If you were nearby, I'd help you what I could on learning machine work. I don't claim to be a machinist but, I can usually get by. I have a friend close by that is a real good machinist and does gunsmithing work. I can usually get with him if I have any questions on how to machine something. Him and I went to Bartlesville today and bought some 4" aluminum round stock that was listed on Facebook. I don't have a need for it today but, when you can find metal at a good price its worth getting anymore.Man, I kinda wish that I lived closer to you so I could befriend you and learn some of your machining knowledge. I've always liked the idea of being a machinist because I like to do things with my hands, but I went a completely different direction and became an office monkey. Plus, I think I'd enjoy it more as a hobby than as a vocation (like most things).
