I once witnessed a long time airline pilot crash a very expensive giant scale RC aircraft on it first flight because he insisted that since he could fly a 747 , he surly could fly a model .
I often wonder if that was the quickest 5000 that he every spent .
As to the book . Again , as others have said Brockway’s book shows you how to make everything your asking about . From the breech plugs to fitting them to barrels , to stock layout and making the lock ..
Seems to me that even IF you have the tools , which I question because not to long ago you stated you didn’t have the ability to make a breech plug . Yet then you ask about drill out bar stock for who knows what grade of metal , on some mysterious machine. Never mind that if its capable of doing that job , surly with some thought you could figure out how to also use it to help you turn breech plugs
My advise to you is to BUY THE BOOK . The cost is a lot cheaper then the hospital bill your enviably heading for..
Seriously your worried about 50.00 and shipping . Have you considered the cost of the locks yet . How about the stock ?
Folks , for the most part im as willing as any of the rest of you when it comes to giving someone the benefit of the doubt and a helping hand .
But lets remember that these guns are not toys . If built wrong they will kill or at the very least maim . hopfuly with any luck its only the person who built it
You all can use your own judgment here . But as for me . I don’t plan on being part of helping this person hurt himself or anyone else .
