The Talking Machine Forum — For All Antique Phonographs & Recordings

When you order records from Borri Audio Laboratories, you get something like below. This is an order for 4 recordings. The blanks are new ones made by me, and recorded just the same as brown wax records in the 1890s, with an Edison floating weight style recorder, and they are acoustic recordings. I prefer making acoustically recorded records, to electrical. I have improved some technical aspects of dubbing, where the resultant cylinders are loud, clear and wide range. I However I use mostly glass diaphragms. Notice the North American selection is on a North American style blank with the channel rim. Yes I do like the new plastic moulded records, but I like the challenge of making something authentic too, down to the formula, a re-creation of Edison's brown wax formula. These blanks are double spiral, brown wax blanks, the spiral is in the mold, and the records are unscrewed. I have several videos of this on youtube of the process both of making the blanks and recording on them. Modern stearic acid does give the advantage of a harder, more durable blank, and the new process of making stearic acid results in very quiet blanks.

I always find your adventures in making cylinders quite interesting. I'm sure that it would be expensive and difficult, but have you looked into a way to make black wax cylinders?

goes into some detail of how Gold moulded records were made in 1904. Hear is the patents for Edison gold moulded records. There is another set for pressed moulded records too. About 1908 the process used a long machine that spun bell shaped moulds that had compound squirted into thema, a lathe formed the ends and interior ribs, and then chilled in a water cooled cage, after that they were put on warm mandrels for 2 hours and pressed off of them.

This is my new record label, I hope you all like it. I made the collage picture of record making equipment.
