The guy that sold 22lr plans. Advertised in SGN all the time. A true machinist bud of mine did one. When I was nutznboltz here I sold or gave him samples of brass screws or bolts and when he walked into the shop and laid it on the counter fun was had by all! We had a great conversation and my boss was going ballistic. It was fun. Anyway i'll try to find the guy in SGN for the info.
