ABSTRACT:
A demountable coil form for fabricating epoxy impregnated superconductive coils having a split ring and a collar clamp secured to the ring on either side of an axially extending opening for adjusting the size of the ring opening. The axially extending opening is widest at its inner diameter and tapers towards the outer diameter of the ring. Cap screws in contact with a wedge and connected to the ring are provided for securing the wedge in the opening in the ring. The wedge has a taper matching the taper of the opening in the ring and is positioned flush with the outer diameter of the ring. Annular side plates are secured to either axial side of the ring, with the side plates extending radially outwardly from the ring. The side plates define slots which create a passageway from the exterior of the side plates to the interior.
