And how the valve would go together: |

I'm waiting for gauges to arrive, since I want to hydrostatic test the boiler, check the pop off of any relief valve used, And will also have a gauge attached when working. I'm hoping to be able to run 20 lbs pressure with this boiler. From a little Internet research, 2" electrically welded steel pipe -- sch 40 -- has a working rating of 1500 psi. It is pierced and tapped however in this design which would reduce that, and the sch 40 CI pipe caps have a working rating of only 150 psi. So what I'd like to do is hydrostatic test the finished boiler to 150 psi and hold for a half hour. That should give me a reasonable degree of confidence for 20 PSI in use. One aspect of this boiler that I do like quite a bit is the ability to remove the caps and inspect and clean it periodically. And the ability to replace the copper water tubes easily. |

Steve To limit where silver solder flows to make critical or neat joints use Tippex type writer correction fluid. The solder will not wet where the chalky deposit is left |

I'll remember that, Andrew. I guess that must be the same thing as WhiteOut here. Today was Fun With Sheet Metal Day! I managed only one small cut on the back of the thumb.....I did everything with snips and a couple of pieces of angle iron clamped in the vise by way of a bending brake. The boiler base came together surprisingly well, for me. I have hardly ever worked in the stuff, and this was pretty heavy gauge metal I had lying out back. A good day! :beer: |
