[78-L] How vinyl is produced..from a sapphire supremacist group!

[david.diehl at hensteeth.com]

"Outlast" is the term used here. Sapphire stylii could be resharpened many times since they consisted of a very long shank which could be returned to the manufacturer for an inexpensive retool. A piece of synthetic diamond of similar dimensions would have been very costly both in its initial cost and to refurbish. I don't think that I have ever seen a reference to a diamond cutting stylus in the 78 era. Steel was only for voice applications and home use (noticeable deterioration after 30 MINUTES), alloys like "Stellite" tried to straddle the mid-range.

And... I see he got the terminology right about "acetate" vs "lacquer" but I have to ask the 78-L Board of Experts about the veracity of this statement:"Diamond is not agood material for a cutting stylus, but is excellent as a reproducingstylus. Home cutting styli were commonly made of a steel alloy becauseit was inexpensive to manufacture but most cutting styli forprofessional use are made of corundum, better known as sapphire whichwill outlast a diamond and produce superior recordings."Diamond not as hard as sapphire? Really?Holy mackerel, there, Sapphire!RodgerFor Best Results use Victor Needles..--- On Mon, 1/4/10, martha  wrote:From: martha Subject: Re: [78-L] How vinyl is produced..from a white supremacist group!To: "78-L Mail List" <78-l at klickitat.78online.com>Date: Monday, January 4, 2010, 6:52 PMThe reply near bottom of page ... all about the "100 foot tall shaft" off the recording room, for the falling weight. Apparently they had no way of knowing how fast the turntable was going (couldn't count, didn't have watches with second hands, and no governors, I guess) so needed gravity to determine the speed. Okay. (Actually, about 4 feet was all they needed for the weight to fall ... )----- Original Message ----- From: "David Lennick" To: "78-L Mail List" <78-l at klickitat.78online.com>Sent: Monday, January 04, 2010 6:11 PMSubject: Re: [78-L] How vinyl is produced..from a white supremacist group!> Worked fine that time..don't know why it wouldn't have before. > International> Jewish Conspiracy, probably (also it's National Hypnosis Day..mesmerized > anyone> yet?).>> dl>_______________________________________________78-L mailing list78-L at klickitat.78online.comhttp://klickitat.78online.com/mailman/listinfo/78-l _______________________________________________78-L mailing list78-L at klickitat.78online.comhttp://klickitat.78online.com/mailman/listinfo/78-l
