I think part of the problem is that I've run out of patience.
I've had the frame for a over a year now and it's still stuck. I try about once every week or two for a few minutes to over an hour. I think I'm just gonna have to resort to some harder method (like lye) or have a machine shop do it. I think my will to do it myself is gone after having exhausted to much effort on it for no results.
