The Secret Society of Lathe Trolls

If its someone in Minneapolis, you should contact Dave at Hymie's records in south Minneapolis. He's a standup guy and sometimes purchases collections.

Supposedly souri has been developing a laser-based record cutter for the last few years. Supposedly it cuts faster than real-time. Has anyone seen one these machines? He told me he has a few prototypes out to a couple users.

What I mean is, does the 2b fit in a presto? Looks like the 320 is the Neumann stylus

Thanks, I'll check that out. Is westrex 2b the same as the Neumann 20:1?

Does anyone have a Neumann-to-Presto shank adapter for sale? I'd really like to get my hands on one.

It's a homebrew... Literally just a 1/2-10 acme leadscrew

Thanks for your help guys!

I've been trying to figure a formula for this, and I keep confusing myself. Maybe someone here can help. I'm trying to figure out what RPM range I'll need for the motor to control my overhead. Given a turntable speed (33 or 45), a desired LPI for the grooves on the record (say 200, or any value) and...

Hi trolls, I'm writing because I'm looking for a microscope. I'd like to find something that would be good for measuring grooves. I've tried a couple USB microscopes but they didn't have enough magnification. Anyone have a lead on a good microscope (USB or standard) that can be used for measuring gr...

Has anyone noticed a difference between cast and extruded clear acrylic? I've always used extruded, but a plastics guy told me cast would be better for the application.. So I ordered a couple small chunks that I'm going to try out.

Mark that's a great idea... I think I may try that

Lots of good information .. Thanks! I'll let you know how it works.

The sapphire could be completely broken off... I only care about the shank.

Thanks!

I wonder if you had a sapphire without burnishing facets if it would cut acrylic (or other materials) better....

I'm trying to do a very rough calibration of a meter to show the level of my cuts... Is there a couple examples of popular albums/songs that are 0dB cuts?

I'm just trying to get in the ballpark of 0dB.

Does anyone have a junk Neumann stylus that they want to get rid of? I'm working on a DIY cutterhead, and I want to try and get the stylus holder right before I try and stuff a new stylus in it, since it's a conical hole. Even if you just have the shank I'd be interested.

Hey trolls! So I've been doing tons of experiments with ruby + acrylic cuts, and have been getting pretty decent results with my 1C, especially cutting slower than playback. The one thing I'm struggling with is cutting a quiet groove. I've tried plastic polish, using lamps, heated stylus... Does any...

Not to hijack, but I ran across Palomino that can do 100 for $465... Has anyone ever used these guys?

Flo - I sent a private message and an email; I'm interested as well.

Has anyone seen this? http://www.youtube.com/watch?v=F5Z-b4vsjEw&list=UUtyC1tpIguhoDYnY67g7Q_A&index=2&feature=plcp I chatted with this guy a few months ago, it was hard because he speaks very minimal English. Amazing work though! I believe he is embossing using a homemade needle if I remember corre...

I've had good luck with springs from McMaster. Do a search for "precision extension springs" on their website. They have tons of options... I don't remember what I used, but that's where I got a replacement from.

What a great business model.
