I spoke with Alan at Wealden regarding the adjustable cutter. He got back to me very promptly, very nice chap to talk with. He outlined a couple of issues and a some possible solutions.
Given that inner spacing shims that would have to be re-manufactured to go inside the cutter case, he said that the tooling cost (NB: they are punched out of steel) would be too high to produce just a handful.
Using a 30mm to 20mm 'top hat' reducing bush may work - but the height of it needs to be determined by how the cutter is packed. You'll already know that the MF-VN 25 requires you to install unused shims on the outside of the adjustable cutter to secure the cutter on the spindle. I'll need to check the required width. He suggested that a local engineering shop would be able to produce some of these.
Another option he said may be worth considering is to ask USA manufacturers. He said that 3/4" (19.05mm) cutter heads are fairly common there, and that it wouldn't be too big a task to machine these up to 20mm. The point being made here is that it's technically easier to *increase* the bore size than it is to *reduce* it. You might simply clamp them and re-bore them to an increase of 1mm.
I'll therefore look at the top-hat solution. Can a USA based MUFfer please look at the 3/4" to 20mmm bore increase option on our behalf? NB: cutter diameter must be 4.75" (120mm) max.
Guy pulled out an older version one of these on a job last week and it reminded me of this thread. Makita 3803A. It's heavy, about $900 / £1170, but it goes from ½" / 12mm to 1-7/16" / 39mm. I think I saw a ⅜" aftermarket blade too when I went searching for it. Seems that because of the depth of cut it could be adapted to ride atop a track.
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?
