APOLOGIES FOR ANY INCONVENIENCE- NORMAL SERVICE NOW RESUMES.
I went back to basics also with the hand, and took it totally apart- I had another set of palm plates built, and they looked to have better registration than the last hand. I took the last hand apart, and checked each finger for wear and tear- I also filed each finger down significantly- they had been a bit horribly blobby with JB weld- I filed them flatter, and repaired where neccessary.
This is the basic jig my Dad was kind enough to knock up in the shed for me- saves a bit of time and effort, for creating palm plates, and the finger plates- we can improve this further yet.
Below you can see the finger joints in their various states, and the raw barbells they were built from- the balls are 3mm diameter, and they are fiddly to cold weld- they also require a specific 'bar' that is smaller than all other body piercing bars- which is a bit of a pain- and a shame you can't vary the length of the bar. Lighter shown for scale.
The hand once assembled again, and all the fingers sorted out - I actually decided to put another bolt into the palm, and it made a big difference to the finger tension reliability.
The entire hand arm once reassembled- once again, I'm much happier with this- my only concern is the extra weight I have added to the arms.
Rig gets his new shoulders put on first- with the new allen key screw fittings...now, where did I put that Allen Key?
The gun arm goes on next.
These will be much better, as long as the weight isn't too much of an issue.
Stick 'em up!
A few more bits to share with you- the 3 various metalwork boxes I keep to hand- there is a lot more metal than this sorted into plastic drawers too- but these bits get used a lot, so they stay near to hand. First box contains all the balls I've got to hand- most of them are body piercing barbells, ranging from 3mm diameter, all the way to 10mm I believe- some brass threaded balls too. All discovered thanks to threads on stopmotionanimation.com
I haven't yet had the chance to braze these balls into place, but when we get into the studio I'm going to look at moving that way- there are various people there in the building with vast experience of all kinds of welding, so that should be easy enough. I bought in bulk from the body piercing suppliers, so consequently I've got loads of them...
