Installing a new canard (transferring existing fuse holes)

CP47 Page 9

Judge King, Long-EZ N350JK has just completed his new R1145MS canard,
which he retro-fitted to his Long-EZ. He has an easy way to transfer
the existing 1/4" diameter holes in the F-22 bulkhead to the aft face
of the new undrilled NC-CLT aluminum lift tabs.

1. Fit your new canard per plans, be sure the water line is level with
the top longeron level (correct incidence).
2. Remove the canard and paint a thin film of oil around the hole in
the F-22 bulkhead. Spray a coat of any color paint on top of this oil
film about 2" diameter around the 1/4" holes.
3. Obtain some foam tape with stick on both sides (1/8" thick 3M
double stick foam tape works great). Stick this on the aft face of the
NC-CLT lift tab centered roughly over the area where the hole will be.
4. Install the canard and clamp the NC-CLT lift tabs firmly against
the F-22. Remove the canard. The paint will now be on the sticky
surface of the foam tape and a perfect impression of the 1/4" diameter
hole will be clearly visible.
5. Now make a drill guide out of 1 1/2" x 1 1/2" piece of 1/8"
aluminum scrap. Drill a 1/4" diameter hole through it. Lay it on the
foam tape, exactly centering the guide hole over the paint impression
location of the hole. Clamp this drill guide to the NC-CLT using two
small 'C' clamps.
6. Drill through the drill guide, through the foam tape and through
the NC-CLT, both left and right and presto! You have a perfectly
matched canard to F-22 bulkhead.
