    Hi Gents,

    I thought I would post some pics I took of a Prentiss Wabers No. 9 stove that I just recently fettled back to operational readiness (not looks). The thank had a large hole in it that yours truly decorated the tank with. You should be able to see it in the first picture below in the upper right corner. The fuel tank is upside down so you can see the hole in the tank but a bit blurry. I managed to silbraze the tank from the inside and put it back together.

    I was able to pop off the end of the tank, which contained, to my big surprise, the gunky dirt from 85 years of use and abuse. You'll notice the hole in the tank above on top of it. Don't ask how it happened. :oops:

    Here's a closeup of the gunk. I think it is gasoline leftovers and a lot of dirt that didn't get filtered out of the fuel when used.

    Here's a look at the hole from the inside. I was hoping that the first photo above looked better, but it didn't, and that's the breaks.

    Gunk residue in the tank.

    Here's the end cap of the fuel tank all cleaned up. It is soft-soldered on to the tank after a tight fit.

    I silbrazed a piece of brass over the hole on the inside. Why did I silbraze? For some reason the soft solder I had wouldn't stick the brass. After that, I soft-soldered the end cap back on and tried out our system.

    This is the ferocious flame that resulted upon fixing this oldie.




    1365834732-pw-no9_007_800x533.jpg
    Nice and blue.

    A more sub-dued shot.

    The colors just look too good!



    1365834825-pw-no9_013_800x533.jpg
    Another shot. The jet retainer is loose and will need to be tightened or sealed. I tried to just tighten it but the small flame would not go away.


    1365834838-pw-no9_015_800x533.jpg
    Looks good to me.



    1365834857-pw-no9_016_800x533.jpg
    Not too bad.



    1365834890-pw-no9_017_800x533.jpg
    Looks great!



    1365834923-pw-no9_023_800x533.jpg

    Great to get the old thing going Sam. Nice flames. I still have to fix the pin holes in the seam on my #3. Thinking of using acid to clean the area instead of flux and taking the cap off, then just soldering from the outside.

    Thanks guys!

    About putting the cap back on, Duane, I cleaned it off the best I could with some heat and wire brush. I then 'tinned' up the inside of the tank tube and the cap but only a very thin layer. I had to sand a little off just to get the cap back on.

    I also applied flux to the tube and cap before I put them back together. Once on, I stood ready with my solder and torch and heated the joint to set the tinned joint and also applied more solder on top of that as I heated it to make sure there was enough solder to make a good seal. With the flux in the joint, the tinned solder and the extra solder was drawn into the joint even more.

    I checked for leaks and sealed them with more heat and solder.

    Check for leaks in water and pressure looking for air bubbles. None.

    All I have left now is cleanup and polish.

    Hi Sam, excellent fettle on the tank, I am amazed at the amount of gunk that was in the tank.
    The stove must have had many years of hard work with dirty leaded gasoline, The gunk in this tank is the worse I have seen, but now it works superbly with a fantastic blue flame
