here is the theory:
making my keggle mt into a percolating recirculation
it has worked with coffee for years and is simple to achieve
taking the top from the keg and essentially turning the dip tube over so it comes out the top and welding it.
then a simple 1/2-3/4 inch whole drilled into the top of the sanke keg lid i.e. perc base.
at the top of the dip tube a simple splatter screen 12" (skillet style) with a whole cut int he middle and mounted to the dip tube, to diffuse
the liquid as it returns into the grain.
of course there would be a lid on the mt to prevent over splatter.
2 piece false bottom cut tightly around the tube
so.. good idea / bad idea
