Josh Van Noy of Vans School of Blacksmithing drilling out the alignment pin holes for the cast molding flasks I made for a new sand casting class I'll be teaching. Making enough sides for 7 flasks was a lot of work!
Many thanks to Olfoundryman for making the free 3d pattern files for these flasks public! Check out the series on his channel covering how to mold, cast, and assemble them.
