I'll post some pictures tommorow of the ends, it is a steel mandrel, I don't know if when I tapered it, its off center or what. When I turned them I used a live center on my tailstock. Could it be I tightened in down to much? Like I said, I am new to turning and making calls, I am waiting on my flat jig from webfoot, so I am just practicing on some barrels. As far as drilling I am drilling on my lathe, using a chuck jaw and drill chuck. I am going to have to get a drill press, it seems it would make it alot easier. It did seem that teh hole was a little off center when I drilled. Could that be my problem? Maybe the pictures will help
