Growing Rochelle Salt crystals??
#4

Well Syl, I guess that's, that. but it sure would be a kick if someone could figure out how to grow/cut/acquire crystals. And boy do I love a challange. I did here from someone who knew someone that worked at C.T.S Knights and he said they would cut the soft crystals with a thread that was weighted on each end. Not much to go on but it's a start. When I worked at Fermilab we cut silicon with a diamond disk flooded with a coolant, a slow process. Of course you can't use a coolant with the Rochelle crystals so we tried it dry and even with the lightest pressure they would just crumble. Gotta think about that thread a bit. I'm would think that an electrical connection could be made with a dot of conductive epoxy, I don't know any other way one could do it in a home shop, that is if he could get a crystal properly cut.
And would those "1$ a pop mikes" be ceramic with maybe 1v or less output?

Is Gib one of the owners FStephen? I thought West tech was in the business of rebuilding cartridges, I would be very surprised if they were giving away their secrets. I've found that most of the guys that have developed methods for rebuilding old radio or phono parts are kind of secretive about it, that is except Syl, he's given freely of his work. Even with his instruction I'll bet 95% of the guys that try it end up failing. That looks like some very delicate work.
