I’ll check the size when I get back home. I would not be an economical source.
I’ll pickup drops of different kinds at the scrap yard. Steel, $0.3, stainless, $1.50 per pound. Stainless bolts, nuts and parts are nice to weld up for tools or parts to steel easily and strong with mig. Big plus with stainless is no paint. Have bought specific stock from eBay and specialty metal suppliers.
I’m too old, slow and particular to make money fabrication for others. Do enjoy making stuff and trying out ideas. Do enjoy seeing what very talented people can create on this site. Innovated solutions to many problems.
