The door is "beaching" on what must be a slight rise in level in the tiled
floor in the porch behind it, which coincides with the outside sweep of the
door as it opens.

The bit of the (exterior)door that is now scuffing the tiles is actually a
triangular-section timber nose that is attached across the bottom outside
edge of the door to improve weathering. This has probably been in place
since the house was built (c. 1905). The door is a large one compared to
what's typical today, and it's heavy, so I want to take a millimetre or two
off the area that's causing the problem, but I want to do it without
removing the door.

Other than the obvious angle grinder, is there an easy way to do this?

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Appelation Controlee
saying something like:

With the non-removal of the door in mind, I'd think about running a
hacksaw blade along the bottom, in a padsaw handle. Can't you take the
triangular drip section off, to work on it?

Or try a strip of very coarse sandpaper fed under the door and rubbed
backwards and forwards ...I did this once and used a piece of floor
sanding stuff that had been left behind .

Thanks for the suggestions - I already tried sandpaper, but much to-ing and
fro-ing resulted in little change. The timber strip is quite subsantial,
and it's unlikely it could be removed without destroying it. It's as much
part of the door as the mouldings surrounding the panels.
I'll try the hacksaw blade and let you know.

I found you had to do it in a specific way for it to work .The
sandpaper has to be long enough for you to have a good grip on it so
you can exert an upwards force with one hand on each side of the door
..and using a "one side up/other side down" motion ...as I said the
stuff I used was part of a floor sanding belt which has a fabric
backing and doesn't tear .....I think I also tried a blade but found
the trouble with that was it kept bending away from the undersurface
of the door .

Another alternative is a device specifically made for cutting slices
off bottoms of doors in-situ ...cant remember what they are called .

Difficult to get to both ends without taking the door off. Then you
could just use a circular saw and be guaranteed a nice straight cut.

Have the hinges dropped?

If they have it may be better to take the door off and replace the
hinges which will avoid having to hack the bottom of the door.

No the hinges are OK.
In practice the hacksaw blade has done the trick. I cut away about 3mm
depth, which was the least I could achieve, for roughly 75mm inwards from
the outside edge of the door.
The nosing is set slightly lower than the bottom edge of the door, which
would have made working an abrasive strip (in the manner suggested by Mr
Nutter) a bit difficult.

Thanks again to all for the suggestions. :-)
