New dromedary bladder

[lexvil]

Bad anology on the bicycle, DIY is nothing more than putting the proper part on yourself rather than packing the bike into the car and taking it to a shop. The bent coat hanger repair and the basic understanding of how things work could save that child if they were far off of the beaten path with no “proper” parts available. There was a time when the only way to get something was to make it yourself or adapt something not intended for diving for use in diving and sometimes it’s still the better way, I have a few pony bottles, on with a commercially available sling and the other with a sling a made from poly rope, I actually the rope one over the comerician one, they both work well but the home made one is more adjustable and compact.

Overall DIY is a good thing for some, maybe most, people.

What pressures do you think the bladder is going to see? I help you out, the pressure differential is the important factor and that is quite small ......

As for the testing criteria used: can you please list the standards, bladders used for scuba are tested against?

I think you're getting fear confused with respect...

As for Gear Standards...read...UCSC Standards for Diving Equipment...and HSC Performance of Diving Equipment Standards...

Helpful reading while you're deciding on a BCD bladder...

Please feel free to proceed as you see fit...

The analogy is no worse than the bad suggestions

Besides...removing most of your narrative...I think you said the same thing I did...and...you could always walk the bike back...and finally...I think the bike took kit would more likely be equipped with a spare master link and clip than a piece of coat hanger wire...

There should be a category on ScubaBoard... entitled...''In Defense of Lost Causes and Bad Ideas''...you guys would have a field-day...

We did almost say the same thing and while I don’t really get the point of this bladder thing unless someone is thinking this will be better than what is easily obtainable, sometimes it’s just for fun and to see if one can do something, I think it proves helpful to others, sometimes in that they can see how good some off the shelf stuff is. It the root of innovation.

As you mentioned up thread we are mainly recreational divers. I enjoy my hobby without the limitations imposed on the commercial or scientific dive community.

Their protocols and equipment recommendations are also fairly unsafe and unsuitable for the caves where I do use a drink bladder as a BCD.

Being a thinking diver is important in adapting and creating the tools we personally find enhance the way we enjoy our hobby.

I've personally found great pleasure diving DIY scuba gear.

Note the relative condition of the bladder.

It was my go compact rig for upwards of 800 dive hrs, been below 280ft dozens of times, 2.5hrs from the surface in a cave system frequently, also in 34° waters. My rig of choice 18 hrs from a chamber in the arctic ocean. Never failed on a dive or required any service. (lost the cap and made the replacement a dozen dives before I retired it, otherwise its the original components)

Take off the rusted out harness and I could likely still sell the bladder as 'in decent condition, showing some signs of use'. It isn't for sale.

I'd like to see a comparatively priced bcd with this level of dependable durability sold at a dive shop.

This is why I enjoy using DIY parts in my hobby.

Back on topic, I don't know the durability of the later model of MSR bag but if it's as good as the original model, I'd not hesitate to put one to use. My current BCD also is a MSR bag but came from a dive equipment company (via SB used gear sales)

Northernone...

I get it...believe me...

I can't help but asking...would you fab one of these up for someone else to use...or loan yours out for someone else to use...

I believe I know the answer...please don't surprise me...

Best...

Half the fun of DIY is DIYing the DIY. I learned about the MSR bag from smarter divers than I. I appreciate when a fellow tinkerer with particular skills shares the creation with the group or even sell components to help the rest of us out.

But the exchange of knowledge and problem solving thinking is what I enjoy most about the DIY community. The internet has helped greatly, I use to lurk the forums in the early 2000s before eventually signed up to share as well as take... If I had this resource as a younger child I could have avoided some near misses. Reinventing the wheel in isolation is a slow way to progress.

Learning the design and function of an object prior to its use has good value to me.

You mentioned rebreathers earlier:
TP2000
With respect to a designer who did much for rebreather safety. (Smither's code)

Please pardon my ignorance but I am not sure I understand...
Do you use the dromedary bladder with a sidemount like in the video below?

I do know I am confused a lot, but not in this case. I am also not sure what a University of Santa Cruz standard for a scientific diver has to to with bladders for BCDs (In the future it may be helpful to make your point by posting a link or attaching the document in question). Besides, as long as these so called 'standards" are not biding, they are pretty worthless.

You also conveniently avoided to address the point about the pressure differential in the bladder, which brings up the main point here imo: A thinking diver is a safe diver.

A lot of ''Standards'' are not binding...or developed into legislation...however they do represent ''Best Practice''

Why would anyone want to consider anything less than ''best''...

I used to dive with a guy whose common phrase was...''I don't care what it looks like...as long as it works''...unfortunately...most of the time...it never did...when I finally refused to field strip and repair his ''gear'' he started diving with something better...it's so nice not to bring half my shop with me now when I pack to dive...

As I suggested previously...carry on as you see fit...we do not agree on principle...any further replies in either direction are pointless...
