I think you will be much happier having done it the right way Chris. With the loss of pressure due to the leak fixed, the engine should run better as well and maybe even the burner issues will be minimized.Bill
Is that a pin hole at 20 min to the hour tube to end capBe very careful you could be on the road to a big problem the heating cooling cycle to hard solder a leak can keep going .That’s one reason for using comsol
I feel your pain. I'm chasing the same issues on my boiler. Fix one pin hole by reheating and you create another one somwhere else. Jo recommended using a very small pin punch and peening the pin holes closed instead of reheating. I have worked over my boiler that way but I haven't had a chance to retest it yet. You might want to give it a try.Tony
I still have my PMR boiler castings kit in the box and have never built a model size boiler, however, I have been involved with the welding, inspection, and testing of several full size recovery boilers. I'll admit to using every trick in the book to get a successful hydro for the AIs( insurance company and state boiler inspectors ) I have used hot water ( if you knew the right mill person you might even get some really hot water) I have peened, I have used straight polarity on a reverse polarity electrode to "blow back " the water and seal up a pinhole, I've tried them all to make deadlines and keep a paycheck ( part of the reason I gave it up) , but, upon getting a successful hydro, we always went back and fixed it the safe and proper way. The rework after the fact was a lot cheaper than holding up a successful hydro. You did the right thing Chris. You aren't constrained by backcharges. Awesome project.Cletus
The next time I am building a boiler I think I will send all the bits to Tennessee to be Tig'ed together! Hmmm... There's a question, can a copper boiler be Tig'ed? Tiggered? Whatever the initials are?

The only trouble Chris........... is that, nowadays, that boiler might come back held together with "Ole Tennessee's Special BBQ sauce"! Jim
