Engines > Restoration of Model Engines

First one, then two cylinders.

<< < (2/4) > >>

Michael S.:
The new pistons were made of aluminum. They also became much longer than the original piston. The stroke of the machine is not very large and with the original piston there would be a lot of dead space above and below the piston. It's not supposed to be like that.
I never made piston rings at that time. Rings were cut from a piece of cast iron. Filed a notch with the file. And separated with a hammer. Heated with a spacer and with an indirect flame from the gas burner. They were under tension and could slip onto the piston.

Zephyrin:
very nice rebuilding work, which promises a nice model.
I have often heard that aluminum is not suitable for steam engines, because of corrosion, but I don't know if this is true.

Roger B:
A nice job on the piston rings  :ThumbsUp:  :ThumbsUp:  I usually split mine with a pair of side cutters.

Michael S.:
I found the original Dampf box to be too small and made two new ones. The slide valve was also created anew as a result. On the cover of the first cylinder is the place where the machine was found and the approximate year of manufacture of the steam engine. At least that's what the machines might have looked like at the time.
The cover of the new cylinder bears my name and the place and year of the restoration.
The flywheel was too small and I had a bigger one lying around.
The crankshaft now has bronze bearing shells.

Kim:
Nice work on this restoration, Michael.  I'm enjoying seeing what you did for the engine.  It looks great!  Can't wait to see the next episode!  :popcorn:
