These generally involve some other sorts of hardish plastic blanks. that's a different, much harder material. To be clear: None of these techniques involve cutting into the vinyl used in a pressing. I do not believe services that involve embossing (vs cutting) will work in this particular project. There are several users on the site offering these services. Even with cactus needles, the sound will be torn off the record, soon enough.Ģ) So, the other alts would be some sort of cut into a more durable plastic material, using a diamond stylus instead of a standard sapphire. So, while this particular playback in the video sounds great, these records would be unlistenable after roughly 6 plays-maybe a few more plays on a very well-maintained and well-designed UK Columbia or HMV machine, rubber gaskets all replaced, etc. that's how you get high frequency response. They are designed to give way when a sharp instrument cuts a groove into 'em. Problems with what I did: Acetates are VERY soft. You will also need a cactus needle sharpener to maintain the tips. A steel needle would have torn right through this, but Greythorne-brand (or RCA Brand) shaped cactus needles will play records made of most materials softer than shellac. **CRUCIAL: Playback was with milled CACTUS NEEDLES. (It was probably a Stellite standard-groove stylus. I was using a home-cutter from the 1940s, with some NOS 1940's stylus in it. The whole point of shellac is to resist being cut into.ġ) What I did: I cut into Apollo or Transco-brand acetate dubplates. I am unaware of any way to do a one-off cut directly into shellac. "Pressed" records are generally mass-produced, and involved a complex process of:Ī) cutting a master into a very soft material (acetate),ī) making an electroformed metal "negative" of the record, andĬ) installing this into a pressing machine where harder copies are stamped from this negative, from molten materials.Įven if you had presses that were set up to handle shellac (and that's a big if), it would be a complex process for just one record. Any labels issuing 78 rpm records are probably issuing them on vinyl, which will be torn up by a gramophone with a steel needle.ģ) Familiarize yourself with the difference between a "pressed" record and a "lathe-cut" record. I suspect they were impossibly noisy.) If it's modern vinyl, the steel will stop the record after gouging it.Ģ) I would love to be corrected, but based on the topic "Pressing Shellac Records?" I don't think anyone is currently _pressing_ shellac. (I suppose there were some home aluminium records. If you intent to play a record using a traditional steel needle and a traditional incredibly heavy reproducer arm, the material must be shellac, or something that hard. Shellac is MUCH harder than vinyl, and harder than the materials like makrolon polycarbonate that are used for some kinds of one-off "Lathe Cuts." It is also MUCH harder than acetate. Shellac (not vinyl) pressing is needed if disposable one-play steel needles are used.ġ) 78 records were traditionally made of shellac. ![]() Here are the problems which must be considered. I'll show a video of me doing it later in the thread. marc_parazon wants a record that will play on a non-electric, or "acoustic", hand-cranked machine that plays lateral-grooved 78 rpm records of the RCA Victor variety.įirst of all, it KINDA can be done. Let's be sure that we are clear about the desired result. Marc_parazon wrote:Therefore, i was wondering if you could help me on that : I wish to press a vinyl or shellac or whatever record of my own music that could be played on a gramophone.
