Lighting up extension chimney

Post  Willsy on Sun 07 Feb 2016, 12:51 am

With Dad busy fettling and fitting the gears I decided to make a start on the extension chimney.
I purchased a long length of aluminium pipe of good old eBay and today I set about making a tapered collar to fit the pipe and sit inside the chimney.
What sort of length have you made your extension chimneys?????

Here are some photos of the tapered collar I made today

Mine is a 5ft length of gas flue pipe. Works a treat and does not need a fan.

My extension pipe is a piece of 4" dia cardboard carpet roll core, about 30" long. Works perfectly and cost nothing. Very Happy

But Phil The smoke will always get out your chimneys with the fact you live upside down.

Nice to see a well loved grey Super 7 and elegant turning.  

There can be quite a bit if windage on the extension pipe, so it might benefit from some stability further down. This is essential on the showmans's with a spilt chimney as the pipe can lift off the copper top.  I have a stainless steel running chimney (visible in the avatar) that engages below the joint and a carpet tube fits beautifully over that. It also protects the cardboard tube from heat if the blower is on during lighting up.

Hi Tim
I have made the extension pipe to fit down in the chimney by 10" then the collar holds it in place at the top!
Does the extension chimney give a good draw on the fire when you light up?
Would you say a back damper would be useful on the DCC.
You noticed my old super 7 then👍
It took me a long time to find one in that condition and not completely worn out.

Kind regards jon

When lighting up keep thin and airy. If having trouble or on a damp day. Burn a couple fire lighters in the smoke box first to warm up and get the movement.

Thanks Lynn
Had a back damper on our previous engine and it worked very well so might adapt the ash pan to incorporate a back damper.

Cheers

A bank damper might be useful if the engine is facing the wrong way in the wind, but far from essential for the DCC.

With that height Jon, you'll need permission from air traffic control at Newquay. Will the engine be at Bocconnoc?

Going to say my extension is about 5 feet, although nothing as posh as yours, its just a bit of 4" flue with a couple of handles rivited to it.

Longer is better in my view, never have any probs lighting the Burrell up with it Cool
