It wasn't me, it was bad cote...

Recall I could not get the cote to shrink. It would just melt and wrinkle up. After several attempts I gave up. I asked John Hayes to help me figure out what was wrong.

I spent a couple of hours with John Hayes at his shop this afternoon. I had so much trouble with the cote work on the cubby, and now on the PT-19, that I asked him to teach me his technique. Turns out it was the cote, and not my technique. He had the same problems with it melting instead of adhering and shrinking properly. He brought out some of his stock and it went perfectly, and quickly. Good as new This is the large patch on the top  He uses a heat gun with a flat focus diffuser instead of an iron on the compound curve. Made short work of it. Incidentally, John gifted me a Top Flite mini-iron for the smaller areas of cote work.

The smaller repair on the underside.

 

I repaired the rondel!

All up and ready to fly!
