Friends, Welcome to my building arena!

So I’ve been doing a little building this week, and have come up with a few
ideas.
I figured quite a few people would be using those exoforce/knight’s kingdom
joints, and I wanted to do something a little more challenging:
I’ve wanted to make a worm gear frame for some time, so I have been playing
around with various gear combos, trying to make them small but strong. As they
are now, they’re pretty generic, and can either be used in a quadraped frame or
a biped frame.
One nice thing to come out of this project is that I found a nice way to
eliminate the slop in worm gears:
The concept is similar to a techique described by Brian Cooper in his teknomeka
instructions, but this uses different parts, and is a little more compact (I
think).
Unfortunately, I’m running short on parts and time, and next Friday I have to
leave town for a while on
business, so
whatever I don’t finish by then won’t get done. But I’ll see what I can do!
Later,
Chris

That looks awesome Chris.
Recently, I’ve been looking over your
BS joint tech folder for
ideas. You’re the only builder I know who has dedicated himself to creating
compact geared joints. Hopefully, one day I will incorporate some of your ideas
into my mecha!
Can’t wait to see what you come up with next!

Thanks! I’ve always suspected that the main .mecha worm gear builders were
exploiting the gears to create the largest mecha the gears could support. After
playing with a teknomeka frame, I discovered that there is a huge amount of
articulation that is never seen once the armor is added. A smaller, but rigid
frame may support a skin and still be super-posable. I guess I’ll find out soon
enough...

Oh, I thought about doing a gear driven Mecha but then I realized that I
only had a month to complete the project. Awesome start. Good luck!

I too am working on another wormgear driven Mecha project and have loved
borrowing ideas from your folder. Thanks.

Thanks for sharing. Those gears are so awesome.
Hope you find the time to finish!

That new anti slop technique is great! Nice and compact. I didn’t notice those
knobby things weren’t an “even” height. Technic has inexplicable oddities. (I’d
still like to know why the worm gears are too short in the first place. It’s a
subtle torment.)

You got me thinking a lot about anti slop techniques after checking out your
ankle joint on Teknomeka. I used to just chop up technic corrugated tubing to
eliminate slop in worm gears...but Sophie would call that cheating...so I’ve
decided to take the “pure” route...
We complain about the slop from worm gears being too short, but there’s also the
axle flexibility and the lack of a perfect fit between the 8 tooth gears and the
worms...there are all sorts of “subtle torments” in technic...

Some more progress pics (after moderation):
frame 1
frame 2
The black frame was hijacked for a future bipedal project, so I built this frame
after an order of 20 worm gears came in from Pitsco. I’ve used 18 in this model
so far. The joints aren’t really realistic for a quadraped, but they serve
their purpose.
The geared turntable should provide clearer views for those who were
dissatisfied with previous pics of the top of the turntable.
I am not sure what the final form of this mecha will be, but it will be a less
literal interpretation of the source picture than, say, Brian Cooper’s phase one
model. I am sure there will be at least some exposed gears. I like the exposed
technic look - gears look like mechanical muscle tone to me...lots of detail to
see. Besides, this project has been an excuse to experiment with new worm gear
techniques...it would be a shame to hide them all...

Great articulation. Everything is wormed. It should be able to do some unusual
poses that not even the one in the example picture could do, since its legs look
like they just have the equivalent of a ball joint at the hip.
I like how you did the knee, joining the lower leg to the worm frame directly.
I’ve never tried it that way.
The rotation joint above the knee might be a weak point since it isn’t locked
together vertically. I can see how it might pull apart.
I’m not sure what will happen if you double or triple the weight. Better be
careful to keep it light.
Remember that the heels take some of the load off, so you might want to add them
before you decide that some particular joint is too weak.
