I think it's ingenious as the jig itself is just common stuff from any hardware store. I would love to just buy a jig and the frame materials and also get the template sheets. I wonder if the head tube is already pre faced and reamed also? The coolest thing is his change from hemp or carbon for the joint and just using cast wrap instead. No messy resin/hardners to mess with. After watching the whole set of steps he has on YouTube it almost makes me want to try out cast wrap instead. You can pick up a 10 pack for $50-60 which would easily do a single frame if not two.
