The Talking Machine Forum — For All Antique Phonographs & Recordings

Chuck, I have pondered making silicon gaskets in a similar fashion to what you described. However, if you clamped a flat plate on top of the grooved plate, it seems the silicon would be trapped within an air-tight enclosure, preventing the solvents in the silicon from evaporating. I would scrape the excess from the grooved plate and then leave it open for the silicone to cure.

I take it that "glue" is hyde glue crystals? Glycerin, and Sugar. I think It might work well!

Yes, I believe it would be hyde glue. But many recipes include molasses, as the sweet element.

Having Letterpress printing as a hobby, and having used "composition" printing rollers for the ink transfer from ink plate to type, I can say that tradidional "composition" rollers are by far, much softer than any available modern rubber or synthetic based ink roller. They are much like a rather rugged jello, if you can picture this.

I am so glad that this ended before Uncle Josh described his experiences with anal probing.

Is that a heat lamp or just a regular light bulb you use? Do you keep the machine running while you let it warm up? That way the whole cylinder is equally warmed, right?

It is a heat lamp, I warm the cylinder on the phonograph, the cylinder is put on loose until it is time to record, then it is seated on the mandrel, the light is also backed off about 3" so the cylinder no longer expands, I usually have a digital thermometer and keep the cylinder between 85-105 degrees, 100 is about the best recording temperature. The temperature is very important to a good record.

That was great!, and quite amusing!
That 56" brass horn is something to behold!
