Nothing to add to dog stories. Sorry to hear of all losses. I like dogs except when they bite (Rottweiler, Alsatian and spaniel so far).
One tip for smokers is to grease the rim where the smoker top fits over the cylinder - with a very small amount of copper grease. (as in cars).. Yes, the grease burns off, but you are left with a thin (very) layer of copper which aids closing and helps prevent sooting up.
Of course, the rim must be clean first and you need to do it every 4-6 weeks but it makes life easier.. I also use a tin can cylinder - removed to light with a blowtorch at the base... no faffing around... And I have realigned the smoker vent in the bellows so it is now directly aligned with the hole in the cylinder and done the D Cushman funnel mod . As a result, my bellows are far more effective.. so less effort needed.
I have a small pile of branches in the garden seasoning for smoker fuel..(Free - I'm not a exiled Scot for nothing)
