Where d'ya find carborundum powder?
"Smokey" wrote in message ... In the 1960s I ruined many a crystal following the guidelines found in ham publications then for raising the frequency of my FT-243s. Of course I used Comet or Ajax since that was all that was available. Now, lo these many years later I am ready to give it a go again only this time I'd like to try it with carborundum grinding powder. I have checked the local hardware stores and the response is typical for the Jasons and Jareds who have no business working in such a place. When they ask you to repeat "carborundum" its a sign they'll be of little help. I've tried automotive parts stores and, while carborundum is used in cylinder compound it is mixed with some other chemicals I am not sure would be good for my quartz. One idea was the guys that polish rocks and collect them. Hobby stores? So where do YOU find your carborundum? I'd like to know because I can't find it. Even the people at the glass etching place in town thought I was gargling when I said the word "carborundum." Thanks for your suggestions. de W9STB Technique is important, there were many articles that stressed the proper techniques to grind the crystals to keep the quartz plate surfaces perfectly parallel. A lot of hams would grind down the edges, which caused a loss of activity or a dead crystal. Pete |
