He probably won't show up around here, but check out his work on his YT channel. Some of you may have seen the Nautilus' he casts. He works out of his shed somewhere in the NW. He vanished for 2years but showed up today. From the looks of this recent video, he won't be pouring this one on his own.
I'd imagine at least a grand in rubber and a couple hundred in fiberglass. Metal costs maybe 2 grand? Looks like it would weigh 300 to 500 pounds or so when done
