ASTATIC X-26

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.

The X-26 isn't heavy enough to cut plastic. You need at least a low end magnetic cutter that has enough weight to cut into the plastic. You might get away with X-ray film or plastic dinner plates, but not the polycarbonate discs a lot of people are offering. Even if you added weight, I'm not sure what kind of frequency response you would get cutting plastic with a crystal cutter. Plastic discs are notorious for poor mid-high/high response because of their resistance to cutting (they're much harder than lacquer) - I have samples of 'club' music I received from an equipment manufacturer in Europe that sound very good, but lack the high end that a lacquer or a pressing would have. I've also cut poly myself and between poly or a lacquer, I'd take the lacquer any day for quality purposes.
