Hi, how often do you have to refill the lubricator?

Good question. This type of engine has to be greased and
lubricated now and then (five hours). My lubricator has too
large a pin hole so the oil runs out after a few minutes. It
should be designed to put a tiny drop of oil in the steam every
couple of rotations. So right now the engine starts squeaking
after about a half hour.
Olive oil makes a good lubricant, or you can get some steam oil.
Motor oil is a bad choice.

Hi, thanks for info. I like the organic oil approach, I will
have to try it. My band saw blades keep breaking so I am
fabricating a power hacksaw then I can finish the engine. I hope
to be steaming soon. . Thanks again.

I did some experimenting this afternoon. I upped the battery
bank to 36 volts. Now I am getting somewhere!
Fired up and hit a good 41 volts at 5 amps. Interestingly the
engine is much smoother and the hum from the stator is a nice
constant "thrum". Using more steam but about the same amount of
wood.
I'd love someday to make a small power shed with the steam
engine, a wind turbine and a roof of solar panels. It would be
fun to take something like this to a alternative energy show on
a trailer.

Hi, You have the right idea the cost energy is only going to
increase.
Do you still have the MPPT circuit? Steam engines running at a
more constant RPM, that greatly reduces the complexity of the
circuit.

A fun story.
Yesterday, I cleaned up the steam engine and generator more,
fixed some leaks, so now the boiler will hold cold pressure.
Boosted the battery pack to 36 volts. Fixed the cylinder
lubricator with a much smaller pinhole.
So, everything is cool, running nice between 20-60 psi and 1-5
amps at 38-41 volts. When the engine started running faster and
faster, sounding like a Harley. The pressed in alternator shaft
coupler started breaking loose allowing higher revs. Pressure
shot up to 120 psi and then the safety relief blew. At this
point the engine was running well above rated rpm at probably
1000-1200 rpm.
So I grabbed the hose and doused the fire to slow the engine.
Then I tightened the coupler. The fire was so hot that the
engine then kept running with no new firewood.
Morale of the story? If you want to find the weak link you just
have to be patient and it will show itself. The rotor broke
free at about 220 watts.

Hi, did you have chance to measure the peak no load voltage at
the higher RPM?

Well, since the alt wasn't turning at the speed of the engine,
there really was no voltage peak. It was still doing 1 amp 40
volts just with the slip.

Some footage of today's testing. The water sensor id doing
better placed in the water flow. Fixed some leaks at joints,
fixed the lubricator. The 1/4 HP engine is doing its job and
has been a great test bed for proving the automatic controls on
the monotube boiler.
Next up is a top fired monotube being made in Indiana, and the
addition of a 3 HP engine with integrated alternator I
developed.

Tight for the content of these articles is that we want to read
