I need to replace a mag spring on a 20 year old Model 500. I have the receiver stripped, foreend off and a padded vise ready. I have a BIG Strap wrench to twist with, and a witness mark scribed on the tube of the depth in the receiver.
BUT from past experience, the 500's have red loctite on the mag tube threads. Which would you use to heat: a paint-removal heat gun or a propane torch? And would you heat: the steel tube only near the frame or the aluminum frame and tube where they join?
Whats the limit on heat without damaging the receiver?
How do you know when the loctite is ready to go??
Thanks - perklo :?
