Time to bag it...with fiberglass that is. I'm using 2oz cloth and Hysol CL30. I usually use West but I happen to be out and it's snowing pretty good right now. This step took about 30 minutes.
Here's a shot of my fake autoclave. I point my space heater into the open side of a box to bring the temp of the bag up above 100f. The sandbag is to keep it flat against the glass plate underneath. Hopefully this will give me a nice straight trailing edge.
It took about another two hours to shape, sand, fill, repeat ... until I like what I saw. It turns out I estimated the length added to the trailing edge wrong and this one turned about 1/4" short. I'll live with that. I also removed a little too much material on the top of the rudder and had to fill to make it fit. Anyway, here it is just prior to primer.
Great effort Ben, just what this site needs. Here in Nelson, New Zealand we have a rudder mould in two halves. We glass the two halves, place in a 4 mill stainless rod foam fill and sandwich together.
When cured, split the mould and there's a perfect rudder everytime. [:D]
