  1. Dear fellow LEGO enthusiasts, I am in dire need of some help from you folks who are definitely more knowledgeable than I. In this case, I am needing help with the replication of the RMS Titanic's Reciprocating Engines and Turbine. I am in the midst at the moment of working on the project below, though I have not updated it in a great while due to university work. See this link here for the project thread. But this is a minifig scale project, with every door, every window accounted for. This means that in regards to the engines, I am also seeking to make them at least somewhat true to scale and able to work as intended. Obviously this is a big job of some top notch Edwardian-era engineering, but I am hoping that there might be some out there not as technically-challenged (pun totally intended) as I am, willing to help me get this part of the project off the ground. Some of the features I I am looking for include a fully air-powered system, where the air supply would come from tanks hidden in the mock-boilers, that are then funneled at somewhat high pressure to the Triple Recip. Engines, which means that the pressure would go down as it goes through each cylinder (HP, IP, then two LPs). The leftover air at a much lower pressure then goes to a junction that can either go to the Parson's Turbine at what was historically 4 psi, or can go directly to the condensers. With the latter I intend just to make the outside of it and hide inside some custom compressors like this. That would then return to the original air supply. With this I am hoping that I will have a self-supplying system with ideally no more than 5% leakage, or enough compressors that leaks are compensated for. WIth the Parson's Turbine, that can be an accurate shell with whatever is needed inside to include a working turbine, and probably with an gearbox and ascending set of gear ratios to give it the necessary torque. These engines and turbine are meant to actually turn the propellers, perhaps even in water! Some other features would include a replica of the Brown-type reversing engine on the side of each of the Recip engines, making it so that the Stevenson-type eccentrics can change the direction of rotation. Considering the scale, the reversing engine doesn't technically have to be much more than a slightly-hidden piston that does the required job, but any more realism doesn't hurt. If something like this is possible, please let me know. I am really wanting to continue with this project, and this is a central part of it. But without the pieces in front of me instead of on a computer screen, what little I know of engineering definitely doesn't help without that tactile interaction. Thanks for your time, and I look forward to your replies! If it is possible, then I can follow up with the intended dimensions. Here are some references for any that wants some: View of turbine and condensers through wall from main engines rotor shaft model of port-side recip. engine overall basic view path of the steam of original, pressurized air for mine
