Tailstock extension for coring

[Gary Beasley]

I recently got a Oneway coring jig, and watching the video that came with it noted recommendations for a tailstock extension while coring. I thought that prudent seeing how a lot of damage can happen if a blank gets loose while coring. I didnt have a mt extension per se but found an 18mm deep socket fit over the threaded end of my Oneway live center and had a very long drive extension in the toolbox. It took some minor adjusting to center the end in the cored blank and it worked quite well.

Very resourceful.

Gary,
You may have just qualified for the MacGyver award this year.
That would make a nice accessory for the tail-stock live center if a person had an adapter machined to fit into the end and snap into a socket.

If you have the socket extension against a flat piece of wood I think that you ought to drill a shallow hole to capture the extension to hold it in place. Otherwise, it could come flying back at you.

The rpms are not that high and the deep socket keeps it from fallng off easily. I cored several blocks with it and all it did was sag a bit when the bowl separated. You would have to take the coring rig off the lathe to drill the holes so I think hand centering works just fine.
