Yeah, but all the ferrite cores I have are either too big or too small. The bolt sticks out a tad, but not very much.

I found a steel bolt that is of the same diameter and threading as the slug. I put it in and it seems to work fine.

I also found a diddle stick that actually fits the other coils too!

be careful, unlike the original ferrite core, the steel bolt, being highly conductive, is subject to parasitic induction currents and may overheat and damage the coil

Don't ask me how i learned this...

Ai yai yai...

I think I'll just hold off until I get another ferrite core.
