Graham,
Don't leave us hanging. Show us some more pictures of that massive lathe. That lead screw looks to be about 1 TPI.

So this would be a gap bed lathe, correct?

That's right. Some have an insert that can be used with a smaller chuck and allow the carriage to get closer to the head. My lathe doesn't have an insert but the saddle is large enough that I can get the carriage up to the chuck.

Hi there, I have the exact same lathe which I am presently reconditioning. Rare as hen's teeth!
The brass information plate on my lathe's change gearbox is so worn that I cannot read the settings. Is there a possibility that you could send me a close up photo of the brass information plate on your Mitchell ?
Also - the cover on the drive/driven external change gears of my lathe is missing - can you send a photo of the left end of the lathe so that I can make up something similar.
Also - do you have a manual or any other documentation ?
Would be very grateful,
Regards, PeterT

Hi Peter,
I'm sorry but I sold the lathe earlier this yr as I didn't need such a large lathe, as my colchester does all I need, It's in storage at presently I'm told, I actually sold it back to a mate who I originally bought it off if I can get to see it I'll take some photo's, there was a picture of one recently in the model engineer.
Kind Regards Graham.
