My automatically retractible interior threading tool

[Okapi]

Here is my last creation on a Tripan 111 basis, an interior threading tool with manual or pneumatic retraction of the tool, the command of the pneumatic device is simply made with a bistable ditributor commanded with a pneumatic mini Festo detector.


And you can see all pictures of the system here : porte-outil de filetage intérieur à dégagement automatisé | lecollectionneur.ch | Pierre_G.

This is the final version after a lot of different models which have always something not perfect for my use, here is the still improvable version but yet it makes the job as I need and want !
