Recordette still not working? What gives? Improper weight?

This is where record cutters raise questions about cutting, and trade wisdom and experiment results. We love Scully, Neumann, Presto, & Rek-O-Kut lathes and Wilcox-Gay Recordios (among others). We are excited by the various modern pro and semi-pro systems, too, in production and development. We use strange, extinct disc-based dictation machines. And other stuff, too.

the styli transco supply have a heating coil already mounted on them but I dont know what one your head uses. you could ask gib at westtech may be a 362 transco might fit its a short shank grampian type you would use a 6v power supply at about 450mA current for the heating coi. Or you could try heating the disc with a lamp before and while you cut. Have you got the cut angle correct as this can cause surface noise? 15 degrees for plastic or 0 degrees for masters. hope this helps :?

I've had reasonably good success with a Recordette (78 RPM) with a cutter head I rebuilt myself, and steel needles that I grind from regular 78 RPM phono needles. I am using plastic picnic plates with the rim cut off, leaving about an 8" disc for recording. One MUST use the matte under-side of the plate, not the glossy "food" side. These are soft enough for a crystal cutter yet hard enough for playback on a normal phono pickup.
The cutting needle but be VERY sharp, and you can tell if it's working by observing the swirl of "swarf" that should exit from the cutting needle and spins in toward the turntable spindle. If there is no swarf and just chips & dust, it's not cutting correctly, in my experience. Excess noise is always, I would suggest, an artifact of a less-than-sharp needle and a disc material that chips along the groove bottom rather than cutting smoothly. You can see this under magnification. Hope this helps a bit.

standard scissors and a steady hand.
if you want to pick up a circle cutter, or 'compass cutter' that might work too.
making lathe cuts on a Presto 6N, HIFI stereo cuts on vinylrecorder
