Choice of Tray - Stainless or Delrin?

[kwinter]

Opinions? There seem to be many options for trays in both Delrin or stainless.

Aluminum.

Just make sure that it's not 6531 or else it may have be condemned after a limited no of videos shot

I would go with delrin. It's plenty trough/ strong and a good bit lighter than SS, aluminum is also a good choice. Unless you just need the extra negative buoyancy I see no need to add weight to your luggage. I use aluminum for my trays but then I build them and aluminum is less expensive than large pieces of delrin....go figure, plastic more expensive than metal.

Good point about the travel weight. I was thinking about the stainless to offset the buoyancy of the locline arms and octopus. But adding some lead might be a smarter way to go. As for aluminum, I have always had trouble with salt water corrosion after a while, and the tripod screw and other hardware being stainless would lead to dissimilar metal problems. How do you avoid these problems with aluminum?

I use plastic screws and nuts with Aluminum. These are avail from plastic manuf online. I use them on my marine reef tank and they're incredible strong and light.( If you need a URL, let me know).

I have not had any issues with SS and aluminum, I just rinse/soak the equipment good after each dive. As for buoyancy of the LL arms, I don't find them a problem with my camera and strobe but if you do, just drill a couple of holes in each end and let them fill with water. For screws that remain in place between dives/trips I coat the threads in silicone grease, seem to pretty much stop the corrosion problem.

Drill a tiny hole on each end of the LocLine arms. Lets air out under water... lets water out on the surface.
