[TheForge] oxy-propylene, propane tips and air-arc

[Jerry Frost]

You could try stringing a series of shallow ball and 
socket joints made from mild steel, strung on a cable 
and mount it on a heavy duty switchable magnet like you 
have on a MAG-drill. Switch the mag off and it's a limp 
thing, position the business end where you want it and 
switch the magnet on and it stays there.

There's a fellow making human sculptures like this 
though they're all posed on his magnetic mill table.
