Bubble Chamber Lense Ring remover


The secret of this tool is that the threaded rods have the same pitch thread as the bubble chamber rings so they retract with the ring, never too loose or too tight. They also hold the ring at right angles to the chamber threads as it is being screwed or unscrewed. Only one tool is attached to its threaded rod, that is the one that is going to remove a ring. The other tool is free to rotate on the threaded rod and serves to hold the "working" tool engaged with its slots.

I have used this tool several times, so far with success. I even managed to re seat a cross threaded ring and remove it without too much difficulty.


Things I get up to.
