Lets build a camelback,, or two.

Now it's time to build the firebox section. The first thing I need to do is remove the flange from the forward firebox casting. Normally this lip would fit inside the back of the boiler, but in my case, the lip is the same diameter as the boiler. This means it has to go.     I measured & marked the lip as shown here and remover it with a hobby knife.

The two castings were squared off and glued to the boilers with CA type glue.     This glue joint is only temporary, something stronger will be necessary. you can also see that I also marked a center line down the length of the boiler and smokebox. This will help later in attaching things like the stack & domes. This line will also extend into the firebox.

While the CA sets up I started on making a template from paper for the first layer of the firebox.     The markings on the template really help for lining up all the parts. They denote the front, rear, center, and fold lines for the ash pan supports. Once this was done I used the template to cut 2 sections of brass to match the template and transfer all the marks over to them. As shown in the next pic.     You'll also notice that I added a line if rivets just over the fold lines. This will become bottom section of the firebox that is unlagged. A layer of styrene will be added on top of the firebox latter to provide the bulk for the lagged upper portion. It will stop just short of the rivet line.
