End2end, that’s very interesting and something I must bear in mind when I reach the stage of populating the layout.

I have said my piece, as far as I am concerned, sorted.

Complex. :shock: :lol:
Is there a way to slow down the flow of smoke through that Timbersurf?
Also on the houses it does come out in quite a fast straight stream. Is there a way to add something within the chimney to break the stream up?
Say a criss-cross grid made from a peice of food/tea strainer perhaps?
Thanks

Its not a question of slowing it down, the pump has a fixed output (only slightly varied by the supply voltage), thus if restricted by 4 very small holes, ends up as jets of high speed smoke! I fitted a leak (tee piece with a restriction on the side outlet) to the pump output (before it reaches the smoke generator pot), so I can reduce the flow of air to the generator. It results in more of a realistic dribble of smoke, but is finicky to set the balance of pressure.
