Ideas for MOCs

[efferman]

there are many sequential gearboxes build complete with lego. there is no need for specialiced parts

can you build a fully mechanical sequential gearbox? i'm thinking of making one, but still pondering how to do the sequential part mechanically.

Piterx has a couple of designs, both partially described in the forums here. The first was for his Lancia Fulvia; the second was for his Pajero Pinin. I can think of at least one other approach, but can't find the link to it now; basically the designer used the classic 4-speed Lego gearbox and coupled the tops of the gear selectors with a 6571: . He then used a series of cranks to activate the selectors in sequence; the 6571 ensured that when one selector was thrown, the other one would return to neutral. I realize that's not the clearest explanation but hopefully it gives you some idea.

hi, i think maybe this crane would be very nice:

and i wanted to know if someone can make some custom pieces like the pieces in this model for a tatra transmission:

the blue piece would work as a deifferential and the red and green gears would be on each side and would slide in the blue pin, but would move the wheels axles, i hope you can understand what im thinking, and good luck if you want to make that crane ;).

I would love to build one of these:

Four wheel drive, steering, rotating base, articulated boom with LA's or pneumatics... Could be fun.

What about screw vehicle?

Do it!

I am wanting to build one of the rather unusual Mecalac wheeled, articulated excavators, but I need to "finish up" with all my existing MOCs (video, LDraw etc) before parting them out for new projects

I am currently trying to build a working model of a junttan pm 26 piling rig with power functions an pneumatics.

(Waiting for the new cylinders).

A screw vehicle was already done in Lego by vmln8r

what about a Menzi Muck

How about a "folding log trailer"??

You mean something like this:

In germany we call this " eierlegende wollmilchsau", in english maybe cant fly and swim, but can do everything else

This is the best real size RC toy ever.  Quite a challange in Lego indeed.

That is a pretty nice machine, they took functionality and versatility to a very high level, the feature that i like the most is that multi functional arm, is a very nice idea, is a pretty cool thing, i am agreed with Attika, this might be a really challenging model, but i think it would be worth trying to make it.
