The Secret Society of Lathe Trolls

I have a Grampian type D, recently serviced.
could it be resonance at a certain frequency? it sounds like it happens at around 8k.

here are photos of head mounted reversed if anyone's curious. Its a grampian cutterhead on a Presto 8DG.

I'm not sure what you mean. I didn't say anything about creating a new facet. You just turn the stylus around for tommi's method. Peter grinds the whole tip of the gramophone needle into a pointed cOne. oh sorry, I meant your idea of using a vice to create a flat area on the opposite side of the sh...

heres a photo <a href="http://s1180.beta.photobucket.com/user/craftsingles/media/jaggedgroves.jpg.html" target="_blank"><img src="http://i1180.photobucket.com/albums/x410/craftsingles/jaggedgroves.jpg" border="0" alt=" photo jaggedgroves.jpg"/></a> http://i1180.photobucket.com/albums/x410/craftsingl...

Is this possibly what the use of Turtle Wax is meant to combat?

the ragged edge is very obvious, don't need a lot of magnification to see it. It is even causing enough drag on the playback stylus to slow the record! I'm not heating the Lexan, could this be a cause of jagged edges? anyone else experiencing this problem or know how to resolve it? The audio is ther...

anyone experience jagged edges in their groves using this leaning back technique?
I am using a backwards capps stylus on Lexan, and the edges of the groves become a zigzag basically as soon as any significant signal is being cut ... ?

ps. Also had head overhauled (incl. new coil) by Len Horowitz since last use.

Just resumed work on my lathe (presto 8DG, Gotham amp, Hrampian typeD cutterhead) after a year off ... having trouble remembering how to wire the cutterhead to the amp. gotham amp has 7 options at the input, Im using: 5 : hot 7 : ground and 7 at the output, Im using: 1 : FB hot 2 : FB shield 4 : (to...

thanks all ..
piaptk : the idea of creating a new facet on the opposite side sounds incredibly unlikely, since the angle would have to be so so so precise ... does anyone have any other solutions to this?

I thought it would be a good idea to start a thread about embossing. There are bits and pieces all over the forum, but it seems like a very promising technique for cutting pvc. Sounds like it reduces stylus wear and noise floor, which is great for those using their lathes a lot to produce multiples....

who repairs Gramian heads? anyone know?

I see. I have been unable to locate this service ... who in the world will do that for you?

Anyone have used long-shank diamond styli that they would like to sell rather then throw out? I am having best luck with a slightly rounded tip ... something that many master cutters would dispose of.

The material I am cutting prefers a worn Stilus.

I'd love to buy your used Styli! PM me!
