Kieth, If you look carefully at one of the close-up pics ( http://www.piteba.com/eng/index_eng.htm about halfway down) there is a hole in the side of the reducer nipple (black iron, 1.5", about 0.90$US) that the cake is squeezed out of around the adjustment screw. the only reason i could think the price would be so high is the welding costs, a trained welder would demand a lot of money for their work, even as simple as this. and as for continuity, it wouldnt be perfect, but the oil could be drawn off by funnel, and the cake could be shunted to a bigger basket as it falls. ill see if i can get something put together for you in the near future, i doubt ill have any numbers, but i can have a diagram pretty quick.
