Because I had some breakages on the Barrel while turning closed ends, I made myself a SUPPORT BUSHING,
Picture 1 shows the Barrel drilled out, and the weakest point,
Picture 2 shows the Bushing inserted and helping support the end,
Picture 3 shows the actual bushing.
The big end of the bushing can only be a certain length because the closed end mandrel has to go in a certain amount to maintain contact at the open end.
I tried it and it helped tremendously. Maybe it has been shown before, so please excuse me if it has been and point me to it so I can learn!, thanks Amos:smile:

Lou, it was very trying when I used up one complete blank and ruined it, so necessity was the mother of invention! It has improved the success rate, I still support the work with the headstock also, but there comes a time when the headstock has to be moved away and then it proves very helpful- still, use plenty of gentleness and sharp tools.

Wow, that is another really smart idea from the forums. I've had the occassional closed end break or collapse right at that exact point.
 
Hi Amos,

good idea in turning a 'bushing".

Q:
Can you use a 'machine' screw (rounded head) and cut the thread to the length required?
