so I got my spare 44gal drum and the angle grinder and....

As a comparison on 40 litre TPW strip runs, I found
Without insulating drum it took 60 minutes from start to foreshots; with drum on (as per picture) it took 35 minutes to foreshots.
Without insulating drum the strip was about 4.9l per hour with all three ring burners on (maximum); with drum it was about 5.2l per hour with only the large and small rings on and, at a guess, it ran at around 6.5l per hour with all three burners going (didn't do this for too long as I figured it might be stripping too quickly for a suitable lowwines collection...but NFI really :oops: ).
Anyway as a free solution to my need here its all good IMO :handgestures-thumbupleft:... NO chance of the drum catching fire PLUS it reduces the chance for ingress of flammable material into flame area (eg dust, assorted shed floor crap, small furry aminals, maybe even alcohol vapours) and, of course, it results in considerable LPG usage savings over time.
