I'm using a 3/8" threaded BS mandrel and 3/8" Bottom Tap form AS and using Ruth Niles SS threaded stopper. Out of the 15 or so stoppers I've turned since before x-mas only 4 of them I've been able to not strip the threads on the wood blank. These I've drilled out bigger and used the dowel/cork stoppers to keep them from being a total loss. I've seen the ways Ed Davidson has shown to mount the stoppers, this is the reason for I purchased the mandrel/tap.
Using what tools mentioned, what may be the steps that I should be performing that I'm not. Or, is there an instructional dvd that uses these tools. I've learned about pens this way, but don't want to purchase a dvd that doesn't use the tools mentioned.
I don't mind having threads strip, as I know this does happen. I'd rather have the failure ratio of the stripped threads be the other way or not at all. It gives me more of a market to sell cheaper stoppers. But I'd rather have my threaded blanks more predicable than they are.
Thanks!
