BP/W -- Nuts and Bolts

[cool_hardware52]

The DSS system is significantly different and you're right... it doesn't need any "nuts and bolts". If you use a DSS plate with a STA or with doubles then, of course, you will need some type of nut... wingnut, some of those fancy delrin jobbers, or whatever.



IMHO, it works... OK.
Still... I prefer an STA for the weight and added stability it provides

Stephen,

When you are using your DSS plate and wing does the tank move at all relative to the plate?

If it does I'd suggest you may not have it properly secured, as this is not the norm.

If there is no relative movement between the tank and the plate using the DSS plate and wing, how does a conventional STA add stability?

Yes, it moves even though it is set up correctly. I'm not the only one who has noticed this.

It isn't that big of a deal. I simply prefer how an STA immediately sets up straight and solid with no parts to wear out or break.

Let's try not to get too far off topic.

Stainless steel hardware... wingnuts, flat washers and lock washers... typically are used by most folks with a standard backplate and STA. Other's use some of the solutions described above and those are fine... but they aren't what's commonly preferred.

Stephen,

If it moves, somethings not set up right. As far as topics, this is a matter you first raised, not me. If you think a new thread appropriate it's fine by me.

I simply stated that I prefer an STA and that I prefer to use the standard wingnuts... that was the original topic.

If you want to talk about how stable your rig is then, yes, I think you should start a new thread.

I've never noticed any movement of tank realtive to plate on my DSS rig. The built in STA does its job very well, and the compressible rubber wedge thingies really help tighten the cam straps down.

I see you don't have too many dives, so that explains your point of view, but as soon you have to sit out a dive I bet next time, you'll have a save a dive kit so big, that you may need a separate box for it.

I got everything I need and some things I may never use. One time the first stage dust cover crumbled to small pieces in my hand when installing it after the first dive of the day (not a big deal, but can lead to water entering the 1st stage if not very carefull), I got one on my save a dive, and the reg was protected again in no time.
I also carry an old spare lp hose in case one of mine blows.

I've seen blown neck o-rings, lp hoses, 1st stage dust filter snap-ring break, ect.

I carry the SCUBA tool, but also carry the adj. wrenches, pliers, and drivers 'cause the SCUBA tool is very brute on the gear and will mark and chip most of the cromium it touches.

I'll grant that I would feel different if I was on a liveabord for a week in Galapagos, but that's not really what I'm talking about. I actually do mostly beach dives with the occasional boat trip, 2 days max, and local, so the impact of a dive day scrubbed due to gear wouldn't be the end of the world, not that I would enjoy it.

I was mostly exagerating. I do have a save a dive kit that I'm assembling. That said, again considering my unique (somewhat) circumstances, I can't imagine any of the boats I dove on wouldn't have damn near anything I'd need short of a fully redundant set of gear.

I may not have 500 dives, but I have enough to know what is important to me... under the circumstances I currently find myself in. And actually, I forgot to update my profile... I crossed the 50 dive threshold a couple weeks back, and have quite a dive schedule ahead of me in the next few months.

mcmaster.com has a good selection of titanium or 316 stainless screws that would be acceptable for a backplate. Just my 2 cents.

McMaster-Carr is a great resource, I use them all the time. I'm always amazed a the range of goods they have in stock.

Minor point, if your BP is Stainless, I'd recommend you stick with Stainless, or nonmetallic fasteners. Dissimilar metals will eventually corrode.

Oh~~ Yeah... But, we are unlikely to disclose any info for other fellow diver's business...
