First attempt(whilst at work) to work out the principles.
Just got to find some suitable pipe(68mm. o.d.) as a pattern, think I've got some somewhere

Spray can? It isn't a problem if it is a bit smaller you can bend it out en weld it up.

Good tip! I found some copper tube that's slightly smaller which'll do.

Well Pete, if you'd seen my ally welding all of 30+ years ago it might have been possible and tempting though it is to find a tig set I can't store any more stuff!

Only -10 last night so time to bring the flamer in from the cold and ready for building up:trouble is, bits/parts have been mislaid over the interminable years this flamin' project has been boring the a**e off everyone so I'll be much more concise in future .

The unit has a fair bit of oil and dirt on it, best thing to clean it with?
The two leads have lost the insulation, best and easiest fix?
for those of you in Belgium, the BBC tells me that your Telegram service is about to close stop.
Did a continuity test, ok.
