I have a Centuri MX-774 that I built a few years ago. I did not trace the pattern before building the rocket 
I converted the JimZ tif to a pdf @ 100%, printed it off @ full size, and it compares pretty close to my as-built fin. I had rounded all the edges, and for some reason the sharp edges of the fin are rounded too, but tracing around the fin, using a straight edge to recreate the sharp corners, it is pretty darn close!
My fin thickness measures 0.1" which is close to 3/32".
Here is the pdf print it at full size |
