I was able to get a good supply of wire hangers from the uniform service truck driver that I got shop towels from. Still have a bunch of them. I do occasionally cut one up for some odd use, though.
At my last job, we had uniform service. 11 uniforms. 5 in your locker, 5 at the cleaners, and 1 on your back. There was always a pile of wire hangars in a barrel that the service never collected. So endless supply.
Getting down to my last few lately. I like to cut them into lengths, bend them in half, and use them for giant staples to hold down Christmas decorations in the yard.
I apprenticed with an electrician for a couple years there as well. Right before he retired, I had to opportunity to teach him how to gas weld with coat hangars. We had a big project that used a lot of 4x4 metal ducting that took a lot of custom length pieces. He was fretting about getting the correct sizes. I said "Let's just make our own." He asked "Can you do that?" Sure! So we took some measurements and several standard lengths of ducts, went over to the truck garage, cut the ends off, cut to length, and I welded an end back on.
Then I asked him if he wanted to give it a try. We spent a few hours on some practice pads and he had it down pretty quick!
I'd known this guy since I was a kid in Boy Scouts with his 3 sons. He'd given me so many lessons over the years, and then 15 years later I'm apprenticing with him and he's showing so much more. I was really happy that I could share a skill with him.
He lived well into his 90s and in the last few years of his life he was making his own 3d printers. RIP Ralph!
