there is a big green box sitting behind the steam engine, bet thats where the diesel is sitting. Been studying the engine in the movie, yes im pretty sure its a just a prop :(. But the real question is, if your building the amazon queens engine, do you build the scissions or the prop engine in...

Thats what I have been thinking, large wood fueled boiler, low pressure, big cylinder. Many, many mysteries about the queen. Agreed, pretty heavy construction for a marine engine.. Wheres the flywheel?? If we could only find some information on the engine, ive looked and looked, but cant...

This is where you are confusing me, The stills I posted at the beginning of the thread are screen shots I took with my cell phone from the movie. That may explain the color differences?? Ill watch the movie "again LOL" and try and get you some more if you want.

Gordon, I posted that link in post #8. It is a computer simulation of what the queen looks like and not a screen shot of the movie. OOPS sorry, they are screen shots...

ok, time to sit down and watch the movie 75 times!! I bet I could get enough still shots from it to design a very good likeness, If I only had the time...

Looks like something I would have done.....

Im pretty sure the engine in the movie is real. one point in the movie when the (rubber hose) steam line was shot off they show the engine starting back up. There was no steam involved but if you look at the position of the stepheson link it is set dead center so there is no motion of the slide...

stuart #1 doesnt look like this at all. this engine has 2 support columss and a square backed crosshead guide. Im pretty convinced that it is a real steam engine in the movie and not some doctered up diesel. Looking at the movie and the size of the cylinder and large vertical boiler I would...

. Im not so sure, looks pretty authentic, but the exhaust loos kind small. Whats on top of the steam chest? lubricator??

Huston we have a problem!! Isnt the mb22 a 2cylinder?? here is the rivier queens engine from the movie. clearly a single cylinder of large bore.

aaww man why couldnt it be closer to home....:(

Well now im back to trying to figure out what is that on the OD of the casting...Grrrr thanks for that!! if you have a good gear reduction drill one of those plaster mixers works out ok for mulling small batches of petrobond.

And didnt bother to say hello?? Shame on you! yes your gating and head pressure are probably your two biggest problems. Did you riddle in your first bit of sand? If you didnt that would explan the surface finish on the OD of the parts (I was thinking it was some sort of dross thats why I...

Very odd surface finish on the OD of the castings. Does it get worse the farter it gets from the ingate?

And thats why I keep playing with the home 3d printers and investment casting. Im learning more and more what works and what doesnt, as well as different approaches and processes to get the results im looking for...

Bits and blobs of scrap bronze?? Where did this bronze come from? Its looking more to me like you may have red brass??? Or maybe created a new alloy? Sure is alot of flame jumping out of the furnace, maybe not combusting in the furnace? Ugg, I see lots of issues, hard to pin point anything...

Look on the johntom site. Google free steam engine plans..

nice work on the block pattern. It looks great!!

you know you could all ways drill a hole thru the bad area, then turn a plug on a slite taper, drive it home, then machine it.
