I have got all my plates drilled and down pipes soldered in, just want to run the build past you before I solder the plates to the bottom of each section.
I am going to use 3 x reflux centring rings - 2 of them will be in the form of perf plates draining on to the packing below, the bottom one will just be a concaved plate with large holes in it.
The bottom of the column will be a 600mm section of 4" with 2 perf plates to act as 2 large Reservoirs to feed the 3" section.
Any bad ideas jumping out at you before I solder it up??
(trying the 4" product condenser, if it does not work I will do a coil)
