Nicely engineered install jhish!
You must have a cheap supply of Class D Div III instrumentation, and gear boxes as well.
One note to folks about augers the open center 5" helix used on the AA style boilers can be adapted to other installations and takes less power to turn by a factor of 3 or 4. You can buy helix and make your own fairly easily, just have to be handy with welding and fabrication of metal.http://www.washburncompany.com/Auger_flighting.htm
Will get some pics of the flex auger I have shortly.
