Small update here. This is the last part I'm working on with is the steam engine. The original resin cabin broke when I try to straight it out...that was bad. I needed shot of vodka to cure myself....the good thing is because of the broken cabin I gain good access to the inside. I make the cabin of plastic sheets and totally scratch build interior...so now it was time for another shot of vodka :)
Here how it went:
...and then I make a opening in tender wall to make and insert small doors and coal...etc...
....unfortunately there is to dark inside the cabin to see all the detail.....but small LED inside the cabin with secret switch will solve the problem....
cheers...
