Title: Re: Building a chuff pot
Post by: St Paul Steam on November 25, 2024, 07:30:40 pm
Geoff (Oz steam demon) used a custom chuff enhancer that he made that had similarities to a whistle, usually (preferably) mounted in the chimney close to the large chamber beneath in order to capitalize on the echo Chamber effect found below.

Looks a little small for a reservoir, or even a boiler for that matter. As a chuff pot, I'd consider putting your steam entrance nipple low on the chimney with a hook pointing down into the main body of the "pot". I think your chances of significantly enhancing the chuff are best served that way, but it is probably something of a crapshoot as to whether you actually gain anything or not?!?!

  I came across a Lenk torch whose burner was in rough shape
so I thought I might turn it into a chuff pot.  It has a
nice removable screw-plug in the bottom so I can easily
drain it.  I will drill a small hole for a 3/16" nipple
to route the steam into the barrel and as you can see from
the photo I already have a brass pipe that fits perfectly
in the top.

  I'd like to maximize the chance that I can enhance the
'chuffing' exhaust sound.  So, does it matter how long the
stack is and should I put the nipple high on the body or
lower?

  Just to put this into perspective, I also thought about
turning it into a small 'center flue' boiler or a water
reservoir for engines with a refilling 'force pump'.  Hmmmm.

Thanks,
