Hello all,
my name is Lennart and I now got around to sign up here after being a silent reader for several months.
I am a model engineer since 5 years and have startet of with steam engines, stirling engines and after gaining some experience built some two stroke IC engines.
After finishing school I moved to another town to study mechanical engineering, wich I am still doing and coincidentally I've got a model engineering society with an ground Level 5 Inch gauge track nearly infront of my door. After spending my childhood with an Märklin H0 train set I can now combine my interest in railways and the model engineerring just perfectly. I have thought about staring building steam locos on 45mm gauge some years ago but discarded that idea shortly afterwards. It would have gotten just too fiddly for my liking.
Before getting in to too much detail about my current projects, i'd like to show you some of my previously built engines. I'd like just to point out some of them here:
Having built only pretty small engines before (Stuart No.10, Stuart Boiler feed pump and some own designs) , I set off to build something al little bit larger and Chose the James Coombes wich was eventually completed. I prefered to leave pretty much of it unpainted with smooth but not polished surfaces.

After a visit in the mining museum of Saxony (roughly translated) where a large number of old Heinrici stirling engines was displayed at the time I decidet to build a full size replica. I could get some drawings for the basic engine and could take some detailed measurements from another engine. I made the casting Patterns form MDF an a friend of mine cast them in brass afterwards.

The special double acting valveless water pump had to be designed only from some external dimensions. It does not create lots of pressure but enough to keep the water circulating to cool the engine's cylinder.
Now to make a start on 5 Inch gauge I picked something simple. A gemarn prototype of a heavy duty flat wagon, wich was built by numerous modele engineers here before. After about 9 months ist rolled the first meters on its own wheels. With an wooden Boy on top, it will be used as the battery- and driving wagon for the E69 02 wich I am currently building.

Time will tell when I finish the electric locomotive and can approach a steam locomotive. I have chosen a Kennion's Chub to begin with as ist is simple and light but has an appropiate wheel diameter so that ist does not Need to be thrashed to keep up to the speed of the other locos. There will propably a thread about the Chub shortly here, firtzs to discuss some of the design Points wich I'd like to Change before building can begin.
Since english is not my first language, I apologize for any grammar or spelling faults in my posts.
Cheers
Lennart
