I Don't believe this!
I bought a Niles Lathe Back in Oct 25th 2017, after getting it home I went on line to find information on the Machine. Like you I couldn't find much of anything. I did find a add for one for sale and I saved the link. Mine is machine # 22127 It was originally a 34" swing lathe but someone Raised the Headstock it is now a 46" Swing X 192" between centers. I was told it was about 1965 but I cant find anything on Niles Lathes. So yesterday I found the link I saved and was looking at the pictures one was of the change gears. I wasn't sure how the gears went. I have the original gears but they used bigger gears because they raised the Headstock. I want to gear it so I can cut Metric Threads but haven't got the right gears to do it. I do another web search today and find this conversation on a Niles Lathe, so I join so I can see your attachments and pics. When I got on tonight I couldn't believe it. Here is the link I found back in 2017
Won't let me post link
When I saw your pic of the gearbox that needed fixing I realized it was the lathe on the trailer in the link
Small world, How have you made out with your lathe? Mine has a bunch of change gears to go on the front of the carriage, they must be for cutting a taper.
Have you found any information on Niles Lathes or sites
Thanks for any help you can provide
