This video shows some of the stuff involved in creating a Spirit board.
Unfortunately, I did not end up filming a lot of the finishing. Whenever things go a bit wrong and I go into trouble-shooting mode, I always forget to start filming π (especially if there's a time constraint).
A lot of trial and error, re-epoxying rough spots with uv resin, sanding that again, more uv resin, sanding again.Gluing the three boards together.Routing the edges.Final sanding.Staining the back.Finishing with polycrylic sealer.More sanding, re-staining, re-finishing again.... but at least you get to see the end result. π
