With the union of  Computer Aided Design Software to the  Numeric Control Milling Machine, the CEDU has ventured into the world of Computer Aided Designing / Computer Aided Manufacturing.

        The first item to be CAD/CAM'ed is a Cage for a One Way "Mushroom" Valve.  These valves are found in the biteblock of double hose regulators, and in the dive/surface valves of most of our rebreathers.

        I will no longer scavenge the cages from old double hose regulators .   I may even get to replace some that I have borrowed before the original owner finds out that they are missing. ( Thanks Ron.)

One small step for the CEDU.

From Design to Product

Start with an Idea.....

... get the idea down on paper,    plan the machining sequence....
Make the part.

(L) Nylon Cage hot off the Mill,         (R) Cage with 29mm Silicone "Mushroom" in place.

We should remember our past.

These One-Way valves have been used successfully in the FEOR ClearView.
Turned on a lathe, drilled in drillpress. Flat Latex sheeting (.015") for valve,  held in with machine screw.

    Now wasn't that easy.

    Of course this " proprietary information (i.e.. how things are manufactured or produced, components used etc.) may be edited out", ....if and when I, or some fictitious cover organization, actually produce a product for the overseas and/or gray market, ... from some offshore manufacturing shipping container or other sweatshop that is   hidden away in some 'mountain' jungle or something, ...in the name of value added to the product, and plausable deniability .

Smile,

Addendum:

This valve is not the end all. (Actually it still is evolving and being modified as we speak.)   It is only one part of a system, in this case the system is... the ClearView DSV.
 
 

(Of course I still have a soft spot in my heart for those modified HomeDepot Ball Valves.  But time marches on.)
