Large f'off blowtorch

Just out of interest - how f'off?

I use one of:

http://www.machinemart.co.uk/shop/pr...-long-arm-gas-
torch

However the main attraction of that is comfort working - you can stand
and kick the roll in front of you as you move forward (you play the heat
over top and leading edge of the roll and the surface at the same time
so they both go together hot).

You can easily get enough heat out of a smaller torch with a large end
on it. Say something like:

nozzles

While this is handy for edges, and drips etc, it would not be a easy to
use for larger areas.

Largest on a can, or something that needs a full-on caravan tank of
propane and the torch is on a long rubber hose?

I use the smaller torch on the dinky 4.7 kg propane bottles. The big one
can run at up to 36kW IIRC, so that would probably be better on a 12kg
tank or larger unless you are only doing a couple of rolls.



Thanks John. The top one looks the sort of beastie I've seen roofers using.

For a small shed I could manage with the 2nd.
