[MOC] Porsche Boxster/Cayman
Thirdwigg posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'm sure like many other builders, I have been enamored with the 15 wide car scale ever since the 42098 Car Transporter came out. I have enjoyed all sorts of little cars by so many different designers, and have made a couple of them myself. The little axle base engines have been fun to see develop in many different applications, and make a great sound. Plus, being not too part intensive makes for a lot of accessible builds. As a longtime Porsche fan, I have longed to MOC some of their cars, but I have not been able to come up with a decent Boxer engine, which is key. @steph77 came up with a nice little design with a 911 designed a while ago, but I wanted another idea. I first came up with a little idea, but it did not save any space from the standard piston parts. And, visually, my eyes were drawn to the crankshaft and mounting, and not to the pistons. But I liked the rotating connectors. So after a little more tinkering, I came up with this: There are three cams on the crankshaft, and an upper pivot for each "piston." Each piston is mounted on the connectors, and swings in and out, as the crankshaft rotates. It's not perfect, but the size is right, and it makes a nice little racket while moving. Naturally, I needed to build a car for the motor. A 911 will happen at sometime, but there are not many Boxsters/Caymans out there, and I have a deep love for both. Also, after building the E30 series last year, I thought another car group would be fun. I stared with a simple mockup, with the engine in place and some other functions, and I like what I had enough to keep going. Steering with HOG is in, as is the rear differential. Then I realized I would need to have a convertible top. This may have been a step too far. I worked on a number of mechanisms using the draft table below. I think this is draft 3 of 8. The top is still not finalized, and might not be for a while. But I have enough of the placement of engine, axles, bodywork, to know the constraints I have for the top. I'll get there, but it may take some time. The idea is to have the HOG on the armrest when the top is down, and manually extended by an axle through the roof when it is up. I tend to build a Studio file when everything is done, but this project is requiring a little more design/redesign, so I have a couple of drafts in Studio now. And this is where the "final" draft currently stands. I'm not sure about the roll bars right now. I love the look, but the part is a little rare. We'll see where this goes. Not everything is working great yet, so if I can't figure it out, maybe I'll just end with only a completed Cayman. I welcome your questions, comments, and insults. -
Hello there, here is my latest moc, a more than 100 studs long spaceship, the cayman class battlecruiser. Cayman class name is due to his shape, looking like a cyaman's head. By visiting the flickr gallery, you'll be able to see WIP pictures of this moc, showing technics used to build it.
