[HELP] Heavy Load Bearing Joint (Multi-Axis)

[mrfang2]

okay, ive been working on building a full sized version of the construct-o-mech from the lego movie. not acurate, but the right size atleast. anyway, im having a ton of trouble coming up with the hip joint on the model. what i need is something like this:

im currently using these as the main actual joint type in the design, as from what ive found its the most sturdy joint type lego has.

but those leave an odd amount of length between the axis for the outward and forward/backward movement, and make it impossible to build the hip around.

in short, anyone have any ideas for a hip joint that can hold up a lot of weight? im kinda new at technic building, so nothing ive come up with has worked.

It's not (really ) Technic, but maybe this could help you : Witch Doctor's hips are really strong, it might be the solution you need. You can see an alternative (far right) on Mike Nieves' flickr gallery.

thanks, but ive actually tested that one, didnt work, like, at all. unfortunately. thing flopped down and shattered, and that one was only half the size it is now.

i realize i shouldve given a reference for what was being held up... its this so far, plus 2 large cranes on the back, and fairly hefty arms as well.

Is that a gbc module?

Have you seen the LEGO Movie? If not I it is Emmet's mech from the end

I doubt that any kind of ball-joint or other "poseable" connection will hold up against the size and weight you're planning to put on. (But then I'm not much into poseable figures, so I might be wrong)

For something this big, I'd rather try and go for a solution with self-locking movement (like worm screw and gear) that will be posed by turning a little knob or something similar.

Oh, yeah, I wasn't expecting it to be that big.

or do you want a connection between legs and the torso?

you could go to the extremes of using mini linear actuators and this part http://www.bricklink.com/catalogItem.asp?P=92911 and this to connect with it http://www.bricklink.com/catalogItem.asp?P=92910

well, i had to add 2 of the axel olding piston bits to the sides to give it more friction, but the thing actually works perfectly! what im looking for is a compact way to connect the hip and the waist together. btw, did i ever thank you for that waist design? because you probably saved me like a month of work designing that thing its amazing!

[mrfang2]

current lower body, using the above mentioned torso joint, with slight mods, and the hip/legs ive gotten working. i need to double up jointing on the forward/back joint in the shoulder, and the ankles still need more work, but this comes the closest of all my attempts so far to actually supporting the body. you guys have any sugestions for improvements before i start armoring it up? im thinking axel piston bits at the sides of the knees and ankle to stabilize those more, but no clue how much that would help.
