So here is my progress as of tonight. First of all I am unable to remove the forearm because I can not get the screw off. I'm trying, but I'm afraid I'm going to round off the head of the screw. If anyone has any suggestion on how to get it off please let me know. For now I will work around as best as I can with the hope of eventually getting if off so that I can properly work with the barrel. I am a total novice at this, so feel free with offering advice so that I may limit my mistakes.
So I worked on this tonight for less than an hour and here are the results so far.
