Too funny. The local steel folks here have the same sign. Years ago Welder Services was open Sat. No more.
And we have one metal supplier open Sat. And everything there is aluminum price too. And no matter how small it is $20. I get most of my stuff during the week from an iron works shop a friend owns.
So the 3" nylon worked fine, I will get a couple (only since I have to pay shipping). What happened to your hands. If in a shop, I can relate. But I normally bugger up one at a time.
