There are loads of different designs for this vessel. Some people modify coolboxes some have fancy stainless steel affairs but my 2 main aims for this build is it has to be A) cheap and B) effective.

This is by no means a new idea, similar things have been done before by other inventive homebrewers but no ones published it.

For the design I used you will need:

Materials
- 2 x food grade plastic bins with a capacity of 25L each (£8.46 each)
- 1 x ball valve tap (£3.98)
- 1m long piece of 15mm copper pipe (£2 ish)
- 1 x brass tank connector (£0.99)
- 1 x 15mm -15mm compression elbow (£0.68)
- Insulation of some sort (mine was Aluminium Thermal Foil at £9.98 for 60cm x 7.5m)
- Silver waterproof tape (£1.10)
- 1/2" food grade tubing (not essential but useful) (£0.99/m)
- I used an extra female to 15mm compression elbow but its not necessary. (£1.28)
- I also used a bit of PTFE tape but its not essential ( I had some kicking about but this stuff is crazy cheap)

     Total cost = £35.65 (£37.92 with extras)... but you'll use leftovers in the rest of the brewery build!

Tools
- Pen or pencil.
- Drill/rotary tool with a 2mm bit and a routing bit.
- 2 adjustable wrenches.
- Scissors.
- A pipe cutter or hack saw or some way of cutting copper pipe.

This instructable requires sharp things, spinney things and cutty things. Please be careful at all times. The 'golden rule' of homebrew - "always drink a homebrew when doing anything to do with homebrew" - should not be observed if you are going to use any of the above mentioned spinney/sharp/cutty things.

This mash tun will only make non alcoholic malt extract so I'm fairly sure anyone can make it but adding yeast to ferment this would make alcohol. This is legal here in the UK but if you're not sure, check your local laws. I take no responsibilities for any fingers, limbs, lives, marbles, virginities, sights, sanities or freedoms lost. Or anything else for that matter!

I would. I have loads of bubble wrap from packing in big pieces. Thermal foil can be bought in the form of 'space blankets' or 'survival blankets' from pound shops, though I stockpiled mine from tesco in a sale. I have combined them into insulation in a 'haybox' style cooker before.
