Quote from: MaximRecoil on August 27, 2022, 04:23:31 PMDo you know what the part number is for your old RadioShack brand crimper?
Quote from: TelePlay on August 28, 2022, 08:35:50 PMI just looked at my crimper and there is not part number on it, anywhere, just Taiwan and the die sizes.
Quote from: TelePlay on August 28, 2022, 09:36:55 PMI see some on eBay have "Cutter" instead of Taiwan but I assume whoever ordered several gross imported of these asked to have that on them instead of Taiwan.
Quote from: HarrySmith on August 29, 2022, 03:08:09 PMIf done properly you would probably get a good connection but the hook shapes work fine. There is no question of the connection when you do it that way.

QuoteI don't think I have ever seen a crimp that did not fully encapsulate the wire,
QuoteSoldering is good but tricky and takes a lot more time (and won't work on tinsel).
QuoteAnd, wrapping one solid conductor around a screw terminal would work but putting 2 or 3 on one terminal would seem highly unstable, a dicey connection, with temperature changes and ringer vibration over time. Three spade lugs on one terminal is relatively easy to do.
Quote from: TelePlay on August 29, 2022, 07:20:38 PMAbout 4 years ago, I came up with a way to solder splice two tinsel conductors together.http://www.classicrotaryphones.com/forum/index.php?topic=20752.0
Quote from: TelePlay on August 29, 2022, 03:48:31 PMBending bare copper around a terminal screw is fine in a wall Jack or the like but I find it highly unprofessional to do that inside a telephone, be it a D1, 302, 500, AE 40, SC, stick base, subset or anything else.Not only does it look cheap, and is not the way the manufacturer did it, but the use of a spade lug over the wire insulation gives the connection more strength, especially with solid conductors which can snap off with too much flexing.And the spade lug is always a tighter connection.Only takes a couple of cents and a minute or two to do it bench professionally. Techs in the field probably didn't have the time to play with a crimper and lugs but no excuse for not using lugs on a workbench restoration.
