I have recently aquired a snail drum, most of the finish is missing. very light rust pitting in some areas. Anyways i would like to open the drum up for a good cleaning. do i take the screw that removes the handle out only and then remove the handle... it is rusted on at the oment... or do i take off both screws and the handle before poping the top off. this unit has the handle that folds out of the way.Are there any sites that have dissassembly pictures? Can anyone provide me info on reloading one of these babys? The crank is almighty hard due to spring tension... i question if it should be real hard or if perhaps something has gone ary inside. any info appreciated.
