Jigs for the stator
Stator studs jig (see diagram 24)
The stator needs four 8 mm supporting studs cast into it. These studs need a jig to
hold them in place, until the resin is set. This jig is made from wood 380 x 50 x
25mm. It must be made precisely, or the studs will not fit the spine later.
• Make a punch mark at the exact centre of the largest face (see diagram 24).
• Use dividers or compasses to mark arcs at a radius of 178 mm from this mark.
• Punch four marks on these arcs, 30 mm apart and 10mm from the edge.
• Drill through with an 8mm drill (using a smaller size first to be accurate). Use a
drill press, to drill the holes truly square.
• Remove some of the underside of the ends of the piece of wood, so as to prevent
contact with the fibreglass resin.
