As I’m gearing up to install my wing leading edge landing/wig-wag lights I need a quick way to identify 67°, which is of course parallel to aircraft centerline.  It’s also the same angle that we install our vortilons on the wings’ leading edges.  Of course in the Roncz canard plans there is an included outline of a Vortilon Installation Jig, which I made up way back in 2012.  But with it having been drenched in the hurricane/tornado that hit my old hangar, it’s seen better days.

I also wanted something that carried that 67° both up & down vertically, as well as over/ under the wing a bit for easier vertical alignment when I install the vortilons. With vertical tabs of the jig 90° to the horizontal leading edge segment it will also allow me to mark the edges of the wing leading edge light pocket.  So I ginned up a new and improved jig in rather short order in CAD, and 3D printed it out.  Not bad and it works as designed!

I then got around to knocking down the micro’d aft vertical and underside trailing edge of the top cowling on both sides with 80 grit sandpaper on the orbital sander.  I then switched to a sanding board to hand sand the left side (pic 1) and the right (pic 2)… with both sides looking obviously much better than pre-micro.

Another couple shots of the sanded micro on the aft end of the top cowling, on the left side (pic 1) and the right (pic 2).

I’m still getting a slight bit of oil canning on the right side shoulder bump, where the upper cowling is secured to the bird.  So on the CAMLOC flange I added a single ply of BID, 2.5″ wide and peel plied the layup.

On the inside lip of the top cowling I added 2 plies of carbon fiber: the first 2.5″ wide and the next 1.5″ wide.  I then peel plied that layup as well.  Tomorrow I’ll redrill the CAMLOC holes and see if my added glass/CF eliminates the oil canning.

Tonight is a date night with Jess, and having gotten a late start on the bird this afternoon, I wanted to get some epoxy curing… so my next and final task for the evening was whipping up some micro/West 410 and applying it all along the underside of the strake leading edge, both on the right strake here and the left as well.

I then closed up shop and headed for a nice evening out with Jess.

Rock n’ roll!
