Subject: PUPT: Nude shoulder joints


 Re: Nude shoulder joints
 Here's the way I solved it with marionettes: I sculpted the chest piece 
leaving a flat circle where the shoulder joint will be.  Be sure and not make the 
width between shoulders too wide because the upper arm (shoulder) will add to 
that width.  Incorporate into the upper arm (carved wood or sculpted/cast 
piece) a ball with the same diameter as the flat circle in the chest piece.  
   Cut out the circle to accept the ball to form the joint.  Make a ball and 
socket joint, using a nail as axle through the ball front to back....drill the 
nail hole in the center of the ball. Cut a slot in the ball to allow for 
rotation around the toggle bolt next described.
    Make a "toggle" bolt out of coathanger wire, with the eye small enuf to 
insert into the ball.  The long (normally threaded) part of the "toggle bolt" 
may be inserted into a short dowel, with hold drilled length wise.  At the 
opposite end of the wire toggle bolt, bend the wire back onto itself using washers 
to prevent the toggle bolt wire from coming out of the dowel.  Mount a piece 
of wook inside the chest piece far enough back from the circle to allow the 
ball to rotate about the toggle and about the nail...This will allow 360 degree 
rotation of the upper arm.
   Depending upon your skill, you can make a completely invisable joint 
similar to a dolls..and if you need more help I posted photos of this joint for a 
hip to midrift joint some time ago on my web site:  www.jimgamble.com   
   I am writing this while on tour in Asia...I'm in Bangkok now and do not 
have my digital photos with me...hopefully my stuff on the web will help...Jim
