The Secret Society of Lathe Trolls

I am a new member and enjoy this group. I started cutting acetates in 1950 on a home made lathe when I was 13 yrs old and didnt stop until 25 years later! As a professional disc cutter I have used a lot of different cutters and lathes, some good, some not so good Anyway, I noted the earlier post concerning the RCA 11850 c/h. I used that during the middle 50's into the mid 60's an my personal (home) machine. With mods,this unit can do a good job. I converted mine to feedback op and it always sounded good. Not as snappy as my Grampian or Cook but not too bad.
I have posted 10 pages from G Sterlings 1950 book "The Radio Manual"
which deal with the RCA 11850 cutter and lathe. This reads like a mini "how to" for disc recording. The file is a zip file around 14 meg so it is a big large but fun to read. The pages are in pdf format.

I may bore you all from time to time with exploits from many years of cutting laquer for fun and profit.
