UPDATE, 13 June 2014: As I have an increasing number of other commitments now, I'm calling a temporary, if quite long, halt to any more developments. Thanks to everyone who's corresponded, commented or given advice over the last three years.

========================================­=====================
My home-made analogue disc recorder. This cuts sound records into sheets of plastic (actually polycarbonate acetate - greenhouse window material!) and old CDs. The records are "instantaneous" - that is, playable immediately, without any further processing.

This is the Mark 2 model, with the lathe driven by an 12v electric motor. The cutter head is my third attempt; although a considerable improvement on my earlier efforts, it still struggles to record the highest frequencies - hence the slow recording speed of 26 r.p.m. for 45 r.p.m. playback.

The recording turntable is a Lenco with continuously variable speed.
