So glad to be a member of this forum. I've been working on my first "non-kit" gun, an S. Hawken halfstock in .54. So far I've got the barrel and tang inlet nicely so next I went to work on the lock. The lock is a Bob Roller that I bought 15 years or so ago (for the unbelievable price of $25!) so I had to fit the snail into the lock. I took my time and had what looked to be a tight fit with the hammer striking the nipple as purty as you please. Then I went about inletting the lock into the stock, which I was nervous about, but I got that done and the lines along the lock plate look sweet and I'm breathing a sigh of relief when I notice that when everything's fitted together in the stock there's a .5 to .75 millimeter gap at the bottom of the snail where it fits into the lock plate. Now, I looked to make sure there wasn't any wood throwing things askew and there isn't, so I guess my previous assessment of my work wasn't quite accurate. Well, I knew that something would come up sooner or later and it's really not that noticeable, but my question is...is there anything I can do to fill in that gap in the metal to metal fit? I'll probably be the only one to notice it but I just had to tap into the collective wisdom of this board. Thanks, Bearman
