old "72cf" steelies

Postby ChuckyBob » Mon Mar 08, 2010 6:07 pm

Just scored me 3 old skool steel "72cf" tanks for $34 each. The tank with the newest test is 10 years old but these things were built like...... eeer tanks right :lol:

They are all rust free externally and inside there is a small amount but nothing to be concerned with.

Anyway, has anyone used these as slings?
From what I gather they have similar buoyancy characteristics to ali 80s.

Threw a pair of bands ( for 12in fabers) around 2 and they worked but gave a centre to centre of 225mm. Standard manifold is 216mm. I will try a manifold on them soon.

twined and a single.

The 2 I twinned up are USD's and have an internal coating which appears to be in fairly good condition.

Off to the LDS to get hydros tomorrow and I will look at modifing the bands when I get the manifold.

Very retro....quite odd shaped at the break aren't they...interesting to see what they look like with a manifold on.
The Dive Dr do manifolds for about $300 which are pretty nice and at that price are excellent value..

Yeah, they should go nicely with my SP 109 2nd stages which are some what older again.

I may keep my eye out for an old skool manifold too, those ones with no isolation valve and an old BC and mask.

Wearing old skool or vintage stuff is so so cool
Wear the latest techno gear/stuff for those training dives or challenging dives ...the dives that matter,
but when just getting out for a relaxing splash - definately retro (like a nice drive in a MG or something).
I got some good attention from just using an old J-Valve for a while.
I would love to do a hard-hat dive some day with the Historical Society, etc, Porpoise Tanks, etc, etc.
Just drifting along with whatever is current.

Ha ha ha yeah I just made myself a Retro Hog rig for diving in the pool and just baby dives in perfect conditions in a wetsuit. (Not often in Welly :lol: )
Its a U.S Divers Conshelf SE2 first (yoke) and second stage, and a Calypso Octi as the primary on the long hose,and oddly enough it breathes exceptionally well.
The Conshelf SE2 was actually the very first regulator I ever owned,that coupled with a Calypso BCD...I was untouchable...!! :D

Excellent! (Would love to see a pic!)
Sounds like you're a well balanced Diver with the latest on one side and retro on the other.
I only have an old Reg, BCD and flippers from around the 90's along with what my father-n-law used during the 70's/80's.
My J-Valve will become a money-box as it should never be used again as it is the same make/serial no./material as the one that exploded at South-West Rocks last year.

...I'll go take a photo.

Yeah that's a U.S Divers Conshelf as well the reg looks like a SE2 second stage but the faced black unit was a PRO-DIVER or something I think,I think it was a slightly higher spec but I am not sure on that.
Nice regs.....I tried to paint the face on one of mine black but the paint was off after one dive ha ha ha ha :D

Yeah, I think they were definately from the Recreational range (and that very colourful 80's period).
Maybe try a 'metallic' texter-pen. I use it on my gear along with some engraving as I'm sick of people trying to pilfer on boat dives due to the gear looking the same. I takes around x25 dives before I have to redo my fins (nearly stolen when I was boat sick but not sick enough to snatch em back!).

Don't do that Nem! The yellow looks cool.
Leave it as is - if you leave in it's original state you might be able to sell them on Antiques Road Show in the next year or so

I got jealous of the close up so here's another take.

P1020480.JPG


The other is an Australian made AirDive (probably defunct these days?)
Picked the US-Divers up for $60 Reg/BCD/Fins

...if you look at how I hang my boots (up further) - I just use Ironing Hangers $2.50
