Brilliant! How are the needles secured to the holes in the copper?
Very snug fit and then soldered in place.
Just made a 4 needle one today. Everything was great until I discovered that the copper block shifted very slightly while drilling hole number 3. I guess I will try again at some point. Grr. Hehe. Good things take time I guess 🤣
