Making Rochelle Crystals
Saw this just now. Wonder if it's possible to rebuild a crystal cartridge with this??
http://blog.makezine.com/archive/201...rew-piezo.html I've got a dud TC8-S cartridge, maybe I'll give it a shot. -VintagePC |

Interesting and worth a try. I would be interested in what the crystals taste like.

Well I have two or three 'dead' crystal cartridges, including one that is in a cutting head. I wonder...

Bob, lemme dig through my stuff. I seem to recall seeing that cartridge in my stash of stuff. I've got stuff from several repair shops and one distributor. Does your original cartridge look like the one on eBay, item # 250760246787 (no affiliation, used as a reference only)
Cheers,

Seems to me if you can get a nice clean crystal, and make good electrical contact to it, there's no reason it shouldn't work.
It will probably involve a 2-stage step, the second to re-grow a single crystal. This page describes how to use baking soda as an alternative to the dye fixer: http://www.seawhy.com/xlroch.html followed by a recrystallization for purity: http://www.seawhy.com/xlone.html One of the pages says they have a saline, cooling taste. Wouldn't eat too many though, Wikipedia says that the salt is used as a laxative :P You'd be better off trying it with sugar if you want something to eat... hehe. |

Nope these cartridges are much older. They have metal cases painted brown. One is large, the cutting head. The other is about half the size. If you have something close, I'll get the part numbers and post them.

just have to figure out how to form it, shape it, and make secure electronic contact with it. He shows how to make it, but it just forms in its own way.
my guess, is sanding? |

I think they use a saw to slice the crystal into small sheets, then fasten a contact to each side. Of course, you have to consider lattice orientation. One way to fasten the wires is to make a little (non conducting) clamp to squeeze the contacts against the crystal.

Dumb idea, before it does much crystalization drop a frozen or chilled mold with one or two openings in to speed the cooling/xtalization process and get the shape.
