Oh, there is no doubt that I can't pull it back out.
Agree that it looks like more than 1/4" in the photo, but I measured it. My next step is to see if I can pick up a pipe fitting today that is nearly same diameter as the okie. I'm going to pound on that and see if it does the trick. I'll be sure to stay away from the inner edge of the okie so as to not beat up the brass bushing. I think part of my problem is that a lot of the force was being absorbed by the wood block.
