Manawyrm | Sarah@slyka oh niiice, congrats :3
... hmm.. I've inherited an old cabinet-style grammophone recently which now works again. Do you think it would be feasible to cut a 78rpm record with your setup?
@manawyrm well, I can definitely spin it at 78rpm, but I think the groove geometry on a 78rpm record is somewhat different, requiring a different cutting stylus. I'd have to look up the spec for it but it should work in theory.
@slyka probably pretty different, on the other hand, i don‘t think the grammophone is very linear to begin with 🤭
@manawyrm well frequency response is one thing, getting it to track in the first place is another. The grooves are probably quite a bit wider and deeper on a 78, so I'd probably have to increase cutting force by quite a bit
@slyka ah! that sounds like it‘s probably less of a fire and forget one-shot operation 🫣
@manawyrm I mean, I'd still totally be up for giving it a try sometimes!
