A little "off topic" because of the engine size, but still relevant to the topic. The engine of my original vintage tractor is a DEUTZ Diesel (type MAH-914) with a displacement of 1.100 cc and 12 hp. Data sheet values: Compression ratio 1:20 Compression value 26 kg/cm2 (~25.5 bar) Release...

You have to search for “Lanz Bulldog” or “Heinrich Lanz” on YouTube. (Heinrich Lanz was the company founder.) "Markus Lanz" is a talk master in Germany with a political discussion group on current political topics. (I don't watch his show, it doesn't seem neutrally moderated to me.) Google...

Last Sunday, on May 5th, 2024, we had an event at my vintage tractor club with an open workshop and the special topic of two-stroke diesel hot bulb stationary engines and Lanz Bulldog. Here is a link to a video with a few highlights. It rained briefly a few times, but mostly the weather was...

May 1st is a public holiday in Germany. There is always a vintage car and steam engine festival taking place at a nearby sports airfield. The location is in the south of Germany at the Eisfeld airfield, near the town of Muensingen Dottingen. All kinds of classic cars (cars, motorcycles, trucks...

Here just as an example, the carburetor from the 103 years old Amanco Hired Man (hit & miss engine). Very simple, a check valve in the fuel line at the inlet. Just a nozzle needle and the air intake housing. Dieter

I don't just use ordinary plain paper for the seals. It is the sealing material from the manufacturer ELRING with the brand name "ABIL". I think the material should be available worldwide. With compressed air you can't see any leaks. When using steam, the steam condenses at the leakage point and...

Hello Timo I'm not sure if it was a question for me or for Jasonb. My intermediate plate is clamped with the steam chest and two paper gasket between. With the exact hole pattern of the control slots at the gaskets. Dieter

I once had to increase the distance from the slide box to the cylinder a little. I made an intermediate plate for this purpose. This is exactly how the control slots can be repositioned. Simply make an intermediate plate with the correct spacing of the slots. You need only one more gasket and...

Yesterday we reopened the workshop in our vintage tractor club for the 2024 season. We carried out a technical check on some engines. Because the weather was without rain, we ran two engines for testing. Of course my new acquisition, the AMANCO Hired Man and our largest engine, the BEIJERS HP 20...

Hello everyone Here I have a few more pictures of the plain bearings on the crankshaft. The engine is a two-stroke engine that sucks in fuel through the crankshaft. The windows in the crankshaft determine the time at which fuel is sucked in. Dieter

Hi Pat In order to be able to produce and assemble the crankshaft in a straight line, I used an auxiliary mandrel. (In German: "Hilfsdorn", google translater found only the words "auxiliary mandrel" for it.) It is a steel bolt that has been precisely ground for a slight tight fit. I didn't...

Hi Pat It takes a little time for me, make a rough sketch and find the right word in english for the explanation. But first of all, back then I had a fully equipped tool shop with a cylindrical grinding machine for inside and outside diameter. Dieter

Hello Pat In the early 1980s I built a 2-cylinder 2-stroke boxer engine based on the piston and liner of an ENYA 19 glow-ignition engine. The crankshaft is case hardened and ground inside and out. The crank pins are also case-hardened, ground and pressed in. The crankshaft was then pinned to...

Regardless of the examples given. When I recognize that someone is resistant to advice, the following applies to me. Talking is silver, silence is golden. Otherwise you have to waste your time on the topic. Maybe things will change later because of physical fitness, when your own radius of...

There is a Live stream: Ohio, Armstrong Museum. https://www.youtube.com/embed/IXkaBdVQfFA?wmode=opaque&start=0 The next total solar eclipse in Germany will not take place until 2081. That's well outside of my remaining time.
