Rod,
My dad and I built a new rig for the deep dive I'm going to do with you next
month in those Florida caves you've told me so much about.
We took a full sized oxygen tank from his old welding set, and drained off
some of the O2 - we then pumped it up to about 6000 psi with some air from
his auto repair shop garage. We kinda guessed that the PPO2 was about 1.2 or
so, since it took us both about 4-5 cigarette breaks to completely fill the
tank. We had my mom test it out (since Dad and I were watching the game and
drinking beer), and it took her a while to pass out (she's pretty weak), so I
figured the mix was about right.
We then built a harness for it with some old handcuffs that he had lying
around - they'll lock over my forearms to hold the tank steady (yeah, it'll
restrict my mobility a bit, but it's worth it to go deep...).
For deco, we came up with a pretty interesting rig too, we bought 300 ft. of
garden hose from Home Depot, and superglued a Micra 2d stage to the end of
it. The boat tenders (John's mom has volunteered for that job) will just
have to blow real hard into the other end of the hose, thereby giving us all
the air we need...
I'm still working on the depleted uranium weights, which I figured we could
just zip-tie to our ankles (to keep them as far away from our 'nads as
possible).
And for getting in/out quickly, my dad rigged up one of the old jets from his
jacuzzi that mounts on the bottom of the O2 tank. I'll have to carry 4 Die
Hard batteries, with a 12v/120v converter to power it, but that just means I
can lose one of the uranium weights. I figured I should get about 20-30
knots out of that baby, which will make getting back into the cave quickly a
breeze...
If you have a spare $29.95 I can have him build you a similar rig (we still
have the acetylene tank left over) - or you can just use that old CCR-155 of
yours and watch me with envy...
See ya, deep brother...
