Mash tun is now done too.
First up, a simple 25L cooler from Go Outdoors (ã15 with their discount card).
Please excuse the mess on my workbench....
After measuring up, use a 38mm hole cutter to drill through the outer skin of the cooler.
You need to just go through the outer skin and not all the way through.
I then pilot a small hole through the insulation and the inner skin to gt the smaller inner hole lined up right.
A 19mm spade drill from the inside just needs a slight fettling with a scalpel to give a good tight for the thread of a 15mm tank connector.
You need to clear out the insulation out to the size of the outer hole so that the tank connector only fits around the inner skin. If you just drill a 19mm hole through both skins, the flexible nature of the box means you'll never get a seal.
A bit of spanner twirling and we have a valve.
A load of 15mm connectors and tube from Wickes gives a right natty manifold.
It should work pretty well as it conforms to John Palmer's guidelines regarding tube placement.
All set for my Pilsner now. Can't wait.
I think my next project will be a counterflow cooler.....
