Hello everyone After fiddling with my LPEs for some time, I have finally managed what I think is a first: a running engine using the large cylinders from the new V2 pneumatics series. Like many of us, I was very worried once linear actuators appeared that LEGO had given up on the expensive pneumatics. So I was very happy when they released the V2 system with the Mercedes Arocs set. Well some time has gone by and I simply have not had the disposable income to grab the set, so I finally stopped making excuses and just ordered some of the new cylinders off of ebay. After seeing how high the friction was on the cylinder, I immediately set about modifying them. I drilled the opening slightly larger and added a small amount of finer silicon lube. I ended up with a very large inline-4 with twin camshafts. It runs at a very low rpm but with a lot of torque, easily the most powerful LPE among the ones I have built. Here is the video of me modifying the pistons and running the engine. I owe quite a bit to builders like DrDudeNL, LPEPower, NCJanso, and many others! I started out following their instructions and copying their ideas, until with enough time and practice I came up with tricks and a style of my own. I am quite proud to show the first large cylinder LPE (...I think. Let me know if there has been another one forst and I will give credit). Anyways, let me know of you have any ideas or suggestions for improvement! -
https://imgur.com/a/yc7vwrW Hello! Going to start using this thread as documentation of my LPE (Lego Pneumatic Engine) Powered vehicle, mostly for personal use but also for those who are new to LPE’s and can learn from my mistakes. Currently, it’s a combination of these creations: - A modified V4 version of Green Gecko LEGO Technic Creation’s V8 - Eurobrick user Rudivdk’s 5+R Transmission with only minimal modification for compatibility with frame - Sheepo’s Modular Platform System Unibody (C.A.1) and XL 4-Link rear axle (R.ED.1.4) (modified due to either budget or mounting reasons) https://www.sheepo.es/p/mps.html?m=1 Upgrade To-Do List: - Free-wheel Ratchet for Pneumatic Engine output - Braking system - Possibly V6? - Front axle (Sheepo MPS MacPherson) - Central differential for AWD - Electronics to control transmission - High Pressure Air tank for powering LPE - Vehicle Body(ies) (Most likely will be a DeLorean and possibly also an alternative Subaru WRX STi body) Will update as improvements/milestones occur. Feel free to correct anything (I’m new to posting on Eurobricks so I may have made a mistake somewhere), suggest upgrades, and/or ask any questions. My overall goal is to create a decently realistic LEGO vehicle that will function similarly to an actual manual transmission vehicle. I intend to keep modularity as intact as possible, allowing for the whole vehicle to be disassembled into sections. The only real limit of this project is budget but every now and then, I get the extra cash to spend on improving this vehicle. I will be painfully digitally designing the vehicle in LEGO digital designer along the way and hopefully once the project is complete, I’ll have a complete digital copy of the whole vehicle, as well as a physical copy.
