Chirping sound on cut

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.

Hey guys (and gals) ..

I notice some chirping sounds on my cuts lately. Almost like a birding tweeting .. not loud, but noticeable. I am cutting with a Grampian and diamond stylus, no heat. Any ideas?

sounds like the stylus skipping every so slightly (unnoticeable when watching) could be due to warped blanks, or slight imperfections.
or just caught chip causing the stylus to raise up and dig in when it comes back down.
I've had this a few times, usually re-calibrating the weight on the dashpot/head weight on the VR helps.
For the lofi Presto setup - I've had this issue embossing when the stylus catches the blank the wrong way and makes some chip.
(could have been the blank, the stylus angle shifting over time, etc)
