Using a disc/belt sander I set the fence again to a 22-degree angle. Using 1” x 1/16” brass stock (purchased at a local Ace Hardware), I ground the angle to match the jig. Using the jig I aligned one side of the brass stock with the jig and took a pencil to draw a line following the jig on the other side.
Grinding flat stock
Next I took a hacksaw to cut outside of the pencil line. Using the disc sander I removed the remaining brass so the brass aligned with each side of the jig. I continued cutting and grinding the remaining three pieces so each piece fit the jig.
Shroud sides supported by the nails
With all four sides resting against the jig I used two small nails on each side of the jig. I bent the nails so they would apply pressure on the brass to hold the brass in place. Using flux and solder for brazing brass I solder the top four corners. Next I removed the shroud from the jig and turned the shroud over and soldered the bottom four corners.
