No I didn't forget about this build, I just haven't had the time to work on it(I'll blame it my terrible time management and recent schedule changes.) Thus that's why it's been more then a month since my last update. But alas, here is a small update!
I started work on getting together more parts for the engine and propeller. I did find a lego piece that's just about perfect for the propeller shaft and I also started work on preparing the pieces for the piston rods. One of these pieces is the plate that goes on top of the boiler,(where the rods stick out of.) For this piece I used the radiator armor piece from my Zvezda M-3 Scout car kit. After preparing the piece, I measured where the six rods will go(making sure they all were evenly spaced apart.) Then I simply drilled out the holes. Note: I still have to make the rods, out of stretched sprue.
I also finished the top of the piston rods where the rod will attach to one side and where the propeller shaft will go through the openings. For this I went back to drilling out some "pancake" cut pieces of sprue. Then I attached a small piece of sprue and sanded it down so the sides were angled. That's how I got the tear-drop shapes of the pieces. Then I simply threw on alot(and I mean alot) of putty to fill in imperfections.
Next work should move to making the piston rods, that way I can get the plate attached to the boiler. Thanks for looking!
