Brass joint

 You got balls? 

My friend asked me when we went to Caribou hunting, there were dangerous snow trails by the beach, and somebody needed to pass through there. I said 

“Yeah, I got but small…”

Anyway, I got small balls from China. 

Will use 6mm balls for joints for the regular armature and 8mm balls for the bigger armature. 

But they only sell joint plates for 6mm balls, that is why will make a joint plate for 8mm balls somehow.

I cut a 2mm thick brass plate and drilled halls without jig. Every plate needs holes same place, but I can't make holes same place. Can't fit balls, joint not working. 

Then I plan a design jig for the joint.  I draw on paper, it looks easy to make, but it is small and hard to make with metals. 

Drilling holes, cutting, and filing brass plates all evening. A few evenings later, finally, I finished a jig.



Jig for ball joint

I can make 6mm and 8mm, one ball two ball joints. 

6mm, 8mm ball joint, and jig.

Molding

By
Hello everyone. It's been quite a while since my last post. So sorry. For the past few months, I've been having trouble creating a "mold" for a character's face. In the end, it turned out as shown in the image, but I'm sure we'll encounter some difficulties as we continue working on it. However, I think that even this is part of the charm of stop-motion animation, right? 😁

Scale Model and Silicone Mold ver.2

By
Our test shoot went reasonably well, so we've been hard at work creating assets ever since. Recently, we welcomed a graduate of Tokyo University of the Arts as a member. It's very encouraging. However, since we are still a small team, it is inevitable that each person will have to handle multiple tasks at once. Currently I am making two scale models of kayaks, one for normal shooting and one for "distant view". Additionally, I am reworking the default mold for the main character. It is possible to mass-produce faces using the molds I made previously, but I didn't like them because they looked too distorted. This remake was a good experience for me in terms of getting used to working with silicone.  As for our future plans, once the main character is complete, I would like to do some more test shooting. I'm sure we'll be able to see some expressions there. I'm really looking forward to it. You may think that the production process is slow. But I'm n...

Bending

By
  Hi there, I am still working on the scale model Qajaq. Even though it is a scale model, the process is nearly identical to the full-scale Qajaq. Ribs and cockpit hoops are also formed by bending the materials. I boiled the rib material and bent it using a jig to scale. Of course, I made this jig as well. The fact that we have to make the props for the props ourselves is perhaps a big difference from CG animation. Yes, this is truly one of the best parts of making a Stop-motion animation for us. It's not hard to bend these thin pieces of wood, but the problem is that once bent it's difficult to install them onto the gunwales. My fingers seem too thick to move freely between the gunwales. Oh, just to be safe, it is better to chamfer the rib material. The cockpit hoop material is first boiled lightly, then wrapped around the "form". It is fixed with a stapler. Then boiled again and is drying now.  You may be thinking, "This cockpit hoop is too big, isn't it?...
