You're a brave man Charlie Brown in undertaking this task. Kudos to you! While I enjoy working on guns I have learned from past mistakes to finally listen to the little voice in my head that says, "stop"! don't go any further rather than listen to the counter voice that says, " just a little more, you can do it, you can do it....Oh crap! I actually know my limitations now and I have never regretted since paying for quality work that I can't do myself. I hope you are able to power through it as you say and are happy with the end result. You are right, sometimes it is not a matter of money but a matter of pride and perseverance.
