Another Mystery Lathe

[Rory Brown]

Does anyone recognize this lathe?  It has an 18" bed and the swing is 7".  The guy that I got if from seemed to think that it is English, but it came with a Southbend book.  I can not find any markings on the machine.  I do not believe that Southbend made a 7" lathe and when I search 7 x 18 in lathes.co.uk I strike out.  Anyone care to offer an opinion?

Thanks,

Rory

Very cool! Looks like a Drummond B type: http://www.lathes.co.uk/drummond/page5.html

Lathes.co.uk doesn't seem to have any good colour photos of this lathe, so you might want to see if Tony is interested in yours. Please keep us posted if you plan to fix this one up!

You nailed it Ian!  Thanks.  I found a couple of youtube videos of the lathe in action and discovered that this one even has a serial number on the way bed at the tail end.  https://www.youtube.com/watch?v=-GEVuK4eazw

I will definitely be cleaning it up and then I'll have to decide whether to keep it or not.  I really only need one lathe and now I have 4.

This lathe cleaned up nicely.  Thankfully there was not too much rust to deal with, mostly grime and swarf that was in every conceivable crevice.  I think I got all of it, but would not be surprised if a few stray chips still show up.  The lathe came with a lot of extras, including a complete set of change gears, 4 faceplates, two chucks  each with 2 sets of jaws, a bunch of centers, tooling and a quick change tool post and holders and more.  The one lone gear has several broken teeth.  One faceplate has the same serial number as the lathe (3516) and some of the components had B.57 in the castings.  Other than that there are no other markings indicating the maker.  Unlike some manufacturers Drummond did not seem to feel the need to paste their name everywhere. :)

The headstock and tailstock can be turned to turn tapers.  There is a tapered pin in both to establish them perpendicular to the ways.

I still need to connect the motor and jack shaft and of course power, but thought I would share a progress report.

Wow, looks great! I'm impressed you managed to do that in only 3 days!

It wouldn’t have happened this quickly without your help Ian. I was lucky to be able to refer back to Drummond on lathes.uk when it came time to put it back together. Without knowing what kind of lathe it was I would still be trying to figure out where all the little bits go.

There's a couple of oddities with the accessories that I can't quite understand.  First of all, here's a picture that I had intended to include with yesterday's post.  The change gear set is complete but the 38 tooth gear has 12 missing teeth.  If you look at it, it is almost as if it were intentional.  Also there is a small chuck with an M1 taper.  It has two sets of jaws.  It came with one modified set in the chuck that were clasping a small bearing.  It appears that it was being used like a live center for the tailstock.  The tailstock has numerous centers and drill chucks but not live center.  Anyway, here's some pictures.  If anyone has any ideas about the gear or the little chuck, I am interested.  Thanks

Oops, here's the chuck

[Rory Brown]

  I contacted the previous owner to see if I could get an answer.  He responded to say that he never did use the little scroll chuck so I guess that mystery will persist.  The broken teeth on the gear were like that when he got the lathe many years ago.

Is that chuck set on a bearing? If so, it's for the tailstock.

Regarding the gear with missing teeth, they look broken off, but I imagine if it were done deliberately, they would be milled or ground off. That's a nice collection of tooling that came with the lathe though.

I agree Ian.  It is still puzzling to imagine how 12 teeth and never 2 in a row were broken off. Maybe it was a kid playing with Dad's lathe.  The good news is that there is no other signs of abuse.
