Re: Rushforth
I LOVE that engine!
What I wouldn't give for something like that scaled up a few sizes.
The whole package is beautiful.

Re: Rushforth
Yes, yes find more Dave.

Iám very interested in that.

Re: Rushforth
Here's some shots of the condenser
1 square foot / HP......OR
.000124 m2 / watt..............
The arrow looking thing at the front is just a fairwater. the copper is made from copper plumbing pipe, with a pin at the front that fits into a hole in the fairwater and lets the condensor expand and contract with temperature...sorry its not prettied up much...still experimenting
It works!

Re: Rushforth
Nice Dave, thank you.
I'll think the pipes are about 1 inch?
But the lenght of them?
I like the streamline before the condenser, good idea.

Re: Rushforth
They are actually 3/4 ID tubing which makes the OD about 7/8".
Take the Outside diameter in feet (0.875/12) x 3.1415 x L = 2 (IHP) for my engine.
I have some condenser area ( 1 square foot) in the feedwater heater also, so I think I am putting out a bit over 2 IHP....
L = 8.73 feet approximately which is what it is....for your condenser, it will need to be longer or larger in diameter or both.
so
OD (feet) x 3.14159 x L (feet) = BHP ( I think you said yours was 3)
Using 7/8" OD tubing
(.875/12) x 3.14159 x L = 3
L = 3 /((.875/12) x 3.14159) = 13.096 feet (OK call it 13 and skip the extra 1/8":D)
Dave
PS Oh and Silver solder only!.....if you break you condenser, your in for a fun time keeping afloat....so don't go cheap here...

Re: Rushforth
Thank you Dave,
Its all clear to me now, you are a perfect teacher.
Yes, when I bought the engine in England the seller sad it was about 5 hp. But I think thats a little bit to high. 3 hp is closer I'll think.
I solder everything whit silver, everyting fits than and its fun to do.
Keeping her a float would be nice to start whit I think, thats difficuld enough.
Thanks for the instructions Dave,
Piet

Re: Rushforth
Your welcome Piet...any time.
If you can determine the cut-off of your HP cylinder,and the expected engine speed, I can determine how much steam you will be using. You can usually use 45 pounds /Hp/hour as a good starting point.

Re: Rushforth
Hi Dave
Nice guy you are, now I lost the way again.
The cut-off of the HP? I know the HP. I know the the stroke and the diameter off the cilinder.
But what is the cut-off?
The boiler I have is can give 185-200 pounds steam an our, firering coal. I use parafine.
So I think something as 160-180 p/u by 150psi.
The engine is 1,5X3+3,5.
