Logan Model 200 Lathe
I currently have a tweaked Grizzly 9x20 variant that I am pretty happy with. Recently someone pointed out an old Logan model 200 Lathe in my area for sale. I thought it might be a nice "upgrade" from the Asian lathe, and a cool restoration project.
Looks like the typical old used lathe and I'll be going to look at it tomorrow. Looked like it had some electrical work done when the newer 3/4HP motor was installed. It comes with a set of change gears since it does NOT have a gearbox, but nothing else.
Anyone know if I can add a gearbox? I found one for an 11" Logan 950, would that work?
You can add gearboxes, but it moves the leadscrew outwards.... and you really want to have the "automatic" apron if you have the QCGB.

I'd get a later mode though, the 11", or a later 10". The headstock nose bearings for the 200 are quite special, and replacements in the past have been very sub-standard. I had to make several modifications in order to use a new bearing.
The 11" takes 5C collets and has a bigger bore, the 10" takes 3C or 3AT. They do share the bed dimensions though.
with this one being serial number 18005 (1943?) I guess it is considered early, right? What is the automatic apron? I've read up some and see that early aprons had a single lever for the feed screw, and later had two levers. Also that the half nuts were redesigned later. What would be the failure mode of this area on an early model 200? The info on the "special" bearings is helpful to have.
You'll love the Logan. Parts are still available - used ones on eBay and new ones from Logan http://www.lathe.com (The new ones are pricey, but its nice to be able to get them). I'm not sure about an 11" QC box on a 10" lathe, could be okay. I just don't know. They use the same bed but you'll have to drill and tap mounting holes. The box is held by three bolts and two dowel pins. You'll need an apron and cross slide if your lathe doesn't have power to them like the SB model "C" lathes (I converted one of those a few years ago.). I just don't know if all Logans have power there. I believe you'll need a lead screw from a QC model. On the SB I had to change the gearing also. Scott Logan can give you an authoritative answer. Join the Logan Lathe group on Yahoo Groups. I believe its Scott's. Anyway, he does respond to all questions and is very helpful. I've had several dealings with him and he's always been top notch. BTW, I have an 11" Logan.
yeah, it's early. Mine is in the 12,000s, from Feb 1942, sold to the Corps of Engineers during the "Pearl Harbor attack flap"..
the standard apron is open-backed, and has power crossfeed only, with turning feed via half-nuts (if you don't mind wearing out the leadscrew).
The "automatic" apron is enclosed, with oil bath, and has feather-key driven turning feeds as well as power crossfeed and regular half-nuts. It is thicker, the leadscrew is farther out, and the carriage is different to accommodate that, IIRC.
Failure mode? Aside from wear, due to swarf and lack of oil, I don't know that there IS one.
The Logan is a nice machine...... the 11" and above were available with hardened beds and modern taper-mount spindle noses. I like mine, but I'd not turn down a good heavy Sheldon or Rockwell, etc.
Next to the 9 x 20, it will probably feel like an Axelson or Pacemaker......... for a while......
Well...it is safely in my garage tonight. Now to start the restoration.
