    Unfortunately I can't find a manual for this VFD, so I don't have any pot data given in ohms, just volts.

    So if I use a center taped pot, then go for a 4K, but if I go with a Balance pot, which...

    From my measurements, most of what they had was 18" and larger (mostly larger). Chucks were all over the place in size and mostly large cam-lock or L-series mount.

    So according to the tag on the VFD, those options are 0-5v, 0-10v, 4-20ma, and it does advise that there should be a jumper between two terminals for the 4-20ma connection. Nothing notes what to do...

    Just bumping this one up.

    I'm still on the lookout for a 8" to 15" 4 jaw.

    It looks like this mill could have been made between 1871 and 1899. I'm inclined to think it's on the early side given that most of...

    If someone had another Brainard to use for a pattern (and a lot of time), It probably could be brought back. Even without another Brainard it would present a fun project to DIY a mill. The saddle and...

    What brand/model scales are these? What kind of display are you trying to use?

    AFAIK, each manufacturer has their own way of building scales, so in general you can't plug any scale into any...

    Same here, lol. I'm researching how to convert what's written on the VFD into a "xxxx ohm" rating. I think I had gotten the 1000 ohm figure from a similar sized VFD, but now I want to be certain it's...

    Most lub guns that are meant to work with oil and zerk fittings will look the same as a grease gun. The difference is how they seal the reservoir that holds your lub. Some guys have modified grease...

    I've seen those spherical fittings on other 1960's and older German made machines. It's made to work with a concave cone shaped lube fitting. The gun would have a pump action neck so that as you...

    Ok, I think I've given some mixed info. My 1000ohm potentiometer figure was old notes and I'm not sure where i figured that from. I went back to the VFD connection drawing (sorry it's so blury) and...

    Forgot to add too:

    The machine will have a main power disconnect to turn everything on and off. For a safety, I was also going to add a foot pedal along the front of the lathe that would kill...

    That makes sense. The center tapped pots I'm seeing all have four terminals, so your wiper and V- wire straight to the VFD's terminals, while the VFD's V+ is toggled between V+ (fwd) and V+ (rev).

    Here's the VFD. I know it's old, but it does work, and if I can get the remote control right then replacing it in the future won't be a problem.

    The VFD is an new-old-stock older model Ace from Boston Gear (I posted awhile back trying to find documentation, to no avail). It does work, but I'd like to keep the design...

    I'm setting up my 1909 Hendey Engine lathe with a VFD, not for voltage or phase change, but for speed control. The lathe was a...

    Not having power feeds severely limits the machine's capabilities IMO. I think you are on the right track replacing them. You might also get lucky finding used parts from a machine being parted out....
