Lets build a camelback,, or two.

My next step was to solder it in place. I cleaned the front edge of the smoke box and back side on the box front with some fine emery paper and applied some flux to both surfaces.     I lined it up and temporarily held it in place with some painters tape. This allowed me to use both hands to run a bead of solder around the whole smoke box.


I then cleaned up the excess solder with a bunch of small files. In this step you have to be careful not to file off the rivets on the smoke box.    



Next you wipe off the smoke box front with some rubbing alcohol to get rid of any flux residue. You do this so that you can glue the door from the original box front in place with some CA glue.
