Been meaning to have a go at this for ages so here goes.

This is to link Sli NV-68/78 blocks so they can fit motherboards with a 40mm spacing between slots as appose the the Asus A8N which is 60mm.

The problem being is that once the cards and blocks are mounted there is only 18mm between inlet and outlet which is too small a space to use barbs and a piece of hose so the only thing i could come up with was to braze two cut off barbs together which will fit perfect though will be a little hard to fit as the cards will have to be mounted to the blocks then the blocks rotated together so the barbs screw into them.

Anyway this is how i've gone about it...

Take two standard Hi-Flow Danger Den barbs

Cut one of the hose tails off all together and leave 8mm on the other

This is it prepared to be heated with the red flux to help the little bits of cut brazing rod flow round the seam when melted.

Now the fun part:D - heat it into submission, well until the little bits of brass melt

And here's the charred end result.....looks a little sad at present but will be back looking good with a bit of TLC :cool:

Is it possible to make a 40mm one for the SLI boards with PCI-E slots closer together? :)

That's what this is for.

If you remember the problem i had with the Dualmaster (http://www.coolercases.co.uk/forums/showthread.php?t=19) as it was only 40mm i decided to make something that would work.........and this is it :cool:

Nice work so far, but couldn't you just do this with an appropiate size piece of pipe and the correct die to cut the threads.

If the cuts aren't square, or if it solders on the piss/off center, then you could run into problems fitting the cards/blocks.

Guess you could do tbh but you need something to stop water leaking out the thread and something for the rubber "O" ring to butt up against.
