Hi Brian.

Quite like the idea. How is the swiveling part with the wind vane fixed to the extension. Is it just pushed on and if so does it not blow off when on the move?

Cheers. Whisky. scratch head

Hi Wiskey and Roli,
Here is an exploded photo of the cowl, I dont think that it would blow off with that much up inside, held down by the weight of the vane which is 12in x 61/2 of 18guage steel held on by 2 poprivets, The bottom of it sits on a plywood washer faced with another washer made of the same steel as the vane, because I felt that there might be too much friction between the plastic pipe and the wooden washer to enable it to rotate freely. If I have any trouble with rotation when winds are not strong enough to turn it but strong enough to blow the fire out I have a piece of dowel with a hook on it so that I can rotate it through the Heiki.

Cheers

Brian


Ps I do not plan to leave it on when on the move so I will have to carry the luton ladder suitably padded to enable me to get at it

Hi Wiskey,
I decided after your comment, to tie the cowl down with a long piece of nylon cord in case I forgot to remove to go on the road, and it did blow off, this is about a yard long to allow for variable winds turning it round and round when unattended.
