Yesterday, I got the fabric plates installed with the cut out for the wires. I Hysol'd the tail light housing in place on the fabric plates, clamped it and left it to cure. This morning, I noticed that there were some stress cracks because the part did not fit my rudder exactly (this is a Kitfox part I have modified to fit). This actually is ok because the cracks relieved the stress on the part.
So, I filled the joints with SuperFil and let that set over night. Then I began filing, sanding and shaping into the final form. I taped up the rudder and sprayed a couple of coats of primer on the unit. It's ready for cover and paint.
