I don’t see any doubles or stiffening a la Snead.
|
No offense, but I don’t use handicaps. You ougta know that.
No insult intended towards our good friend.
|
Ouch!
Actually, I’ve designed most of my recent frames and mecha to use only
readily available lego parts, with no stiffening or gluing required.
|
It was Bryce’s fault! I’m telling you! lol, just kidding.
I think we remebered back to an early model that used some stiffening
techniques. I absouletly know that your newer and later models do not use such
techniques. Your still the Mac Daddy.

The double ball joints create the kind of stiffness your talking about.
Plus the shoulders use glued ball joints from Bionicle watches.
That connection point’s only purpose is to swing the upper arm and pivot it
front and back slightly. The dual ball joints adjacent to the shoulders,
work the splay function and provide a sturdy base for the arm structure. The
dual ball joints located throughout the frame work great, very stiff, very
strong.
The hips use the single piece dual ball joint part I pointed out.
That eliminates any seperation in the hips.
The 4 single ball joints in the shoulders and hips work in concert with each
other. Along with the arms and ankles, the spine also adds a dynamic to
where the stresses are channeled.
Without trying to sound over technical, the thing is sturdy, flexible and
hold’s it’s pose. Part of the beauty of scale and inter-relation between the
limbs and joints.
Sorry, I guess I’m bound to sound Technical, sorry to bust your rusty balls.
hahahahahaa.

I understand some of what you’re talking about - when you restrict a ball
joint to one axis of rotation, it is much stiffer than if it is allowed to
rotate freely in any axis. Think of it as a technic friction pin with three
times the contacting surface area.
|
Ahh interesting way to put it. I didn’t think of it like that. Thanks!
| |
Actually, over time, the restricted ball joint will become extremely stiff
and even binds due to the buildup of plastic dust. The best way to overcome
this is to switch ball joints from time to time.
|
Right. Very true.
| |
As for the joints which only use one ball joint, that will become weak over
time. There’s no way around it...even if it is moved only a little in more
than one axis of rotation...
|
I think so too. Fortunately, the frame only has 4 of these single connections
(not including the head/neck) so the dual balls in the rest of the frame should
absorb the flex. Plus if you move the joints around a lot, they will loosen, so
perhaps just admire it? Constant play and movement will surely result in less
holding power. Or you could just use sound effects and make up for the movement.
lol.
I need an auto ZRX1 testing machine.

we are leaning towards recomending gluing them.
|
Booo! No gluing! Get the Bionicle watch part. If you glue lego together,
you’ll always regret it; you’ll find yourself staring at that one part that
you never thought you would need for anything else that is permanently welded
to another lego with M.E.K. cement. Plus, the M.E.K. glue doesn’t work well
on the technic ball joints - the peg just comes right out.
|
I hear ya. Thing is the Watches sold for $19.99 USD and the model uses two of
them. Making the custom set expensive if sought out. If the ball joints in the
shoulders are glued and sold as a set, it is our hope the buyer will keep it
together, thus not regretting the two glued parts. We were thinking about
including a small dab of modeling glue to let the buyer decide.

Blush, sorry Chris, you rock, what were some of those Snead Techniques and >
how we used to say stuff like, Snead my joints baby...! lol
| |
Plus this has made me actually start building the frame I’ve been thinking
of since LAST time Snead was actually down here...what 9 months ago?
|
Snead! I come for you!
|
I’ll be in both L.A. and N.Y. very soon. I’m in Texas now... I come for both
of you!
|
Ha ha! You better hit a brother up! I’m right on the NY/NJ waterfront.
We have lot’s to catch up on, plus I have got to show you some mechanical stuff
in person AND the chest of the Skrylitch.

Thanks Bryce, and congrats again on your win of the BBC 25 for the Rack.
Really very cool and a way out concept, bravo!
e
|
Eric, this is a very new and interesting project for you. I like that you
are trying a different type of building which will untimately be fused into
your present style. And those scorpion hands rock!
|
Hahahahahhaaaa, thanks, wahat a pain to build small hands and either not copy or
build out scale. Thanks, you gotta “hand” it to Master Gla, (pun intended).
| |
My hope is that this will someday lead to a worm gear frame from you...that
would be so cool!
|
I was talking about that with my two project buddies.
I already did. It’s called the
Macro Bot.
Peace, thanks for chimming in.
e
P.S. oh oh, I ment to give you props; during this project, I always felt like we
were following in your footsteps. Your frame/armature development was an
inspiration and much props are due to you for your ideas and the way you worked
with scale. Thank you.
Frame by Chris Snead
Many thanks and inspiration to Master Gla for his Armature Frame as well.
Thanks to Master Gla for providing the intial inspriation to MC7.
