    Rons,

    Thank you very much for you quick and complete reply! I have followed your suggestions, the motor is running quietly, and I have hopes of some years going by before I need to pull it...
  2. HLV-H Spindle Motor: Re-installation and Greasing

    I'm re-installing the GE spindle motor back into my Hardinge HLV-H and I'd like advice on installation and greasing. The motor, motor mounting plate, and solenoid brake are all out of the machine. ...

    My bad. :crazy: The "hoop" that gets formed from the 1" by 3/4" bar stock ends up looking like a very short piece of large diameter pipe: the pipe is 1" long, has a wall thickness of 3/4", and the...

    Thank you all very much for your ideas!

    Several people wanted to know more about the end-game. I want a scheme that makes the water clean enough to dispose of, and the oil sufficiently water-free...
  6. Remove a quart of oil from a 5-gallon pail of water

    Due mostly to poor planning on my part, I've got a 5-gallon pail containing about a quart of oil and roughly 4 gallons of water. I would really like to get the oil out of the water. The oil is very...

    Thank you all for your replies! It seems that I've dated myself somewhat. A little market research shows single-phase only VFD's up to 5 HP are indeed thick on the ground, and some manufacturers...
  8. Solutions to de-rating requirments for single-phase input to VFDs

    Generally, VFDs that allow single-phase input require de-rating the power controlled by the VFD to a value specified by the manufacturer which I've seen quoted between 50% to 66% of nameplate. In...
  9. Thank you both very much!

    Ray and Lionelt,

    Thank you both very much for your assistance on this!

    Lionelt, that old copy of Di-Acro sales literature was new to me. Good pictures of the spring winder, and a lot of other...
  10. Di-Acro Spring Winder - drawing for crank/cam assembly or source for same?

    I recently bought at auction a Di-Acro Spring Winder. It's missing the Crank/cam assembly that clamps onto your mandrel and lets you wind the spring. Di-Acro no longer produces the spring winder. ...

    I like Festool's drills. They're made in Germany, and are very well designed. The battery powers a tiny 3-phase VFD which drives the motor itself. The motor is a small brush-less 3-phase motor. ...

  15. Repairing a Reilang #3 Single-Pump Oiler

    I'm repairing an old Reilang #3 single-pump oiler that I bought at auction. For too much. Moisture got inside the oiler and corroded the spring and both check-valve ball bearings. It was pretty...

    I'm sorry to be dense, but even after I logged into Photobucket your photographs were marked "Private". Would you mind checking to see if you've got them protected somehow?

    Thanks!

    Your work is beautiful! I was wondering, on your "Ejector" model knife, what is the function of the small copper stud on the butt of the haft? It has the look of James Bond style functionality; but...

    Larry,

    Thank you very much for the excellent advice! I've found that, as you said, the Hardinge dividing heads are plentiful on the used market and the mounting plate is available too although...
  19. Mounting a horizontal 5C dividing head on HLV-H cross slide

    I need to buy and mount a small horizontal dividing head on an HLV-H carriage, preferably on the cross-slide. The head will be holding a 1" long piece of 1" diameter rod. It would be great if the...

    OK, nailed it! Thanks very much for the excellent advice! I looked around at several finger brakes, paying attention to the gooseneck punch tools as Metlmunchr recommended. I ended up making two...

    Tom and wippin' boy,

    Thanks very much for the good ideas!

    I bought a seamer and gave it a try; it worked pretty well on the tiny piece I'm bending. It is hard to get a clean sharp bend; I'm...

    Robert123,

    You are correct; mea culpa. I was thinking of wrought C300, another electrical copper. C360 is free machining brass, and useless for any sort of electrical work.

    Thanks,
