*Special Announcement : June 2001*

**CEDU Research & Development Laboratory**
**is now**
**CAD/CAM Capable**

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**

... 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.

**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.**

**FEOR ClearView with ClearViewDSV**

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