  1. Introduction Hello, I present to you, my new, first fully-finished MOC and entry to TC10: The 'pneumatic press'! About I wanted to participate in the contest, and it should not be a problem for me since i have 42043 with all it's pneumatics. I didn't want however to create another vehicle. I really like the Hydraulic press channel so i decided to make a hydraulic press, well a pneumatic press to be precise. So here it is. I am creating the discussion topic after the build but that is perfectly fine because i have progress pictures which i will show you. If you have suggestions for mods etc. you are free to suggest. There are for sure a few flaws which can be made better. so it has a few functions - You can move the platform to position your part (2 yellow knob gears). You can move it for-/backwards and sideways. - The yellow blast shield can be opened with a small pneumatic cilinder. - There is a big cilinder for pressing. All controls can be found at the front. For safety there is a blast shield, just like in real presses. Building progress I realised that i had to make progress pictures when i was here: I had then made the positioning and i added a pneumatic pump. I made the platform such that it can handle a lot of weight, well it remains ABS plastic but i made sure to build it such that it doesnt fall apart when there's weight on the platform. As said, you can move the white platform sideways and for/backwards. This is done with gear racks. one knob gear is moving with the platform (in one direction). I can make something so that it doesnt move but that would make my MOC even uglier and i don't think it is a real problem. My plan was first to put the pump in the top, so that the tubes dont have to go up the pump. Later, i realised that you need a control panel and that the switches have to be at the bottom. So i added the pneumatic pump at the bottom. I didn't like an exposed pump so i used a beam and a lever mechanism which you will see in a video further down, OR in the final entry video. My first function is the blast shield. It works pretty nice and the blast shield doesnt look that bad. What i don't like is that the supports stick out. The blast shield cant clap up 90 degrees, but i don't think that is needed and it would make it a lot more complicated. then i built the cilinder for pressing. It only has one attachment point so i had to make a frame such that it can't swing. the 4l axles, next to the pins, will later be replaced with 7l axles but you will see later on. This will be attached to the frame This cilinder also has to be connected to the switches and when all the tubing is done, the underside looks like this you can actually see that i had too little space for all the tubes so i gave him 4 feet (the LBG rims). then i need to do panels to work it off. You can see that i used some frames and beams to make the top part stiffer. between the black panels, come the grey panels which can fold out On top of that goes a cover which wont be attached with pins. This is so you can easliy see through and repair/change something. Now it is done, finished. here is one more picture The way the black panels are attached is really ugly. Then i built in in LDD, this way i can see exactly how it is made and where it is the weakest. file can be found at the bottom. While building i changed the model a bit. I replaced 2l pins with 3l pins. Red pins with axle connectors for regular pins, and added extra pins for more firmness. i also changed the way the black pannels are attached and i added a some beams. On the cover i added 2 red 5l beams so you can pick it up more easily. the final version is the one, made in LDD. Of course there are no pneumatics but it is pretty clear where they have to come. It is very good visible on the pictures. I couldnt find a few parts in LDD so i used something else. Updates/Changes Let me know what you think. What are good and what are bad things about it. Feel free to suggest changes because a MOC is never perfect. I haven't done measurements like part count weight, volume etc. but if you want to i can do that. does anybody know when i can enter my moc in the entry topic? Upgrade 1: post #13 I am not gonne upgrade the lxf file, maybe later. Here is the lxf file: pneumapress.lxf
  2. Hello everyone, this is my first entry on eurobricks, I hope you like it. I decided to enter it as I was already working on it when I discovered the contest. As it's an ongoing project I will continue to upload pictures as I take them Important note- Some of the older pictures may show power functions, as I was experimenting with using an Sbrick to control the phneumatics. To be able to enter this model, I have replaced them with a manual system. Here is the link to the photos: Having been inspired by the Lego models at the 2014 Brickfest convention, I decided to create a display spaceship. So far, I've done the central weapon ring which has 72 spring loaded launchers attatched to tracks to rotate them round into launch position, all of the frame sections and I am currently putting the exterior hull and detailing on. Each section features openable spring loaded hull allowing various rooms to be slotted in (bridge, hangar, engineering, airlock...ect - I've also decides to have some sci/fi jokes; redshirt being attacked by an alien, stormtroopers & vader boarding through the airlock, the TARDIS landed in the cargo bay, Viewport room with a double-decker couch). It will eventually be white all over with dark red highlights (Inspired by the S.O.E. Ships from EVE Online). This is the first SHIP (Super Huge Investment In Parts - anything 100+ studs long) I've ever made and is 157 studs long, 61 studs wide and 47 studs tall testing the shuttle bay doors (with sound effects) - The Phneumatics use came around when I started to consider how a real life spaceship would apply reverse thrust to slow/stop/back up. Most ships in books/movies will either: 1- Flip the entire craft 180' so the main engines can then be used to change velocity eg - the reavers from Firefly 2- They have dedicated engines pointing in the opposite direction to the main ones to slow down. - the SSV NORMANDY from Mass Effect After some thought, I was inspired by the impeller nozzels on the British channel ferries and the engines on General Grievous's command ship from Star Wars 3 (watch the movie to see how the regain altitude the first time it nearly crashes). The same principle is also used on jet airliners to help slow down. The ferry impeller nozzels also inspired me to mount the engines on gimbals to allow vectored thrust, improving the ships manoverability. The original prototype engine gimbal test - the developed engine, testing the nozzles - This was the original pneumatics control system, motors controlled by Sbrick powering small actuators attatched to the valves. However it was extremly cumbersome and difficult to work, Overall I considered it a useful failure to learn from and replaced it with a manual joystick - Engines fully constructed and mounted, using the manual joystick to control them - and another view - This project has been taking me longer than expected, as I've had to buy a lot of parts a few bits at a time. If you put all the construction time together then its taken around 1.5 months of a couple hours a day Future development: Overall I'm satisified with how the pneumatics turned out, however the engine baffles have a lot of friction and tend to stick (as seen in the video). So I'll be modifying them to prevent that happening. I'll also need to check the hoses as some of them are old and there's a leak somwhere I'm also investigating the viability of having a smoke machine piped into the engine with some flexi-hoze, thankfully the gimball have a nice hole though them so minimal modding will be needed. Finally, I'll need to build a proper stand to support it as the slapped together cradle of large tyres to hold it is unsuitable for long term use and it also blocks the lower hull opening.
