I forgot to post before, here was a device to flatten and remove marks from the disc, without the need to remove it from place

replying JJ Wharrys, yes the support to hold the diamond was built with scrap parts, it is still being improved, thank you Stylus Maker, your information is very useful, my configuration is just a starting point that now needs to be improved according to the information and knowledge that I acquire

A brake disc driven by a belt was then used, I use a dc motor with rotation and direction control, the screws that hold the disc were cut and worked to have exactly the same weight and avoid vibration

Hi, I did this experiment using a car brake disc, it's not as flat as I imagined and it was necessary to make some corrections, but it worked, I made some points successfully, I still can't get a perfect sharpening without any noise but I believe that more dedication is needed, and I hardly have tim...

I recorded a song that has very open stereo, I didn't put the bass in mono and I had problems as you will notice in the audio, there were some jumps and landurfing. See in the video the angle of the shaving head and the stylus, if you can use a headphone you will be able to perceive the stereo with ...

hi, i get a good separation of l r channels, tell me how to post audio here, could you send me a song that you know well and i can audition

I never tried to do it the other way around (reverse rotation), I didn't think it could make any difference, I'll try to do it

I've been working at different angles, here I made a polished edge like in lacquer cutting styluses, and with a slight curvature that gives me a very good and clean audio https://i.ibb.co/dGCkkT5/PICT0003.jpg [/url] https://i.ibb.co/q5mpyyr/PICT0004.jpg https://i.ibb.co/gZBR4q6/PICT0008.jpg https://...

hi, i can move my cutting head to any angle i want, i have a little more stereo aperture with an inverted cutting needle where i get a lot more sharpness. I'm doing other stylus geometry types with interesting results

Also check that the connection of the coil to the torque tube is tight, if there is any soft spot in the middle of the way, your treble will not reach your stylus, all interconnected pieces need to work as if they were a single piece

I saw in a scully suspension box that had a speaker that was connected to the system and did this depth adjustment function, if you put a tension the coil comes out and pushes the cutter head mechanism down

I do the roughing in this simple way, today I improved the tool that holds the needle a little and gives the right angles ... for roughing I use grinding wheels made of printed circuit board, I use the copper side up with diamond polishing paste . This system works well for tungsten carbide and sapp...

I do it with plotter needles set at the right angles, they last a few hours and break the tip very easily

making a cone for a good cutterhead is not an easy task, after many attempts and finally you can make one and soon realize that you need 2. I created my way of making and making as many as needed, always everyone is the same size and a lot lightweight, but it was necessary to create a tool in the sh...

very good job !

made with beer can, I made a metal mold to get this shape

the screws are very tight, holding the V spring very firmly, only the spring can flex, the pen holder is fixed with a rigid wire on the rear support, the whole set is very rigid and also very light
