Suggested lengths of flexible tails:
coils 1 and 6 - 800 mm flex
coils 2 and 5 - 600 mm flex
coils 3 and 4 - 400 mm flex
• Cover the soldered joints with sleeving. Leave no bare copper showing.
• Label the tails with the coil number and the letter A or B.
A is for the start of the coil, B is for the finish. Do not mix them up.
Or use two colours: black flex for the starts and white for the finishes.
• Lay the coils out in the outer mould.
• Check that they will fit comfortably, and that the tails are long enough to remain
within the mould until the exit point between coils 3 and 4.
It is important to lay all the coils the same way up.

Preparations for stator casting
The stator casting will contain:-
• six coils
• polyester resin and talcum powder (and perhaps pigment)
• fibreglass mat (CSM)
• four studs of 8mm x 100mm threaded rod
Also, be sure to have the moulds prepared properly. Sand them, seal them, polish
them. If PVA release agent can be got, then use it.
