I'm looking into making a jump to both a 10g system and doing all grain.

I can't seem to find any good argument not to just use a cooler if you don't intend to step mash.

Ideally i'd like to be able to step mash so i've been considering a keggle or other pot for the mash tun.

That in mind, the benifit of insulation has come up. Unfortunatly most your heat lost due to convection through the side is on the lower end of the pot and also the heat source. You don't want your insulation to burn.

One ideais a sleave, if/when you fire the burner it will be removed totally
Thinking of using rigid insulation board, 2 layers (stager seam overlaps) The corners of the inside can given a diagnol piece that is vertically scored to curve to make a more round chamber to conform to the mash tun. 'Wall paper' the insides with tyvek. Use a heat resilant mastic.

coordinate the size of it with your brew scupture.

hummm, thats a good idea too, just removable insulation. I had a little trouble visualizing your exact design. If you feel like drawing it up, I am sure more than one person on here would benefit from it.

I have used both coolers and keggles. When I went to 15 gallon batches I switched to using a 30 gallon HDPE drum for a mash tun. It is very thick (2.2 mm) high density polyethylene. They are food grade and hold heat much better than stainless steel. They are light and easy to clean. Their thick single wall makes them very easy to install a weldless bulkhead. You can pick them up cheap on ebay. In fact, the shipping is usually more than the drum itself. I bought a closed head drum and I cut the lid off about 2 inches down from the top (most narrow point). I then cut off a band of plastic to reduce the barrel height. The lid slips in quite nicely for a secure fit. It is by the nicest mash tun I have used. They come in different varieties (open and closed head) and in 15, 20, 30 and 55 gallon sizes. see the following link:
