Continued from the previous post:
Finished coil:
The coil fits the pole piece and speaker frame perfectly, so the next step is to press the pole piece back into the frame while maintaining a uniform .032” voice coil gap.
After I wound this coil, out of curiosity, I re-glued the FR4 bobbin with JB weld and using the side supports wound another coil. It also wound perfectly, so now I have a spare coil or a nice inductor for any filtering needs.
