Welcome to the forum, Bob. Thanks for sharing the info with us, and I wish you the best in your endeavor. I can appreciate your desire to do this. There are some sharp people on here (I do not include myself in that group) concerning gun building. Be patient. Maybe some of the more knowledgeable here will see your post and offer something that will help.

Best wishes on gathering the info to tackle this venture.

May God bless America and those who defend her.
