loved the wood fin production post…
just though i add a trick that i use for center fins that really helps keep the cloth from laying down too much when only doing 1 fin, (Bert solved the problem by lining his center fins up in a row). anyhow i take a scrap piece of 1/8 ply or doorskin and then trace the foiled wood fin. then cut out the pattern about 1" larger all the way around. next i set the wood fin and cut doorskin onto my waxed surface and fiddle around with tiny shims under the tip of the fin etc, then i add 3 layers of 6oz over the whole thing let it dry, flip it add the rope and another 3layers of 6oz…
the photos i have attached are of a set of keel fins that are ready to cut free…
i also added some photos of my on the fly fin grinding clamp…
