    Hi all,

    I finally received my Samigon SS tank. For some reason it took two months by air mail.

    Anyway, I cannot seem to work out how to open it. The lid appears to snap on. I cannot move it at all. Or does it actually screw on??

    Any help would be appreciated.

    I should clarify this. The pouring cap opens fine - it has a bit which juts out which you can lever up. But the whole lid itself does not want to move.

    One of my tanks is a Samigon, just pull the top off. It's a pretty snug fit, but not a screw on. I have to add, though, I thought their 120 ss reels sucked! The clips aren't tight enough to hold the film in place. (I know... stick with Hewes for reels!!) Good luck.

    As others have said, the top is supposed to pull off. If it won't, pouring boiling water over the top only and then quickly pulling the top upwards (holding it with a cloth) should shift it.

    I've rubbed paraffin wax around the edge, sometimes it helps a little bit..
    If I really can't get the lid off, I use a church key(bottle opener) edge..
    Messy but works..

    I think I have a samigon as well but I notice that if I pull the little pourer cap off, I can take the lid off easier. I think that makes air go in and does something to the pressure.

    If the lid has gotten wedged on in shipping, it may be very hard to remove initially but still operate normally once you get it loose. If you have one, you might try one of those jar lid openers, a textured rubber sheet that lets you grip an object with more friction than your skin will provide; use that to hold the lid, while holding the tank body in your hand, and twist while lifting the lid away from the tank. Failing that, filling the tank with warm to hot soapy water and then drying the exterior (to restore gripping ability) might expand and lubricate things enough to get the top off. Do rinse thoroughly afterward, of course...

    Note that heating the whole tank will slightly loosen the lid, because the lid, a slightly larger diameter, will expand more than the tank at the same temperature. Heating only the lid would be better, but is very hard to manage when the parts are tightly joined.

    If all else fails, a scrap of wood driven with a light hammer can be used to drive up the edge of the lid, working around to even out the movement (though this option really requires 3-4 hands). Using a wood scrap instead of, say, a screwdriver will reduce the chance of bending the lid's rim and permanently damaging the tank.

    Actually not too hard - just boil a pan of water, hold the tank upside down and dip the lid only into the water for about 30 sec.!

    Thanks all so far. It's still stuck. I had tried the heating just the lid only. Then I tried filling the inside with cold water and heating the lid. Now I'm trying the soapy water.

    David, I'll be trying your dipping method next. :smile:

    Thanks again to all. Much appreciated.

    Well, if all else fails, you could drill a one inch hole through the bottom and slide a length of closet rod into the hole, then use the rod to knock the lid off. This will, however probably make the tank leak, and might damage the reel inside (if there is one). :wink:

    More seriously, you might try putting the whole tank in the oven and heating it to 400 F, then try opening it (with suitable insulation for your hands, of course). This will a) expand the lid more than the tank, and b) destroy any glue that might have found its way between lid and tank; expoxy softens as this temperature, if it doesn't just outright char, and even cyanoacrylate will lose enough strength you'll be able to twist the pieces apart (probably). If this fails, then dip the bottom in ice water and quickly try again.

    The heat will NOT hurt a stainless tank or reel, as long as you don't go above 450 F.

    It's off!!!! Whoohoooo. The funny thing is, I think it was a bit of a combination of several of your methods which did the trick. I tried the hitting gently with a bit of wood, and that seemed to very slightly prise it open on one side, and in fact some of the soapy water came out of the joint. Then I tried heating the lid again with cold water inside. We went out for several hours and when I got home I picked up the tank. As soon as I touched the lid it almost slid off. Thanks all. :smile:

    That's great Keith. I was just about to suggest the angle grinder method or even a controlled explosion - happily, now I don't need to!
