MeCCR V'' Mike's electronic Closed Circuit Rebreather - Version II
Again from scratch. Reinvent the second wheel. and again with some specialties !! :-)
With the help of modern 3D CAD tool, Solid Edge, I
designed my new version "in the dry".
Based on my "in water experiences" I was able so simulate in my computer weight distribution etc.
This helped a lot to avoid errors. The holes in the "green connection body" were
difficult to dimension and place.
You can click here to see 3D in your browser.
It's based on Solid Edge, a Siemens product.
On the left side you can run a part tree, on the right you can hide parts
etc...

Never finished ( according to my lovely wife) but operable as mCCR from first day on.

| Specialties |
In situ cleaning, 5 minutes preparation, Mechanical closed sensors Weight system exchangeable versus fixation points Lungs have tube and valves |
The housing is made by fiberglass. The scrubber is double walled and allows
better heat
in the chalk. the lungs are protected between body and separation plate, giving
5 cm of
"flat lounge". Breathing resistance is extraordinary, guess I could have CE. The
green "body"
connecting the scrubber contains also the three mechanically closable sensors.
That allows
cleaning by rinse, no dismounting, that's why lungs have small tubes and valves
to purge liquid.
Pneumatic system uses 25 bar tubes and stainless steel connections.
Last but not least trick is using sailing ships traveller rails to fix the
weights giving superb fine trim
and dismounting them after dive and replace them by normal "rope sliders" allows
travel-fixation.
