Deutsches Museum - Munich
Today we visited the Deutsches Museum in Munich and all I can say is wow, this is exactly what a museum should be. My son and I spent more than six hours wandering around and still only got to see about half of it. Here's a few photos but nothing can do justice to seeing it in person, and this is just a small fraction of the engines, pumps and other machines in the mechanical power section.

1865 160hp Poppet valve steam engine, note random human to indicate scale.

1835 20hp Beam engine.

1863 12hp Double side valve steam engine, I've never seen one of these.
Cheers,
Greg.

Here's some photos of the lineshaft workshop in the machine tools section. Apologies for the picture quality, the lighting in the line shaft workshop was at a level to simulate kero lamps so not the most conducive to taking photos.

Great photos!!!! The design and detail to be pleasing to the eye is so good. In our "do it/want it now" way of doing things seeing machines that are ornate is great
Just do it!
Kind regards Rod

Waldrich Coburg planer, note the two heads allowing two surfaces to be machined simultaneously.
That's about it for now, posting photos using an iPad is a pain in the bum. Apologies for some of the photos appearing to be cropped, I'm not that bad of a photographer, it's just how they come up when they're rotated on the iPad in order to get them to display correctly.
Cheers,
Greg.

Hi Greg
many many thanks for the pics, loving every one of them.
I'll try and explain the double valve .
The outside valve rod is connected to two adjustable blocks that ride on the outside of the main valve. Hidden from view is an adjusting handle that either brings the two block closer together or further apart This set up is called 'Meyer expansion gear' or a 'Meyer overriding valve'.
A good way to explain this is that in a car you accelerate to get up to speed then back off on the accelerator and cruise at speed with little throttle.
In this type of steam engine once the engine is up to speed using full 'admission' of steam which is about 70% of each stroke you adjust the (hidden) handle and wind the blocks closer together which only allows steam to enter the cylinder for about 30% of its stroke saving steam consumption. Boiler attendants love them.
On some engines the governor controls these blocks. And if you have been to Sovereign Hill you would have seen two engines like this and a third one with a slightly different setup to do the same thing.
I can post some pics if you would like to see the blocks.
I'll also apologise for this post but I can't help myself, probably withdrawals from doing this all day long anymore.

Thanks fellas.
Phil, thanks for the explanation, your info is always valuable. There was a skeletonised model of the Meyer valve which could be operated by hand to show how it worked, I guess I must have seen them before it's just not something that I picked up on until it was highlighted.
Cheers,
Greg.

Better Late Than Not At All
Hello Greg,
Thank you for the wonderful photos. I was there in 2011 and spend the best part of two days in the museum. I did post numerous photos in the general metalwork forum but they have nearly all evaporated. The Maho and transparent Flott were not there at the time of my visit. I wonder what else has changed......
Bob.

G'day Bob,
My son and I were in there for two days and still had to race through a couple of floors.
It's an amazing place all right.
Cheers,
Greg.

G'day there Greg, I too would like to thank you for all those wonderful photos, if ever I get to Germany, I certainly want to go to that museum. I hope that you continue to have a great trip and an eventual safe return. Thanks again for spending your scarce and valuable time to share your experiences with all of us here. Cheers,
Rob.

G'day Rob,
You're most welcome and it was my pleasure. I can highly recommend a visit if you ever find yourself in Munich. These were posted when we were over there last year but thanks all the same for your well wishes.
Cheers mate,
Greg.
