I had to do some plumbing today which involved replacing a leaking outside faucet and the shut off valve going to it in the basement. I learned long ago that that the new lead free solder requires more heat than my old propane torch can generate and being too frugal (cheap)to buy a new MAPP gas setup I've been using my old set of oxy acetylene torches to get the job done. I carried the tanks into the basement and as I was installing the gauges I wondered how many times I've hooked up these gauges and torch set over the years. I got the set for Christmas when I was in my early teens and became interested in playing around with cars which makes them well over 50 years old. They were made by Craftsmen in the days when that brand was hard to beat. In all of that time I've never had to do a thing to them ...They just keep going like when new. I've also got fairly new arc and mig welders but the good old torches still get a workout for general cutting ,brazing ,welding and bending. Do you guys have any tools or equipment that have been with you from day one and have stood the test of time?
