I did a similar thing years ago to make a connector for a probe for a B&K (Dutch) frequency selective volt meter. I got a socket and removed the metal mounting piece around it, poked in some appropriate sized copper wires as far as I could. Wrapped some tape around it to make a tubular shell as a mold.Then I trimmed them at a some length and put some lubricant inside as mold release. Then I poured in a tiny bit of thin oil being careful to keep it off of the wires so that the epoxie that pour in later does not stick to the socket but does stick to the wires. I then pour in pour epoxie into the mold and lastly plug a socket on to the ends of the wires sticking out to keep them aligned. Let it cure, remove tape and unpluged it from the sockets. 73 Bill wa4lav ________________________________________ From: Boatanchors [[email protected]] on behalf of Glen Zook via Boatanchors [[email protected]] Sent: Friday, August 19, 2016 10:27 AM To: Paul Kraemer; Bob Groh; boatanchor; [email protected] Subject: Re: [Boatanchors] Has anyone ever cut the glass top off a miniaturetube to re-use the base?
It is also possible to make a plug from a 9-pin or 7-pin molded type miniature tube socket. Put suitable gauge solid wire in each of the tube pin positions and then solder the wires in place. Trim the wires to the proper length. Of course, remove the sheet metal bracket that is used to hold the socket to the chassis. This makes for a suitable plug that doesn't look "half bad"! I have done this a number of times and the plugs work very well.

Bob I have done that to obtain 7 pin plug. My poor experience using the "all you gotta do" glass cutting tricks I went a different way---used the cut off wheel on a Dremel. For safety I put the tube and cutter in a heavy plastic bag and that way all the debris was safely bagged and minimized any risk to my eyes if something went wrong. The cut was nice and clean and the side of the disc ground it smooth. Soldering to the pins requires scraping them clean and bright and using a good flux like Rubyfluid. Filling the "plug" with epoxy after soldering wires get you there. Also, the real deal plugs do show up on ebay once in a while, 9s more common than 7s. Making circuit board plugs is also a possibility but you need to solder suitable pins to some pretty small pads and then not unsolder them when you connect to the back ends of the pins. It works but not a quantity producible solution by any means---unless you just sell the circuit board and loose pins and let the buyer deal with it. Too bad those Vector plugs of the 70's are history. _______________________________________________ Boatanchors mailing list [email protected] https://puck.nether.net/mailman/listinfo/boatanchors _______________________________________________ Boatanchors mailing list [email protected] https://puck.nether.net/mailman/listinfo/boatanchors
