    Yep, that bung in the top where the burner valve fits is apparently not tight!:rage:

    Back to the old drawing board...:mrgreen:

    Hi friends!

    I recently aqquired this Optimus 200P with a big dent at the top of it.
    The plan is to use the freezing metod to remove the big top dent and maybe reduce the one on the side of the tank.

    But how to seal it so that preassure of the freezing water can perform its magic? Am i supposed to let the carburator stay?

    Regards Matti Kucer

    @Matti Kucer
    The crease type dent maybe hard to remove because the crease in itself is quite structurally strong. However it’s certainly worth a try.
    My preference is to remove the valve assembly and use a fitting with the same thread as a plug. All openings into the fount must be closed, water tight. I do leave the pump with it’s NRV installed because in my method it’s frozen first in the bottom half.
    Good luck with the dent removal.
    Cheers
    Pete

    The tank is now in the freezer -18C for the first part of the operation. I cut of some 5cm from the valve assembly and sealed it by soldering the end. I believe that the cut off part can be restored again later.

    I will continue with part two tomorrow evening.

    Here, the shortened and sealed/soldered lower part of the valve assembly. Now in the freezer for the initial hour. Then 30-45 minutes additional freezing for the magic to occur.

    Having access to a freezer with a clear window would make the method even safer :)

    Hi all!

    Due to my late start friday evening I had to abort long after midnight, it was time to go to bed.
    I then restarted step 1 during saturday.
    With the base frozen I filled it today, waited 1 hour and 10 minutes.
    CAUTION! In this case the time was perfect, the dent in the uppger part was gone. However, the power of the expanding water is extreme.

    Here it is in a bucket filled with hot water.

    Well, Yes. That sharp type of dent wont go this way. Only dents in the upper part.

    I guess this lantern was dropped at some point.

    @Matti Kucer Well done.
    As you know, I have used this method of dent removal quite a bit, mostly for when the top of the fount has been pushed in. I have have very good success. Now yours with a upper side dent removal success adds to the usefulness of this method.
    Cheers
    Pete

    I have borrowed some sticks for automotive dent repairs. Will try and see if I can reach the remaining dents.

    I needed something hard that had a good tip to bend with, so i found a garden tool wallhanger that was useful. Managed to reduce the sharp dent. Its still there though.
