ok, shame on me..........
i completely overlooked the screw in the middle to undo the rest of the frame.
once i did i could turn the metal tub that's connected to the gasket. and it now doesn' loose pressure anymore..
the leather in the pomp is still fatty thanks to the vaseline i put on, and pumps better than before, (3 out of 5 pumps it works), but still not 100%
someone wrote me about turning the leather ring, but i'm not sure how to go about that.
in any case, at least it works now!
thanks!!!
ps. i only saw yesterday that i can buy lamps directly of pelam too, i am concidering a smaller second one.
i have a big camper truck, and would like to use it indoors. if i let enough fresh air come into the camper, should that be fine?
