Home made mash tun

[chris_reboot]

thanks fella.
that's the only thing holding me back from ordering one.

the coolbox I have is well insulated all round *except* the lid, so it would be nice to get that too without drilling and foam filling it.

I have one of these:

Has a hollow lid and I've never added more insulation. Have never lost more than 1c/2c over the course of 90 mins.

looks pretty similar to the coleman one earlier in the thread.
nice one.

My Coleman cooler arrived, and it's a beauty. I'll get some pics up tonight or tomorrow.

It has two features that are very promising.

First of all it has 1 gallon increments on the inside that are marked by a small step reduction of diameter. The means there's a perfect shelf for a round false bottom.

Secondly, it has a lovely channel moulded in at the bottom where the tap is.

Now, my problem will be finding a round plate of exactly the right size, and measuring the internal diameter accurately is tricky.

Hello. Reading your posts with interest. To avoid filing the centre of your tank connector out i just pushed my 15mm pipe into the end with the 2 little lumps and soldiered it straight in. It seems to work. Also been looking at at compression or quick fit straight and elbow joints with male and female threads to join a false bottom to the side of my FV and then to a ball value.↲Mark

two sicks put them inside and mark both of them where the cross if you make the sticks with arrow heads you will get a very accurare measurement. I use this method when working out out of true wall recces for shelves always works

Hi - first post on here.

I've got two of these sitting in the shed and was planning on converting one into a mash tun.

I was wondering if the other could be used as a boiler or if there is any issue with the plastic not being resistant to those kinds of temperatures?

[Mitchamitri]

Ideal as a mash tun but I wouldn’t use one as a boiler.

Jusr been looking at wetdogs picture of his ball valve set-up; very professional it looks too. My questions is whether any one out there has used this on the Coleman cooler we've discussed through this thread, and if so, has it required any alteration of the coller itself; you know, increasing the size of the hole either inside or out?

[borischarlton]

It requires no alteration at all, I even used the food grade squashy washer the comes with the original tap.
I have done a few brews in mine now and am well happy with it

That's great news boris! Can I ask where you got your bits 'n' pieces from? I'm also interested to know what you used for a grain stopper given that this has clearly worked out well for you. Thanks for the assistance btw!

This is the thread you want, it explains it all. I made a simple copper manifold which leaves just a cupfull of dead space

[Beer Bomb]

Bugger .......
Just tried to order one of them coleman 10 galloon cool boxes only to discover that they have sold out and no more are on order.
Anyone got one for sale or know of where they can be had for a similar price?

Cheers

Hi guys,

I got the 10 gallon coleman in this thread before Christmas, and I have finally gotten round to converting it to a mash tun. I wanted it to have a false bottom, but I am absolutely crap at DIY so I did the following:









I used some thick braided, food safe hose on the bottom and siliconed it in place with food safe silicon. I then got one of the stainless BBQ grills from Wilkinsons that someone on here linked to, and folded it to the right shape. I then drilled a hole in the centre and fitted a little bolt/nut to stop it bending under the weight of the grains.

The weight of the grains will keep it sealed against the pipe, and as I only ever batch sparge, by the time I have recirculated the first few litres, it will be sitting flush under the grains and any grain that did get through will be returned to the top of the mash tun.

Total cost, excluding the thermos box, was £7.

Anybody see anything glaringly obvious I have missed?

G.

i trust the hose is drilled to be the manifold? What was the make of the food safe silicone?
