With no pin in,if you hold barrel tight in channel,is the hole located in the wood wrong or is the hole in the lug too low?If the hole in the wood is ok,then I think you would have to put in a new lug and re drill or maybe? braze the hole shut and redrill? If the hole in the wood is way off I think you'd have to fill it with a dowel and redrill.I've only done one of those (last summer).Good luck,take yer time, ridjrunr
