has anyone here experience making the embossed aluminum records that were commonly used for airchecks before the introduction of lacquer coated discs?
O have several recording lathes, mostly Presto (a couple of 75A's and a K-10, along with an RCA unit) and was hoping to find a diamond-tipped "trailing point' recording stylus so that i could experiment with this format.
One advantage of this format is that the records may be successfully played on acoustic machines, if a fiber needle is used.
Anyone have any pointers?
