Share Quick-change Tools On Two Logan Lathes? Plus Tooling Recommendations

And here's the 10", with a surprise announcement to follow...



Needs a new belt. This one slips terribly. I've already found the specs from Logan Actuator.




My father disassembled the lathe years ago to restore it, including painting it, but never finished. First a move and then later a divorce threw off those plans.


Fortunately he has what we think are all of the parts.

The shiny chuck is a Shars special I picked up about 6 months ago. The old chuck was in rough shape, and we could never get it tightened enough to take any but the slightest cuts.


Of the tooling he has this excites me the most. It's a 10-pack of cobalt tool steel blanks that I can grind as I see fit. (Again, I have a T&C/universal grinder, but no tooling or fixtures for anything but surface grinding, and no real knowledge of how to use it yet anyway.)

Has a 6" 4-jaw chuck installed, and there's a 5" 3-jaw chuck in the box of tooling that I hadn't seen before. Must have been buried previously.

I had forgotten about the tool post that is shown here. Very frustrating to use, possibly more so than the lantern-type in the box. I'll definitely be getting an AXA for it.

And, the surprise announcement: it's going to be mine-ish.

This one belongs to Brother #2. Brother #1, who owns the garage where both are parked, suggested yesterday while the 3 of us were working on my mother's kitchen remodel, that we should pick a day to load up Brother #2's lathe to take it out to his newly completed Shopstrocity. (45'x45', wired for every high and low voltage anything he could need, plumbed with radiant heating, a full size mechanics wash basin, a full bathroom, a bonus room (I guess for when he's in the doghouse, but what a doghouse!), Rotary 2-post vehicle lift, etc, etc.) Brother #1 has a great garage but it's full of too much stuff right now, so the extra lathe has to go.

Anyway, Brother #2 said that he almost never uses the lathe (and doesn't really know how anyway), so it would make more sense at my house if I have room for it.

Yeah! I need to make room, but I have about 15' of wall space that is being used very poorly. I can fix that up with a couple Saturdays of work and then I can have my own (brother's) lathe in my garage! Sweet!

I guess I'll be making the tooling a higher priority than I had previously thought. :-D

Both lathes appear to be in very nice shape for their age. Just need a good cleaning and some oil slapped on the ways and slides and your ready to go!

Yeah, I'm from a family of three brothers. I'm the oldest, so when we sold the family homestead, I took my own lathe, the 13" and dad's 9" SBL. Middle brother sold off most of the stuff and bought him a decent 14" lathe and mill. Brother #3 got left with nothing! He did get dad's Gerstner 052 tool chest with middle chest. A couple years ago, I picked up another 9" SBL same as dad's but in almost new condition. He's happy right now. But I'm a little jealous of him right now. His new job he has now, he gets to play with all of the latest new CNC machines that get sold by his company.

That's funny. My "Brother #1" is in charge of IT for a manufacturer who has a row of high-end CNCs, including Wire EDM. He could have the guys at work run anything for him. But he still wants to learn to use the lathe, and I certainly respect that.

Actually I'm hoping that if it turns out I'm missing any parts for the Model 850 that he may be able to get them to just cut it out for me (assuming we can easily determine what the part would be, like a specific gear).

I also found out they have some laser metallurgical analysis tool. I guess they got tired of sending stuff off for analysis and bought their own. He says that one should be no problem if I need them to analyze something for me. So that whole question of "Is ____ made of decent steel so I can use it to make ____?" is actually a viable one for me. I have some 40+ year old saw blades that I've wondered about, for instance.

Don't you just love the QC on the model stamp? It really betrays the quality of these machines.

Yeah, that looks like my hand stamping!

The Logan 850 would originally have had a turret tailstock and no compound. In it's current configuration with a regular tailstock and a compund it is definitely more useful for typical home shop work. You might want to see if any of the old turret lathe parts are still kicking around. As it sits it is probably more or less equivalent to a Model 200

Here is a link to the sales sheet for the 850 from the Vintage Machinery Site:

And the manual for the Model 200 from the Downloads section on this site:

Nice get!

Well, it only took, what? six weeks? But it arrived today. The plan was for me to go help my brother load it up in the late afternoon. Instead he showed up early afternoon ready to unload it. I did not complain. Not even when he said he forgot the boxes of gears and tooling. I can handle going to pick those up.

He broke the "pin" that secured the flat pulley belt (looks like a staple to me), but I can fix that. And I already put a couple jam nuts and low strength Loctite on the pulley cover stay. I can't believe that hadn't been done before now. They're just #10-32.

The flat belt was already stretched a bit, and we suspected that was the cause of at least some of the chatter it was exhibiting the last time I used it. I just checked my assortment of used timing belts and I have one just barely smaller than this flat belt. Same width, slightly smaller diameter (the flat belt fits around the timing belt and barely doesn't close). Other than the issue of it being more complicated to install a continuous belt, do you see any reason to not use it? (Inside-out, so the teeth are on the outside.) I mean if it fails it fails, just like an oldschool flat belt, right?

The motor drive belt looks great. Time to figure out how to work a proper quick change tool post into the budget.
