Terry, I feel the exact same way! Although, I am fairly confident that it is a self imposed feeling because I think I ask a new question just about every other day.
I'm 35, so I grew up with the internet at my fingertips, as well as books, and so my method of learning my entire adult life has been a combination of both resources. Money is really tight at the moment, so I'm not able to buy every single book I'd like to have to learn about this adventure. Also, there happens to be some absolutely incredibly talented people still participating in this forum, so I would like to get their advice and input while they are doing so. I also only know one person that builds rifles, but he is three and a half hours away and is currently laid up from surgery. Otherwise, I'd probably be at his house everyday bugging him!
With my extremely limited knowledge due to being so green, about the only way I can contribute to this community, which I enjoy participating in even when I don't have questions to be answered, is by asking questions to solve problems and hope that a future builder finds the answers later on.
Your rifle is looking great!
