Where can I find hollow chimney stacks?

Chris,

Years ago I ran into the same problem, twice. The first was easiest. I used evergreen plastic tubes to create old fashioned stove-pipes. The second involved drilling out the solid resin pieces on a drill press. Good Luck!

Chimney stacks or large round tube like capped vents?

I put a set of these on my 2 stall roundhouse.  Having the inside extensions should help exhaust the smoke from a fan driven unit rather than it fogging the engine shed interior.

I'm with Pappy, drill them out.  I did this for a shorter stack, how tall do you want these?  If they're pretty long, it may take several tries to keep the drill centered for the entire length.

What about making your own with copper pipe? Just a thought. 

All good ideas guy's.  I have a small drill press but I'll leave that as my last resort. small copper pipe might not look bad either. 

Brass tubing is available up to some pretty good sizes - making and attaching a cap should not be all that hard to do.

What size copper tube do you think would look right? 

Not having any idea what the engine shed looks like, I'm a little hard pressed to make that guess.  Having sated that though, I've got some 1/2" that I'm going to use on the one I'm building now for a review in OST.

The shed is the Menards engine shed I have in another post. 

Fairly modern then.....somebody was selling roof vents that had fans in them that actually turned - Model Tech?  Maybe those would be worth looking into? 

 

I'd just stick with the brass tubing and make the vent caps, but then my engine shed is probably 100 years older in era.

How about a large stack, here's the prototype to copy from.

Call Harry Heike, I believe his are hollow and very well detailed

I got ours from Dave at Crescent Locomotive Works, complete with smoke hood for the inside of the building.

Not to be a boo-bear about this, but I'm suspecting a couple of speed-bumps in your plan....

 

1) You're going to have an engine shed full of smoke more copious than the amount escaping through your (1:48) roof vents.  Most modern day 'smokers' having the best smoke fluids for layout running effect, will crank out a lot of smoke even at idle.  Of course you, as I understand it, you can TMCC/Legacy or DCS this down to a lower volume...if you're so inclined. 

 

2) How closely the engine smokestack is aligned with the roof vent...unless you add some collector hood thingy inside....will probably add to the +/- of success

 

3) Re #1 above, you'll accumulate a lot more smoke residue on the engine externals than when running on the open road.  That means more frequent cleaning of the entire engine.

 

4) Using a more modest separate static smoke unit...e.g., as Seuthe makes/markets... in the roof vent which can be turned on when an engine is parked inside, turned off when not...would be my better choice for this effect. 

 

But, that's just MHO. 

 

You could do some simulation with a cardboard box, paper tubes, etc., before spending a lot of time/$$ otherwise.  I would.

 

FWIW, always...

 

 

i haven't overthought this project the stacks are just intended for affect and I don't plan on keeping the smoke unit running inside the shed for any length of time. 

I got these from grant line in o gage

Those look good.  Do you have a link?  Thanks. 

It is grantline.com I don't know how to make it a link
