Seeing it, it's not at all what I expected to find. Does offer some good info though and gives me many options to think about.
*Question: do the reenforcement barriers (blue arrows) have any holes in them or is air flow routed over these barriers? I take it that the brass washer screw is not an eccentric and simply tightens.(?)

I'm doing my best "looking at Mars rover pictures analysis", although a side view of it would help. I ain't got one of these btw.
I believe the blue arrows point to the raised area that allows vacuum to be pulled through the track's channels. The red gasket seals against the product to be cut top surface. And I believe the brass circle is eccentric so as it fits within the track top surface it can clamp by side loading. This unit does afterall fit on the end of the track.
The brass is not eccentric if memory serves me, it slides into the rail joiner groover and just lifts up when tightened. There is no reason for the area you marked with blue arrows to need vacuum, it sits on top of the rail, it's the open part to the right of the picture that provides vacuum to the rail. I think these are reinforcing ribs and provide no other purpose.
I'm 1000km away from the part now, not back for a month, so I can't take any more pics!
Ok, I'm getting pushed into my crumugeon side. It's not my fault.
I don't see how the little tab on the end would handle the forces of clamping or the hose by themselves. I think the disc is an essentric and everything fits into the very specially designed groove up top. On one side there is a bottom groove and the other a dovetail, where I believe the essentric dovetails into.
If we take a very very close look at the adaptor, it shows protrusions for each side of the groove with lead-in reliefs. Also the clearance support ring around the metal disc shows it essentric to the disc. The only reason to design it that way is if the disc moves in an essentric manner. But I concede it also might stay where it is and just moves up or down to lock into the dovetail if it extends into the dovetail no matter what, it's just not what my gut is telling me. Maybe it does both, essentric and changes plane.
I think it's the camera angle and shadow that makes it look eccentric. There's such little room for side to side movement with regards to the dovetail and bottom groove that one of them would risk not having enough bite if an eccentric moved them in one direction or other.
The dealers etc. all told me it was a different track/rail even one who contacted mafell for me. But I could plainly see it was the same, I just got hung up on some posts saying they wished the track was longer, so it made me wonder why they didn't just swap vac parts onto longer track.
My experiments using foam & a hillbilly vac attachment have been encouraging so far with regular F track and I wanted to make sure I wasn't missing something about any 'uniqueness' of the track supplied with Aero.
So you've had luck with your experiments with a home made adapter so far?
I noticed that the Aerofix rails have two metal plates on the bottom and supposedly you can't get suction to work if you join two rails together on the other rail (...Well, I can see that the joints will leak a little, but with enough airflow and static pressure it'd be better than no clamping, right? In thrust we trus-- I mean vacuum power).
abdon: I stand corrected , the angle fence is only attaches with F -Tracks , what confused me was , that the Timberwolf site mentioned it will work with the NFU machine, yes it will work but only I guess when you use the Ftrack , with other tracks Like the KSS L.

glynnco: Did you order from GereedschapPro? I see them as in stock but I'm located in the US and am not sure if they ship here. I sent them an email asking about shipping but it was returned undeliverable...

jonathan: I've purchased a lot of stuff from our neighbours @ GereedschapPro.nl As far as I know they are one of the larger Mafell dealers in the EU. I can recommend them, they usually respond quickly.

lasse: Thanks for the tip! I have own a mafell rail which is 160 cm and one that is 80 cm. Will it work just as well or will I need to buy rail that is 110 cm?
