I have tried this trick in the past and everytime the pen body just melted into a jumbled mess. I was using a torch to heat up the bolt. This time I used a soldering gun and it appears to have worked just fine.

There is one compensating cap though that it won't adjust as the nut is just too tight. Thankfully its on the secondary side of the IF so B+ involved. Guess I'll have to use my metal driver and play it by ear.
