Been lurkinghere a few weeks now and posted in another thread. So iwatched some pitmasters then googled and found this site. I bought a cheap(ish) offset from ebay and it is actually well made, bu-ger to ikea as it was flat packed but it was almost right just a few bits left over.
I did a cook/test burn and boy was it fun(not) the temps were wild from 90 to 300 ish. Seemed the ash and small bits of lump were dropping under the grate and stopping air flow. Cleared that and got the temps stable. must have got some high temps in the box as the grate melted
