Title: Steam siren
Post by: Powder Keg on July 26, 2008, 11:37:11 AM
I never ever even thought of building one of these. Until a chap from the UK sent me some plans for one. There are only a few parts so I thought I would build one in my spare time. Friday after work I cut out the lever, that opens the valve, on the CNC mill. The original plans were quarter scale. I'm doubling everything for a half scale version. It's still pretty small. It looks like a fairly straight forward project. Compromising of mainly lathe work there are only a couple pieces that require a mill.

Here is the lever that I made.

I'll update this as photos become available:o)

Managed to squeze a bit of work on this in today. I started on the valve body. This is the bottom end. It will have a 1" hex machined on the end of it.

I have to drill and tap the end for a 1/2" pipe thread. I like to do that first, While I still have something substantial to hold onto.

Later, Wes

I thhink these are fairly unusual? I have never seen or heard one before. Better reason for me to make one:o0

Later, Wes

I Think part of the fun in building something is researching it. Here is another Video. I think these guys were having a bit of fun:o)

Very very cool.

I bored the end for a 1/2" pipe tap and tapped it. Notice the marks on the tap so I can gauge when I'm getting close to the bottom.

After I finished taping the piece, I cut the part off the shaft with my bandsaw. I chucked it back up and faced it to length and bored the different steps that were required.

I then started on the body of the siren. It is a tube that is bored on one end to get silver soldered to the valve and the other end is threaded, so the rotor can be removed for cleaning.

That's all for now.

Had a small Snafo  this weekend and needed something to do. I saw my Siren parts lying there and decided I needed to revive this thread\o/ It was a pretty lazy day today but I needed to accomplish something. I cut the hex into the bottom of the siren this will allow it to be tightened onto a steam/air pipe.

I need to find a couple of 1/8" endmills to mill the turbine slots. that should be fun:o)

Yea, Me too. I vowed not to tart any more projects till I finished three that were ongoing. Unless they pertained to something that I was building.

Things are kind of slow so I was reading some of the old posts. This one sounded interesting. Just wondering if you ever made any more progress on it?  :D :D

Cheers  :beer:

Looking good so far - where did you get the plans? I have been keeping my eye out but not really looking, but would love to make a third scale one to go on a traction engine.

I'll second the request for the drawings. I am ready to machine a whistle or siren for my own TE. I'll post the build pics if anyone can supply the plans.
