Kicking up some dust
Kicking up some dust or Look Ma, no arms!
Well here at last are the innards of the character Jack Sawyer whose green head you may have seen earlier. Well at least the bottom part of his innards.
The chest/shoulder block has been redesigned, the one shown is not ready for prime time and probably never will be. I am pretty happy with the feet up to the spine. The rest is to follow soon, been on Hiatus too long time to start making chips again.

Woo. Thars a purty incredible design thar, Mark! I never did see on elike that a for. It looks highly animatable, which is a really really good thing.
(yay, action)
Hey, it's Moon Guy! Damn, that's some nice work Mark! How tall does this fella stand? Thanks for giving us an inside glimpse into Fullerton Studio! Now make some more chips! Or we'll sit outside your house all nioght every night blasting the CHIPs theme song over and over and over......
Ooooh.... I need details!
It's looking like you're using aluminum for the upper legs and feet? (Or is it stainless steel all around?)
I see a hinge in the toe. A step-block at the ankle (interesting choice). Looks like a stepblock at the knee -- why not a hinge? Some sandwich plates in the spine -- and with countersinking? ...And are those collet joints up at the chest and neck?
What size screw is that in the knees and spine? And what size tap did you use for the toes?
Looks like you gave the spine joints some special treatment... Belt sander? You didn't put them in a lathe to round 'em off, did you?
Nice job chamfering the feet.
Yowza! Looking forward to hearing more about this one!
Yes I hope it will be animatable, so far so good, but no test to date.
It's about 15" tall to the shoulder. Please no CHIPs theme song...Ahhhhhh!
A perfect example of everything that is wrong with TV - CHIPs
good eyes Sven, Yes mostly all 2024 alum, the knee joint is step block but with restricted
movements on some axis, it works similar to a hinge joint, but easier to build.
Sandwich plates on the spine with lathe work done after, just messing around really
trying some different ideas to limit movement and try some other machining ideas.
I am not sure about some of the thread sizes probably an assortment. Forget about the chest block it's a 4 ball sandwich plate that does not work - bad design, bad idea, pretend you never saw it, but no collets.
Lookin' great man, its nice to see you being productive :)
More, more!!!
Thanks for the info Mark!
I'm sure I'll do some more research into this later, but... Why 2024? I could be remembering wrong, but I thought I recalled LIO saying this is the mushiest stuff to work with.
Do you have access to 6061 or 7075 where you're at? Say, where *do* you shop for metal? Online order? Somewhere local?
I also just figured out that the Jeff Taylor in your links bar is the same guy who wrote "Armatures 101." Have you read that? Seeing the aluminum had me figuring you must have been influenced by Brierton's book.
Oh -- and that piece of furniture in the background... Is that what's called a "toolmaker's cabinet"? I just picked up a book called "Model Engineering: A Foundation Course," and noticed something very similar in it.
Questions, questions!
Mark, I'd really like to know more about what you've done here. I'd like to understand better how you made this gorgeous aramture and why you thought to make one type of joint over another. (Hope I didn't walk into that one).
Would it be too horrible to snap some shots while you're working on the next bit? They could be small, bad, flash shots, just something to illustrate how one could possibly do likewise.
If that's too horrible, then I'll be satisfied to just admire what you've done.
Well I don't know what happened to my earlier reply, but here goes again.
Answers, Answers! Sven, the 2024 alloy is pretty hard, that or 7075 would be my first choices for aluminum armatures. The 6061 is probably the most common aluminum you will see, but a poor choice for armatures, it's pretty soft. Reread Tom's armature book, he uses the same for his aluminum armatures.
I get my metal at a couple of local scrap yards or the local metal supply house, I have not tried the online stores yet.
Yes I have the Jeff Taylor book, I don't remember seeing a title? It's pretty good, lots of blueprints and photos of classic armatures as well as Jeff's fine work.
The tool chest in the background is nothing special, it's a Kennedy tool box, get them anywhere.
Shelley, I would be glad to pontificate on the various types of joints...cough, cough
I will snap some photos of the chest block as I remake it and post some of my thoughts on the various armature joints and their use. Thanks for the interest.
yay.

Where did you get that? You misconstrued what I stated. 2024 is the denser harder aluminum. 7075 is also a stronger aluminum than 6061. The 6061 is the most common aluminum around and more easily available to the regular consumer,and also, what you would see stocked maybe at a Homedepot or Lowes. It's good for chest blocks and such and I have used it for larger aluminum swivel & hinges, only because I was too lazy to order the 2024.
My presence is everywhere :o

Hey LIO
Glad you stopped by to clarify the aluminum point.
Sure wish we could post comments on your site - any chance of doing a blog?
Mark
