![]() The turntable is a Reloop RP-4000 MK3, older record players are often too weak (except the Technics 1210) to keep a constant speed even with the cutting needle lying on it. The CD gets put on this round cnc routed platter and taped down on the sides. The price (especially with old advertisement CD's) is a good reason and some good results were achieved. The feedrate lays somewhere between 3 and 10 mm/min, depending on cutting depth, volume and speed.Īs cutting material (at least for the first tries) CD's / DVD's are not a bad choice. The threaded rod gets rotated by a small stepper motor with gearbox (also probably out of an old scanner or printer). The advancing of the cutterhead is done by a wooden block and a M8 threaded rod which pushes the whole thing along. A small groove in the wood enables it to ride along a steel rod (probably salvaged out of an old scanner or printer). Now the cutterhead only needs to be moved from the outside to the inside as precise as possible.įor this I screwed the cutterhead to a long piece of wood and attached a counterweight to the other end. I used a thread because the moving mass which needs to be accelerated by the speakers should be as low as possible. It was necessary to keep the needle from bending in the forward direction and also not to stress the speakers too much. Later I replaces the wall plug by a thread. Therefore I formed a cone out of some plastic sheet I found in the trashbin and glued a short piece of wire to its tip.īoth wires lead to a bare terminal strip piece in which a needle can be put in. The loudspeaker are going to move a needle. These were assembled at 90° in some sort of wooden box.īy the 45° angle of each speaker it is theoretically possible to cut in stereo. The Secret Society of Lathe Trolls, in my case especially the "Experimenters' Forum"Īfter I understood the theory good enough I started to collect parts for a prototype.įrom an old pair of PC speakers I salvaged two 5W full range speaker (diameter ca.The following links helped me quite well in the beginning: How a vinyl records works is something I'm not going to explain here. My goal is not to produce high quality records but rather to experiment and understand the rather old technic that goes into making these. Besides commercial solutions like Vinylrecorder or Vinylium for home usage it is possible to make the so called dubplates with some hand crafting. With this view of things I'm not alone, thats why vinyl is by far not dead and still produced.Ī great thing would be to be able to cut your own records. ![]() Vinyl records have (in my opinion) a more detailed, warmer sound and playing them is a different feeling than "cold" digital music.
