Sweet!  :ThumbsUp:  Love your narration, Thomas, and that is one sweet running engine.  Sounds like it's time for a shot of your best bourbon.

Hey Bent and thank you, had several after that run.

Added the longer hub on the flywheel this morning and put two set screws in it instead of one. Figured that much weight needed a bit more grip.

Have a great day,
Thomas

Hello everyone,

I have been experimenting with various designs for a muffler to put on my No.4 engine. I wanted to improve the sound and increase the volume so that the exhaust could be heard from a distance when the engine was running real slow. I built 6 different ones and used steel, brass and aluminum in different lengths. This one on now is the best so far and it is made from aluminum bar, tapped one end 10-40 and over bored the other end .375". I believe it has helped a lot and I should be even better when I run it on steam.

Good day to all,

A good friend and fellow machinist, David, has just completed the first ( to my knowledge ) one of a Steam Engine No.4 from my free plans. He states it runs very smooth and quite slow on about 2 pounds of air pressure. He plans to leave it in the natural metal finish and will install the center crankshaft support soon.

Looks like he has done a really nice job and some beautiful machine work.

Have a great day,
Thomas

Hello everyone,

Another #4 Steam engine is now completed and running. Note that JR used the optional “straight” valve design and a much lighter flywheel, but as you can see it is a really smooth runner. He also chose not install the center post support which is not required. He has done some beautiful machine work on this engine.

Hello everyone,

It has been brought to my attention that the Google link for the free plans to Steam Engine No.4 posted on reply #66 no longer works. Not sure what Google has done but I cannot access my account. I will up load the first 8 drawings here in a pdf. format so they can easily be copied. I will upload more on the next reply.

Have a great day,
Thomas
