I kinda need some info...I have a horn of which the plug for the spout no longer fits tightly. No Problem with me making a new one but it appears that the hole for the plug has no taper to it whatsoever. Was wondering if I took a rat tail file and sort of chamfered the begining of the hole or...got one of those tapered drills and gave the hole a true taper...which would be the better to do? Also...from what I have seen on Ebay..those buffalo horns..those critters like an antelope..the horns are not attached to the skull? Or...are they not buffalo horns at all? Reason I am asking is I kind of would like to make a powder horn out of one..but they seem awfully thin and have my doubts as to the strength or longevity of them. Comments?
