JUST FOR FUN, I THOUGHT I'D CREATE A LITTLE LIGHTNING FOR THE ROBOTS CLAWS.      THE ROBOT'S CLAW LIGHTNING.     WITH INSULATION ADDED I COULD CONCENTRATE THE SPARK INTO A VERY "HOT" ARC.   THIS IS VERY DANGEROUS!!   BUT THE ROBOT DID IT ON THE SHOW, WHY NOT? OH? WAS THAT JUST A SPECIAL EFFECT ON TAPE? I'M NOT SAYING HOW I DID THIS, BUT AT 16,000 VOLTS AND A HEFTY AMOUNT OF CURRENT, PLEASE DON'T TRY THIS AT HOME, IT REALLY CAN KILL YOU! These are resin wrists with rotating centers obtained through the club. They are quite heavy but look nice. Here is the rotating center and claw mounting bracket removed.   Attached to the wrist is a prototype bracket assembly.  It is made from 1/16" thick x 3/4 flat aluminum bar available through a local hardware store.  It needs to be strong enough to support the wrist and claw since it will be attached to the arm mechanism.  It also needs to be narrow enough to fit inside the molded arm bellows and through the 6" torso arm hole when full retracted. Another view of the wrist bracket. Note countersunk mounting screws.   You can see I have placed the wrist on neoprene arm bellows (1st generation from Norm Sockwell, club member).  I found a 6" arm socket hole allows a perfect fit to the Torso for the flange on the arm bellows.  The wrist bracket is fully enclosed within the bellows.   Here are cast aluminum claws in the raw. (1st generation from club member Bill Kendzierski).   They will require sanding with emery paper and finishing or polishing. Go to Collar Stay tuned - More to come PAGE UNDER CONSTRUCTION
