Is this a lathe or an albatross?
I was wondering if anyone here could help me identify this lathe. It only cost me the trailer rental (which may have been a warning sign) and is completely devoid of any labels or data plates. Even the threading gearbox plate has been wiped clean.
Basically I'm wondering if a lathe of this make is worth repairing or even repairable if it is missing all the back gearing. The spindle seems fine and runs on tapered roller bearings and the motor that was included will spin it up. I was told it was used an expensive polisher and destroyed by bored numbskulls crashing it. The carriage gears are all intact, the threading tumblers are also undamaged and the steady and follow rests seem to be new except for being stored under rubish that chipped their bondo off. Any help would be greatly apreciated (especally if I can tell my wife that some "experts" have declared it a boat anchor that must be replaced with a brand new one
Thats a great looking machine. You will have to go over it with calipers and rule to determine size and then try it with a clock to get runout etc.
Its a good size and if you have nothing else to do a bit of anti rust and some paint would preserve what is there for whoever eventually does the rebuild.
If you have work to be done, trade it in and get a new machine. One this size would cost a mint unless you go Taiwan or China.
Yhanks for the pics.
It can probbably be restored, but it's definitally a project, and you will need a friend with a working machine shop to do it. You will need to scrape the ways, saddle, and cross slide, probbably replace the leadscrew with a new length of precision acme rod and make some new half-nuts, get a new live & dead center, drill chuck, and QC tool post, and probbably a new chuck, in addition to making a new geartrain for the threading drive.
The other way to approach it is to do a CNC conversion - get rid of the gearbox and apron, mount a ballscrew and servo motor under the ways driving a ball nut mounted in the middle of the saddle, make a new cross-slide leadscrew mounting block with a motor mount on it, put a ballscrew in the cross-slide, and do the other things mentioned above. Oh, and don't forget a good coat of paint, with racing stripes - that's the most important part!
Basically, either way you go, it's a Gingery-style project, that you don't have to do any castings for - not a project for someone looking for quick results.
At first look I would say it is either a Sheldon or Logan. Me being me, once identifying the brand, I would take measurements to determine the wear on the bed and spindle. If those are not way-out-of-spec I'd make an effort to rebuild it. It's a crime the way some people mistreat machines.
i would restore it as long as the ways line up with the bore and are not worn it looks like a logan. a good heavy lathe
It is not a Sheldon, it does bear a resemblance, but none that I know of have a change gear box of that design, or a rear mounted drive.
It may be a Logan, but most of those I am familiar with have the heavy belt cover that also serves as a clutch.
Any lathe is better than no lathe, and if the bed and carriage are in reasonable condition, it could be made workable. Without a backgear, threading becomes difficult, but most other functions will still be possible. Fitting a VFD could solve some low speed problems.
If it can be identified, parting it out on eBay for seed money for a more complete machine is another possibility.
It is definitely worth the cost of a trailer ride home.
It looks like it could be a Logan to me. If there are any numbers on the castings these could be used to identify it or at least rule out a manufacturer.
If you decide not to restore, at least clean & paint the steady & the follower rests so they can be sold. You'll still need to identify the brand & size (the only easy thing).
For South Bend 9" & 10", the steadys sell for $200 - $400, followers bring $150 - $250. These are recent (last week) prices. Craftsman, Altas, Logan & Sheldon parts are almost as high.
If it were mine, I would use it as a dedicated flame-spray lathe. Metalizing lathes need only a slowly turning chuck & a tailstock that will support (mostly) shafting. Even in its present condition it is nearly ready for that.
If it is a Logan, the serial number is usually found on the flat part of the ways at the tailstock end.
Scott Logan sez it ain't a Logan.
