I replaced my rood skin. used a drill with spot weld removing bit think its called a roto broach?. . drilled about 100 holes around the rain gutter and pulled the roof off. then pulled the gutters while i was there and replaced them too. the new roof was glued on with panel bond with 25 clamps holding it overnight. had to drill my own holes for the air horns and lights.

Roto broach is correct, they are milling bits that cut a clean hole with a centering pin in the middle of the bit/cutter.. jojo

I think Hougen was one of the tool companies. it's been a while for me, I used to use them when I did frame replacements and 'A' frames in Macks..  blast from my past,,, jojo
