Went out to the 23 degree garage this morning and cranked up the "Mr. Contractor" propane heater and let it run for a while. I don't think the garage temp ever got above 50 degrees!
But activity is a good way to stay warm, so today I deburred, filed, sanded, and painted all the nose ribs as well as the main spar flanges they attach to. I clecoed the nose ribs back into position and riveted them in place.
After finishing the nose ribs, I set the nose skin into position and clecoed it in a few places so I could clean off all the factory stamps and lines I had drawn on it (using denatured alcohol). Tomorrow I begin final prep of the nose skin ... if it's not too cold!
