Dadsdog,    If you don’t get the link to the 55 gal Airpot, I think Dr of BBQ & myself can help you out.    I have a 55 gal oil drum and with the Doc’s injector, we’ll have you injecting hot coffee into cups in nothing flat.   ….[:D]..[}:)]          …. hummm, I think we could also rig a 55 gal percolator  (or drip system) as a backup just to insure you don’t run out and solve BrickBOO’s aversion to airpot coffee.  … Fresh made!  …
