Hi,
tnx all together for that welcome :-)
i came from nienburg/weser, between Hannover an Bremen
(most people don't see it while driving through xD)
to my little machine:
cylinder, pistons, crank, valve chest and cover, all rods, croosheads and a lot more parts are made of cast iron - milled out of blocks, nothing was casted (not sure if called right)
piston rings, steam fittings and some visible parts are made of brass
cylinder bushes are gunmetal
base and stands: C45
cylinder plate and round stands, also valve rods: stainless steel
its a double twin :-) with marshal steering, works from 1atm and spend more than 400W at 8atm
lowest speed was about 300rpm
some pics of building:

maybe that i find some more pictures - but not sure.
the build has passed too fast as i could made some pictures :-)
initial stage 24.08.08 - first run 10.09. same year :-)
but within this 3 weeks there were more than 300 hours work
