I found the idea for the shovel pan here http://www.calsmith.org/techniques/projects/simpleshovel.html
The pan part is simple, strong and easy to make. The handle is 7/16" CRS and the basket twist is made with 6 pieces of 3/16" CRS forged onto 3/16" tenons on the 7/16" handle and a short 7/16" piece at the end which gets tapered and formed into a hook. The rivets are made from a piece of 6 AWG copper wire.
