The goal is pretty obvious this year, but may be a lot more trouble. I'm getting tired of the clunkly, pivoting haunts I always see every year on the DIY blogs as well (as my own lame attempts) and always marveled at the fluidity of puppets. There is something organic and random about a dangling, controlled structure - I just want to know if you can have that visual impact with the constraints of only using a single motor. Yes I could buy several and have them set for all kinds of whacky phases but I think the single motor limit is what is driving me this year. If all turns out well, I would be more than happy to reuse this as the primary ghoul year after year.
The skeleton and initial string positions
Hows this thing gonna move?
First I want the dude to pan back and forth at least 45 degrees left and right. I'm gonna start with the simple pivot bar with two fishing lines attached to the collar bone thingys.
Gonna skip over CADing and prototyping and just right in with welding up the base stand and motor mount. I think after I have the crossbar rotating the skeleton from side by side, new options for doing the arm, torso bends, and head twists will present themselfs automatically. Fingers crossed.
!!!!!!!!!!!!!!!! Motor Fails after a 15min run !!!!!!!!!!!!!!!!!!
I've been scrambling for a replacement that will not cost $70 like this one, rotate at between 30-100rpm, and be purcahseable locally! The hunt continues.
ELECTRIC CAN OPENER!!!!!!!!!!!
Lets start by removing the chasis. Pretty gross Vasaline goop in here. Careful during the back removal,
sometimes the gears are held in by front and back support posts. Time to bypass that pressure switch...
...just like this.
Unscrew the can-cutting blade/gear from the front simply by taking some Visegrips and firmly unscrewing it off the
threaded post THE SAME DIRECTION as the can opener naturally travels. Totally guessed because the blade should
be a self-tightening deal.
Ugly tack weld. It only has to handle a few foot lbs.
