Need some advice on a stuck nipple
I recently picked up an 1851 Griswold manufactured 1963. I doubt the nipples have ever been removed. I don't think the gun has been fired. I use a homemade nipple wrench I made with a socket. I was only able to remove 1 of the 6 nipples. I have tried PB Blaster (granted I only let it soak about 10 minutes) but they will not budge.
What can you all recommend in the way of a homemade solvent to loosen them? Or should I just shoot the hell out of it and not worry?
