Let's finish up the fuse sides...

Okay once cured drill out the stab adjuster rod holes through the blasa fuse sides with an 1/8" bit - we are currently using the Gator style stab adjusters.

Cut 6 1/4 x 1" strips of .007 carbon I get my carbon lams here - http://www.cstsales.com/carbon_Laminates_36.html CA these across the 6 splices in the 1/4" balsa stringers. Use Mercury's High Performance CA M100XF - this stuff is designed to be used with composites. Fit and trim the 1/8" blasa fuse side splice doublers and glue in place - I use med or thick ca and again Mercury products really work well.

Once you have the carbon strips and balsa doublers glue in place you can trial fit the entire fuse - you can see at this point a jig is not really necessary. There is a slight inward bow between f2 and the firewall but the rest of the fuse is a straight taper.

The final step is to true the edges of the fuse sides. Which is done by edge sanding with a large block sander. What you want to do here is to sand the stingers flat to the fuse edges. Do this by just sanding the stingers down until you start sanding off the laser burn off the balsa fuse side, when done you should have trued sides.

At this point your ready for the jig.
