6 mm or 8mm router bit and a guide fence on the router?

If it's on the door then I just use longer rods and a second fence. Then use the right size cutter which these days is 15mm wide.

thanks for your replys guys

Yep. The correct size cutter and two fences either side. No need for jigs. Even one fence is enough.

or, buy a dedicated cutter for your router. Save you lots of time setting up and pretty much failsafe.

The dedicated cutters aren't quite right (practically), although they obviously work a dream for fire seal, but for fire and smoke they aren't quite deep enough.

For what its worth we do all ours on the spindle moulder

That is what I was referring to. If you buy the correct one to match the seal you are using, whether it be fire or fire and smoke they work a treat.

quck edit, Ironmongery direct list their cutters on the same page as the corresponding seals. HTH, neiol

1 Fence works, clamp a thick piece of timber down one side of the edge to give the router extra support.
