More welding. This process is going to take awhile! Since this will stretch a week or three, I made up a tag with a rubber band with "NEXT"on it. When I'm done for the day, I hang the tag on the next cluster to be welded. I may leave the project for a few days and it will serve as a good reminder as to which cluster is next. I'm following a sequence and I don't want to lose my place!
