I need to fit a length of coving along a wall that already has the

possible with the others in situ. Nonetheless, it should work fine
if I cut it to the right length and scribe the right profile at each
end.

So what's the problem? Well, when scribing skirting for example,
it's (relatively) easy to transfer the profile as the face of a
board is close to flat, but the curve of the coving makes this
damned near impossible.

Does anyone have a clever trick for this, or is it just a case of
guess it and use plenty of filler when it goes belly up?

Cut a 45 degree mitre as you normally would, and at the root of the
mitre you will see the exact shape that you need to cut. Using
something like a coping saw, follow that profile - and the coving
will fit over the other one. Measure the distance from root to root
of the existing coving, mark the mitre exactly as you would normally
(from the root to the end) and do the same there.

Cash,
That sounds like the voice of an expert, so now for the question of an
idiot: What do you mean by the root of the mitre? I'm sure it's the
right technical term, but googling only seems to use it, not define
it!

Cheers!

When you cut the mitre from the face to the back - you end up with the
'pointy bit' at the top (end of the coving) - t'other end is the root.

If you are still having problems, I'll try and show you with a couple of
photos (I can't do this at the moment as the old computer is slaving away
backing up several gigabytes of photographs on a USB memory stick).
