These connectors are made here, as best as I can tell. There are several different brands. Grainger sells several of them. The solder ring shrinks around the wires when heated. Continued heating melts the ring into the wires. The rink shrinks down onto the wires. Then, more heat makes the ring melt completely and the insulation melts, too. Melting the ring halfway or 3/4 way into the wires, but leaving some of the ring intact around the wires seems to be working.
A guy was shot and killed in a city park within eyesight of my house early this week. Another fellow was gunned down on the sidewalk three blocks from my house a few days ago. I heard the shooting. There were a lot of rounds fired fast in uneven sequence, like more than one shooter. It seems these were innocent folks like me are the victims who were in the wrong place at the right time. A lot of the work I am doing is outside on my truck and trailer where I am an easy target. Its hard to concentrate on fabrication when one has to worry about some clowns walking up and murdering you. I wish I was at speedweek. lts crazy around here.
