I’m building a ball-and-joint armature for the detective character (designs here). The build has gone quite smoothly so far, and I’ll be posting more images as things progress. I’m hoping to be almost finished by the end of the week and on to the sculpting/casting phase of the character build. For an explanation of what’s going on, each photo will have a detailed caption included. I didn’t take as many photos as I probably should have for a true documentation, but I’ll post what I do have. Ask questions! I’ll probably answer them.
Once these holes have been drilled you can separate the two plates and finish the top plate. Expand the screw holes (on the top plate only!) to 1/8″.
Then move to the bottom plate and tap the screw holes with the 4-40 tap to give the screws a thread to grip.
Now you can mate the plates together again putting a screw through every hole you drilled and tapped.
Now place this in the vise again with enough sticking out to do some cutting! Hold one end with a helping hands device (not your fingers, it gets hot!) and cut off at the marker lines with a Dremel tool. Make sure you use reinforced cutting wheels. Alternatively you can use a hacksaw, but a Dremel is a bit faster. Carefully shape the ends of the joint you just cut off to a rough curve and then finish the ends using a metal file.
In part 2 I’ll be soldering the brass rod onto the brass beads to make the barbells that get placed in the joints so the armature can start to take shape! I might try to get a few more pictures of the joint shaping process, but it will depend on time. Stay tuned and thanks for stopping!
