Congratulations. Your building will continue, but it will be different. I echo "MOCing when the baby is sleeping." It works great...When the baby is sleeping. -

[PORSCHE] Porsche 914

Great job. I love the 914, and this is a great recreation. Well done, and we expect to see more.- 10 replies

Thanks for your response. Questions still remain for me, see below: Since each pneumatic cylinder has the option to receive air from two valves (all, individual), the hoses from "door all" needs to be locked out between others cylinders. In the example above, when "door all" valve is closed, and and "door 1" valve is open to "Up," if I understand the routing of "door all" hoses, what keeps air from flowing from "door 1" "Up" hose, back to "door 2" "Up" hose (see green) even though "Door All" is closed. For each pneumatic cylinder you have a T connector to each valve and one cylinder input for air to come from both valve sources (all, individual). Do I correctly understand where the T connectors are?

Interesting pneumatic schematic for the doors. My idea had something similar, but I could not figure out how to have a master valve control the three functions without the three individual functions influencing other individual functions at the same time. For instance: what is keeping "Door 1" movement from influencing "Door 2" when the pneumatic hoses are all connected? If "all doors" valve is closed and "door 1" valve is open, won't surplus air route from door 1 pneumatic back out the green line to doors 2 and 3?

Excellent work. The boom on the crane utilizes some great ideas. Lots of great stuff in a small package. -

Great news. Thanks for posting. I'm always interested in new aircraft. -
[PORSCHE] 714
Thirdwigg replied to Thirdwigg's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Thanks. This car was built rather organically, though assuming a 25 stud wide car. I built the engine, transmission, and suspension units quickly, then tied it all together with a simple chassis. I guessed (which I don't normally do) on the size, particularly the wheelbase (32 studs). Then I build the body around it, while keeping some design theme priorities (long hood, short overhangs, Porsche rear, flat beltline, round headlighs, and thin taillight). Tying all the bodywork together took a lot of time. -

I needed a bunch of those for my T-55. I did not spend that much, but a lot of shops were needed. Excited to see what you have for us. -

OK. It's solely a track car.Now the roll cage makes a little more sense too. -
[PORSCHE] 714
Thirdwigg replied to Thirdwigg's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hmmm. It seems you are right. I've been doing it wrong this whole time. In my effort to get the steering rack in front of the engine, I failed to see how the geometry needs to be changed. Thanks for the catch, I'll change for the next car. -

Great job. The orange a black looks great, and the rear suspension is authentic. -

I'll third. The models are more creative, and forces some good solutions to problems you may no otherwise see in larger creations. -
[PORSCHE] 714
Thirdwigg replied to Thirdwigg's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Maybe this picture will help. The steering rack is mounted 1 stud closer to the centerline of the body, and the A-Arms are mounted 1 stud further away from the centerline of the body. The steering pivots are 17 studs wide, and the steering rack is 15 studs wide. -
[PORSCHE] 714
Thirdwigg replied to Thirdwigg's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Thanks all for your praise. Thanks for your kind words. Thanks. I felt weird about posting a MOC that was build previously, so I figured something new is more in line with my understanding of the contest.I tried a couple of designs for the roof, but rigidity won out. Ugh, curves in LEGO. The beltline of the car is so flat that I felt the flat roof worked well enough. It is hard to see, but the steering link point is one stud inboard of the upper and lower steering pivot point. -
My dream Porsche lives in the spirit of the 914 and the 924: A compact, lightweight, mass-market, rear-wheel-drive sports car. It has a long hood, short overhangs, and a roofline that alludes to Porsches of today and yesterday. Much more at thirdwigg.com, and the full Flickr gallery may be seen here. Features: Boxer 4 Engine with optional Boxer 6 Engine Rear Wheel Drive 6 Speed short throw manual transmission Limited slip differential Front short/long arm wishbone Steering geometry (caster, ackerman) Rear short/long arm suspension Tilt steering wheel Opening doors Opening hood Internal roll cage The two engine options And the Chassis Hope you all enjoy, and good luck to all the contestants.
