I recently purchased a morse taper adapter to use in my tail stock when using my Oneway Coring System. I used it the other day for the first time and now my live center is stuck in the adapter. The adapter has a slot designed to assist in getting the live center out, the problem is, the shaft on the live center does not extend down into the opening. I've tried to use a screw driver and hammer to knock the live center out, but have had no success. Any suggestions or ideas would be greatly appreciated. (It's the live center my wife usually uses )
