Steve,

Sorry to hear about your broken shaft.
Have you found the detail drawing amongst those already scanned and posted on here?
If you can't find it, let me know and I'll have a look through the originals.

Steve,

Are you sure that is the number for the shaft?
ML 115/930 can be found in this pdf - https://www.denfordata.com/downloads/for ... 0scans.pdf - which shows a fixed dog & gear.

Can you post up the relevant part of the assembly drawing that you have?
Edit - just found the assembly drawing ML 115/900/M on a different thread, and I think the shaft number is ML 115/923.
I'll see if I have it - may take a couple of days.
Second edit - found the drawing - will try to get it scanned tomorrow.

Drawing ML115/923 has had 10 modifications over the years.
Attched are the mod notes as far back as still exist - I don't know what happened to them for pre-1967

Steve - you don't say what year your lathe is, so i hope these cover far enough back to match the design of your broken shaft.
