The " ALIBOX "

Mark Chase · 27th May 2006, 10:25

Very tempted by the Ali box (cant afford the T one) but I am also concerned about the dissimilar mettles on the top hinge and the stand.

Could a rubber gasket prevent problems?

I assume the back loading version doesn't have a top hinge?

Bolt might be missing but I think it is azimuth perspective from the shot.
Second photo looking down shows it about dead on. Looks right to me.

hole is perfect chaps,just forgot to put it in. good obversation.ill send picture with it in if you like just to prove it.
thanks.

had it on good advice that titanium doe not react with any thing much except oxygen and then only at high pressures or high temperatures.
in aluminium if you drill your holes first and then anodize you shouldnt have any problems.
my aluminium metalsub mounts also have ss fittings,no sign of corrosion there.
even on its own ss will rust a little .diving knives etc, in salt water.
you should get many good years of use.

really!! I blew it up before posting and would swear it is mis-aligned.

....but because you are a NoBo I accept I must be wrong.

Hmmmnnnnn look at the last photo extreme right.

Well, I only looked at the pictures posted by Michael on this thread. The holes definately look mis-aligned on the last picture in the gallery.But hey,hole to hole axis can be easily retified after all this is michael's first piece Alibox.

Cheers,

Can we see some picks of the back off on the back loader. I am especially interested to see how secure the lid is if the meta sub brackets are mounted on the detachable lid.

Michael,

Corrosion on individual metals and alloys is not really that much of an issue, until you bring two different metals together, electrically connect them and put some water in there. Have you tested what is going to happen to the SS stand and screws on the Ti box? And what happens to the Al body when you attach the SS stand? I guess you can try it by putting Al/SS or Ti/SS into tub with seawater.

My guess:
The SS parts will rust on the Ti box and the Al will corrode on the Al box. So I would like to have an idea of how fast.

Only way to prevent this from happening is to avoid the metals from coming into direct contact with each other.

The actual chemistry/physics are beyond my english. I could try in german though :-)

SVEN,

My titanium box is several years old now.. It has SS screws and some hardware (like the main hinge,latch ect).. No problems at all with corrosion.. I only have 1 place that I get any "rusting" and I can usually just wipe that off easily (and its the same place as 100% ss ones react as well)..

Titanium is a strange metal.. not many things react with it (even our body doesn't recognize it and will easily grow over titanium)

Only on RBW would people be arguing about a dodgy screw hole in a tin box.

(Very nice tin box, BTW!)

Just out of interest, do you know how the main section is constructed? I can't see any evidence of a welded seam down the lengh of it (which would lead me to think that it is bend/curved and welded). With an apparently seamless construction like that I can only think it was extruded, but surely the tooling costs for something like that would be astronomical?

I can see that the bottom is welded on, by the way...

Look at the centre picture and there is a seam on the flat section (to right the of the left hand big holes).
It looks like it has been butted and flushed.
Leaving the weld on the flat section saves stressing the weld.
...and looking at the weld bead on the bottom this would make a lot of sense to me!
