HOn2½ Box Cabs - "The Twins"

With one side held solidly with solder, solder the other side.

Apply heat.

Test fit into shell.

I drew the roof in my CAD program and printed it out.
The paper print was glued to a piece of .010" thick brass
sheet using spray adhesive.

After cutting along the lines carefully with a pair of
Fiskar scissors a file was use to trim to the line.

Next a piece of pipe was used to start the curved roof.
Anything will do that is smaller in diameter than the finished roof curve. The pipe was used to start the
bend. It gave a gentle curve to the roof, but I
needed more curvature.

Next I used a pill bottle for more curvature.

A quick calibrated eye ball look said it was close.

A test fit on the roof ribs showed I had just what I wanted. A bit of a tighter curvature than the roof ribs. When pressed down in the center the roof conforms to the curvature of the ribs as will be seen in later pictures.

I started with the center rib to solder the roof on. A bit of flux. Same procedure as when I soldered the middle rib on. I scribed some lines near the end of the roof to help center the roof front to back.
