This is where record cutters raise questions about cutting, and trade wisdom and experiment results. We love Scully, Neumann, Presto, & Rek-O-Kut lathes and Wilcox-Gay Recordios (among others). We are excited by the various modern pro and semi-pro systems, too, in production and development. We use strange, extinct disc-based dictation machines. And other stuff, too.
You should be real happy with this choice. I had an 8C and it was my second most favorite of many presto lathes I have had. I made modifications of mine for 45 plus the 78 and 33 speeds, vacuum table hold down, swarf (thread) removal, and hot stylus.
Nice.. yeah I have a 45rpm adapter and having a new screw made for micro groove since we could not figure out the complicated pulley system. I have a vacuum plate but no clue how to connect it etc. I will probably PM you. thanks!
