    Yesterday I tested the funnel using that arrangement...found one lite lick..re soldered and checked again!!!
    [​IMG]
    Quite impossible to go around the funnel without temptation...The devil was a winner!! I used those torch combined...the bigger for color the powerfull for distributing the silver...
    [​IMG]
    that was the result on the top...
    [​IMG]
    and reverse side
    [​IMG]
    Now I have to wait for the 25 mm new torch... :-\ :-\ :-\

    Yeah, that is looking good Paolo, Good luck with your pressure test, it appears though tht you should be in good shape, the joints look good visually. Amazing isn't it, what higher heat can do. Yeah, you should be making pressure before you know it. ;D ;D

    Paolo,

    Boiler looks great. Thanks for posting this. I'm struggling with the silver solder process and your posts have given me a lot of insight and confidence that I'll eventually get it.

    Regards,
    Dennis

    Yesterday I had a stupid social event and I wasn't able to finish my tube bendere!! Today all was done and the copper tube was ready for connecting the pump to the boiler. After few strokes, the boiler was filled before, I reached 10 bars of pressure but the pressure dropped quickly at 8bar and half:
    [​IMG]
    I noticed a little seep from the pump
    [​IMG]
    tightened the elbow the pressure was dropping again...after a deep check I discovered two drops of water from here:
    [​IMG]
    and here:
    [​IMG]
    Fortunately the cross tube are externals ..."Coraggio" (Urry Up) I said and I started another silver soldering session :big: :big: :big:. Now the boiler is into citric acid. Tomorrow the sentence!!!

    Your 'intestinal fortitude' shall overcome these annoying problems. Man, I have to hand it to you for staying the course. When it is all done, you will have a fine looking boiler. Carry on soldier. ;D
