Sanding Filler

I started today by sanding the filler from yesterday. This fiberglass work is a lot like drywall- one layer at a time makes it smooth in the end. While we were at the picnic I asked Bob about how he makes the mating surface of the exhaust flanges flat. He said he uses the belt sander, so I tried the same. It worked very well, though I did have to take a few breaks to let things cool.

I tacked on the flange for the number 3 pipe:

And then continued with headrest lightening holes. I used the step drill to make 3/4″ holes for the punch bolt:

I thought that the finished product turned out fairly well:

I spent a few more hours working on more exhaust pipes and making more pilot lightening holes in the other headrest parts.
