Built brake on my work bench IAW "27 years of the RVator." It worked pretty well and puts a lot of force on the rudder. I placed a 1/8" steel rod that I got at ACE on the inside to confirm that I had a nice rounded edge.
I wish I had a planer to clean up the edges of the wood in the brake. I spent 20 minutes finding the two straightest edges of wood, but there is a slight bend. The rudder has a very very slight bow in the middle that I think is from the wood. When I get it all riveted together, I am going to put the piece in the brake the opposite direction and gently bend it again. It turned out pretty good though.
See the Brake built IAW "27 Years of the aviator. Look at the equipment log for better look.
