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...

In regards to the "grind-your-own" philosophy: I think many turn their nose up at it because it makes perfect sense to "buy what you can. make what you can't."

BUT

Grinding HSS cutters has...

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.

For reference,...

I've never worked with a center-tapped pot. I've wired pots for VFDs and DC speed controllers that had two speed setting via two pots, and a toggle to switch which was in use by either a single pole...

Thanks for the replies!

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...

They were every February at a PM members shop near Navasota, but I'm not sure if he or Richard King are planning another there. You might message Richard and see when/where his next Texas class will...

I could use some help from some of you electronics wizards on here.

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...

Yes, the original post and his pictures seem to have disappeared....

Thanks!

I've honestly approached this lathe the same way out of necessity. From the beginning I knew I wouldn't have time to fully restore it right away and I would need to balance restoring parts...

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....

Cast parallels like these are also used for large surface-plate work and inspecting large machinery when it is commissioned or being rebuilt.

Haven't updated this project in awhile. Covid has hit our business just like everyone, but fortunately we're still very busy. I've just had to be selective with what "fun" projects I spend time on....

The center shaft has several sections, one of which could be bound to another. From my experience, grime and dirt don't so much cause wear like an abrasive media, but they keep oil from getting where...

That's wear from lack of lubrication. Friction sticks the surfaces together and motion rips them apart, causing the snow-ball grooves you see.

I'd say 1/16" deep is still rebuild-able. I would...

It sounds like there might be a shaft seized in a bearing. If you still have the top cover off, when in neutral, does the very back shaft and gear assembly spin freely?

More info on the Whitcomb Blaisdell company:

I bought an original catalog on eBay for the Reed Prentice Co., which also advertised Becker mills, and Whitcomb Blaisdell machinery. It didn't have a...

:scratchchin:My wanting eyes are seeing something closer to a 2 1/8x8 thread (2 1/8" being the spindles full OD).

IF that is the case, I can use it, but will need shipping to Conroe TX (77301).

I'll definitely keep an eye out for one of those. I have a stock 235 in my daily driver 53' Chevy 210 and have never been disapointed in it's performance (however I also never race it;). I'm also...

I like hendeyman's suggestion to make a portable chip pan. IMO when these lathes were built, you have to consider the low RPM nature of the machine means that most of the chips and coolant were...

Not yet. I'm planing on setting it up with a tachometer and making a stiff non-spring-return lever for the carb so the throttle stays where I put it, but it probably will need a proper governor too...

Havn't had a lot of time to work on this one but a couple updates:

I honed the spindle taper and it cleaned up fairly well. There's one spot that looks like a boring bar went in too deep. I...
