i am searching for a reasonable way to obtain 3 to 4" copper cut nails (square) of a size about 3/16" on an side. i would greatly appreciate any information on sources of nails for purchase, or for information on making nails from bar stock or other techniques. they are to be used as replacement fastenings in the restoration of a Swedish made vessel. also, what is the general opinion on using round nails as replacement rivets where the original rivets were square...?
thanks very much for any advice!
