Chris, nice that you own the book too.I've had the book on my bedside table for a week now. I'll start reading tomorrow.You are right the machine has the Stevenson controls. It is a two-cylinder low-pressure steam engine with injection condensation. Then there's the Penn backdrop. It should be complicated to use. Each cylinder can be controlled individually with a lever system, which is practiced when starting and then the levers are hung in the automatic.There are different designs of the oscillating machines on the ships.I'll do some research.Michael
That's a great idea with the wing screw! I'm really curious how the handles are made.Grinding a steel for the lathe in the profile of the handles would also be an option. I used to do this for profiling the ends of masts for railings. But it was just a kind of ball.Michael
Hello Chris,I looked again for information on the oscillating steam engine in my books. There are few details about it. Even in the German steam engine Bible >> The development and history of the steam engine << from 1908 there is only one picture.I think the control is complicated and therefore only simplified in the model construction book. A member of the German steam model forum built the machine with two eccentrics for forward and reverse driving and also changed the cylinders a bit.Michael
I see what it's supposed to be. The workshop elves will soon have a nice new toy. They will argue who is allowed to steer!Michael
It's not so much the scaling that makes it hard to see... It's that pile of strategically placed swarf behind the part that makes it hard to see the transitions. No doubt it was put there by the shop gnomes in retaliation for chasing their goat away from the rest of his lunch.
