About 6 months ago or so we ordered a custom-ground XTAL filter for a job..... They still make them, and they still take forever to grind and ship them! :)]]> http://www.dslreports.com/forum/remark,20290210 Sun, 06 Apr 2008 00:16:16 EDT Re: Crystal grinding: When electronics were REALLY hands-on http://www.dslreports.com/forum/remark,20286637 jacour : I used to live in Chicago and belonged to ham club that had an informal breakfast every Saturday. The club was filled with old farts in their 70's and 80's who had grown up during the depression and went on to work at Motorola and other electronics companies. A lot of them did time in WWII as telegraphers. I really miss the stories they told. Two that stand out:

One guy used to troll the alleys looking through garbage cans for parts like wire. He also claimed to have made crude tubes out of old medicine vials. Now that was hands on homebrew.

The other was a guy who was drafted during the war and assigned to a communications unit. There were two kinds of jobs in his unit; one was sending and copying code and the other was climbing telephone poles to play with wires. If you could not copy code at 13 WPM by the end of the eight week training program you were assigned to climbing poles. Apparently the life span of those up on the telephone poles was severely limited since they tended to attract sniper file; and he needed no further incentive to get up to speed.]]> http://www.dslreports.com/forum/remark,20286637 Sat, 05 Apr 2008 09:33:27 EDT Re: Crystal grinding: When electronics were REALLY hands-on http://www.dslreports.com/forum/remark,20285138 drjim : DUH! I haven't done that since my Novice days! Valve grinding or rubbing compound for a big change, toothpaste for a small one!
