I thought copper was too soft for legs, so I didn't try using copper.
Let us know if they bend or lose the alignment with use? Don't they oxidize with time?
I'm using these pins for legs, I saw @Ivan TT recommending them and bought some:

They work very well and I also recommend them.
To be perfect they should be round (needle type) pins, but their face is square type, not a problem because the pins are very small, so the square is almost a round surface. I couldn't find round pins with this diameter and length.
me too using same pins and indeed they are great for the purpose..
