Providing A Good Mastered Audio File Yields A great Soundi

Lathe cut records are crafted from clear or black polycarbonate plastic and are cut individually each time, ensuring high audio quality. Using a record lathe, grooves are carved onto the discs. These lathes are used in the vinyl manufacturing process, particularly for cutting the lacquer master discs needed to create metal stamps for pressing.  

My lathe cuts are etched into clear or black polycarbonate discs, making them highly durable. 

I buy 7.5" x 7.5" square polycarbonate sheets in bulk, and trim them on our circular cutting machine. These discs are the standard record size of 1/16" thick and 6-7/8" in diameter, conforming to the RIAA industry standards.

To create these lathe cut records, I manufacture sapphire needles for embossing. This needle enables me to cut or emboss around 300 discs before showing signs of wear.  

Before cutting, cleaning off any residue from the protective "Peel-Off" plastic film is vital. I recommend using lighter fluid for this, as it effectively removes any invisible adhesive residue without softening or lubricating the polycarbonate, which evaporates rapidly. I avoid using products like "Turtle Wax or DW-40" and prefer to emboss in a dry environment at room temperature without heat lamps.  

Records made from polycarbonate offer significant longevity, comparable to CDs, although they are less brittle. Both materials are much more durable than acetate lacquer, allowing for multiple plays without noticeable loss in audio quality.  

In terms of turnaround time, a lathe cut record represents an instant vinyl solution. My turnaround for 10 copies is just 2 days, making lathe cutting the quickest method to produce records. Unlike custom vinyl pressings, which can take several weeks, lathe cutting skips the extensive plating and pressing process, saving crucial time.  

The length of the audio program dictates the production time for each physical copy. 

The cutter head’s stylus etches vibrations directly onto the disc surface, if a song is 4 minutes long, that will be the cutting time to make each disc. 

My lathe-cut records provide sound quality that rivals pressed vinyl. However, for longer tracks, like those over 5 minutes, the recording volume must be lower to maintain optimal audio quality. Each lathe cut will consistently sound the same from the first to the last copy by keeping all audio settings the same, ensuring quality in every disc.  

You can order lathe cut vinyl records without any minimum requirements. Back in 1970, vinyl pressing typically required minimum orders due to high costs. However, the economical nature of lathe cut records allows for orders of just one or twenty-five, catering to independent artists who want vinyl releases at competitive prices.  

Embossed records deliver sound quality comparable to pressed vinyl without hisses, clicks, or pops when embossed with a sapphire stylus. Despite receiving a bad reputation since the 1980s due to the use of tungsten carbide steel styli for embossing, I’ve refined the process by avoiding heat lamps and other lubricants.  

For optimal results, lighter fluid should only be applied for cleaning discs before the embossing process to eliminate residue left by the peel-off protective plastic film.

Using a louder recording volume can lead to random skips in lathe cuts and stereo embossed records; therefore, maintaining the average level of a microgroove LP recorded at 33 rpm is crucial for quality. Many have inquired about the sound quality difference between black polycarbonate and clear; the answer is that both provide the same excellent audio quality.  

Lastly, ensure that anti-skating is adjusted for the best playback results. If your playback stylus weight is 3 grams, the anti-skate adjustment should similarly be set to 3 grams.
