The field coil in my RCA V-210 speaker is open and I know how to electrically replace it if I had to. What I want to do is actually remove the coil and rewind it. I have access to industrial coil winding equipment so that is not an issue but I wanted to get some opinions on removal and re-installation on the speaker frame.
The speaker magnetic assembly is pressed and riveted together and the pole piece is pressed in. I see that I can remove the cone and voice coil relatively easily and am considering using my automobile 20 ton press to press the pole piece out allowing me to remove the field coil for rewinding. However, I am concerned about how to ensure proper centering and a uniform coil gap when I press the pole piece back in. Perhaps a sleeve of the correct diameter and thickness can be use to shim it up as I press it it?
Has anyone done something like this? Any ideas are welcome.
Thanks,
Steve D
