I am happy with how they turned out. I sent the production files to Stevens Monday, so you should be able to order a rudder if you need one. He doesnt have it posted yet, but if you call him he can cut them for you.
I built mine by clamping all the pcs together with the alignment pins in place (1/8 sq stock left over from stringers). Then CAd it together with thin CA. I used my random orbital sander with 150 grit to shape it. Took about 15 min or so. With the different layers you can see if you are removing material evenly. Once sanded I sprayed the rudder with 3M 77, covered with 3 oz glass, one PC folding it over the leading edge so there is no seam on the leading edge. I then added resin and vac bagged in my handy food saver. The next day I pulled off the breather and peel ply, sanded smooth and varnished.
The glass is probably not needed since the core is made out of ply. I used the glass to ensure it is not coming apart and only adds another 10 min or so to do. With the vac bagging it is very smooth and uniform with only a little sanding required to remove the texture of the peel ply. I did buy a yard of breather and peel ply, but waxed paper with holes in it and paper towels can be substituted."
