More shiny bits,

Most of the hard piping is complete and the mash tun mixer finished with the wort return from the heat exchanger going through a radial banjo fitting and up the drive shaft.  Hopefully this will provide an even flow back into the top of the mash. The lauter grant is finished with its breather pipe extending to the height of the mash tun. Hop filter needs to be raised to enable the lid to be removed mid boil.
