I spent this weekend soldering the tubes into the tube plates. In addition, the bushing and extension for the safety valve were soldered in. I used silverflow55 and tenacity flux. Having learned my lesson last time, I broke out the turbotorch to get enough heat. I don’t know why but I always have trouble with the amount of solder to use. On attempt one I didn’t use enough and I had bare patches. Naturally on my second attempt I overdid it. Here is a picture after pickling.
Till next time.

The temperature in the garage was warm enough for me to get some more done on this today. The first thing I did was to glue a copy of the template onto the boiler shell and drill the holes for all of the fittings.
Next I slid in the tube assembly and held it in place with some sheet metal clamps. Then I drilled the four holes nearest the clamps and used my cleco clamps to hold the parts together.
Then I moved the clamps over one and drilled the next hole repeating until I got all of the holes drilled and clamped. The purpose of the clamp to to keep the tube plate from bending away from the outer shell as I was drilling the holes.
With the holes drilled I pulled out my rivet squeezer and put in the top row of rivets.
Here is the current state of the boiler.
Till next time
