Tuny, Gregg, sorry I did not reply to your questions....just been in a rush all the time when posting I guess.

Tuny,
The laser tool is something I bought from Home Depot years ago that is a rather cheap laser with a magnetic base. I set it up on a steel block at the end of the work table looking a bit downward toward the front of the fuse. The laser lens can be rotated 90 degrees to show a horizontal line as well. Works great as a sight line tool for measuring and former alignment. I should probably replace it with something newer...just in case I need to hang a picture or something... http://www.homedepot.com/webapp/wcs/...ctId=100375599


Gregg,
I think I misunderstood your question about the rudder. I first thought it was in reference to my poor picture taking.....if so, I reposted a more complete photo of the fin and rudder. If it is in reference to the profile of the trailing edge, then it is done that way to balance area above and below the vertical CG as well as reduce some of the forces generated further out from the vertical CG. If the trailing edge was straight, might work fine or even the same . I prefer this layout though for looks and to satisfy my engineering appetite.
