'm not sure they should be...

    No they are not, but I'm not sure they should be with continuous pressure lubrication. I think they just kind of float on the oil. I can't even feel an inkling of wear between where the surface of...
  14. Yes I sure do have multiple manuals. The only...

    Yes I sure do have multiple manuals. The only problem is that this Dial-a-Size option seems to have been somewhat of a rare bird on this size machine. So the parts manuals aren't exactly always...
  15. So got into the cross feed cylinder today. Found...

    So got into the cross feed cylinder today. Found that it doesn't contain any piston seal at all. It's a metal on metal fit from the piston to the bore. There's a seal on the rod, but not on the...
  16. Well crud. I got the valve blocks all...

    Well crud. I got the valve blocks all disassembled and cleaned, made a few new gaskets, put everything back together. Didn't solve the problem. On a positive note, all the spool valves looked to be...
  17. I think the table dogs can do that in manual...

    I think the table dogs can do that in manual mode... Not positive though, I have only ground the chuck and one part so far. Will check when it's back together. Anyone else have a Series II or used...
  18. I don't think it does. Only the table dogs. Would...

    I don't think it does. Only the table dogs. Would have to add that.
  19. Specs say minimum longitudinal auto travel rate...

    Specs say minimum longitudinal auto travel rate is 5 fpm. I haven't tested it to say for certain. I'm sure it could be set lower with a tweak or two also. Throttling valves in the table cylinder...
  20. Plunge grinding is definitely faster, less wasted...

    Plunge grinding is definitely faster, less wasted time. Like you said earlier, just need to monitor the wheel wear a little closer. Have you ever run a creep-feed grinder? I've read a little about...
  21. Yep. There's a selector for "Slot" or "Surface"...

    Yep. There's a selector for "Slot" or "Surface" on there. Slot can be set to downfeed at either left side, right side or both sides. And yeah, coarse downfeed can be set anywhere from .0001" to...
  22. Yep, 2 HP direct drive. I will definitely try...

    Yep, 2 HP direct drive. I will definitely try that after things are back together. Got all the bits out right now looking for any issues. Added a closer up shot of the controls too in case anyone...
  23. Yeah I should have thought about that actually...

    Yeah I should have thought about that actually since I was having trouble with the cross feed... Would have probably saved me some time and aggravation.

    I ended up whacking down .001" at each end...
  24. As far as holding better, after the chuck was...

    As far as holding better, after the chuck was ground in I set the dresser on top and turned the magnet on, then tried my darndest to move it. It didn't budge at all with all the force that my 210...
  25. Yep, I've never bothered relieving the...

    Yep, I've never bothered relieving the separators. A light dusting cut on the finish grind of the chuck with an open free-cutting wheel dress and loading isn't a problem. If someone tried to grind...
