CarolinaTKE said:Thanks for all the advice! A CO2 discharger won't work, I'm afraid, since it's impossible to get the hammer far enough away from the nipple without it breaking off. I'm probably just going to leave it as it is after another soaking of oil--the barrel started to flake the minute I put a rod in it with my ball puller. I really think it would crack if I applied the necessary pressure to pull whatever it is that's down there. When I said it was fragile, I was not exaggerating, I assure you.
Is it possible to remove the lock? If so, that would give you access to the nipple.
