Hi Ron .
Welcome to the MEW forum or the Brains trust as i call it and no the brain part isn't from me !
Whilst i can't name anyone specifically as i live in another country i would try to find a local model engineering club and approach them even if you're not into making models there should be someone willing to help and if anyone knows how to use an ML7 it will be a model engineer !.
Also there is the workshop practice series of books available – # 34 lathework a complete course by Harold Hall # 45 basic lathe work by Stan Bray are both excellent guides for beginners with the added bonus of making some usefull tools for your machine in the process .
There is also a series running in MEW that has dealt with basic lathework and metalwork so check out some of the recent issues .
There are also some DVD available from little machine shop in the USA but they will cost you some $$$ although they are are usefull but not specifically based around the ML7 .
It may take a while for other forum readers to respond as many only check them here and there so be patient !
IAN
