Wow. Unanimity. Amazing.

So two fins repaired easily. The third actually completed its split. And in the process of repairing that, it got a little papering anyway, with the CA bonding the fin to the index card underneath. I cut away the surplus card and sanded away as much as I could of the glued card.

I'm really happy with this model. The 3-D printed fin jig did its job. Just need to prime and paint and it'll be ready for a trip to the playa. (Pics after I get back.)
