Thanks guys. The littel ice cube thing in the center is plexy. Its the thickness Hugh calls for. Its also the same dimensions as the magnets.
I've just cut up 6 of these and just leave them in the coil center and then just poure the reson right over them and they become part of the stator. So far seems to work quite well.
I had to change the speaker basket support to another brand. It needed to be about an 1/8" smaller diameter. I'll be drilling mounting holes in it tommorow.
I hope to poure the reson and cast the stator this sunday.
