    Hi folks. I'm new to the forum, and I'm trying to do my first build. This is a .62 cal, oct to round barrel. I missed with the back(breech end) hole in the tenon and drilled into the barrel. As best as I can measure it is about .080 deep into the barrel. Is this fixable? barrel picture.jpg

    If it is only .060-.080 deep, I wouldn't worry about it.
    It isn't any deeper than some of the dovetail slots commonly machined into the breech area of a barrel and the fact that it is round will cause it to have much lower stresses in it when the barrel is shot than a common dovetail will produce.

    Me TOO! ;) No ones going to even know it's there. I might put some low temp solder on it, but that's just me. I like to cover/fix my screw ups as much as possible. Even a dab of JB Weld will keep dirt, crud, powder residue etc. from collecting there. Evey time I do something like that, and trust me I have, I beat myself up for a week! 15 years of being a machinist doing close tolerance machine work made my already OCD perfectionism even worse, trust me.
    Thanks for sharing, I thought it was just me! :D

    If you drilled a clean hole through you can fit the existing hole with a corresponding diameter rod and essentially fill the hole by peening the drill rod in place. Counter sink both sides and peen away and file flush. Building also is about being creative and "fixing" those uh-oh's!

    Also worth noting I would remove that tenon first before filling the void and replace it with a fresh one.

    I've seen a couple factory barrels drilled like that. Not to worry..., and you know now to double check your measurements prior to drilling. It happens. :D

    I have notched a barrel deeper than that for the front lock bolt to clear.
