Having trouble with architrave

[HawkEye244]

Hi chaps.

I'm really struggling to fit a reasonable architrave to one of the doors.

The reason is that I cannot fit a full width of architrave (70mm) and so have to strip down the width of it to approximately 30mm (not much).

I understand the usual method, and this is what I do:

• use set square to run 6mm around perimeter of door lining
  
  offer head rail and mark on wall
  
  offer side rail and mark, then cut and fit
  
  repeat for other side rail
  
  offer head rail to wall and mark on where the cuts are and then cut and fit head plate
  
  done
  

What I don't understand is that by cutting the architrave in half suddenly doing the above results in a bizarre misconfiguration and the profile no longer matches up.

This is because obviously one width is different to the other but even using a bevel I am getting strange errors.

I am hoping there is a method to overcome this problem ?

Thanks guys

Also in this instance I can't recess the architrave into the wall because it butts up to another architrave of an adjacent door

ARghh did some routing about and came across this thread :

exactly what I was after.

Seems the procedure is the reverse of normal,

so start by cutting the header with 45 degree mitres and THEN mark the side rails accordingly and make cuts.

This is totally counter-intuitive for me , sorry to say I've messed up a few trying to get it right.

Few quid wasted, never-mind, onwards and upwards

I'm assuming that you are trying to cut a mitre across the full width of both pieces and you are finding the mouldings are not lining up? If that is the case you'll be better off keeping the cuts closer to 45* . This will give you a square cut across 40mm of the head piece.

Seem to have been writing at the same time so didn't see your last post.

Yup got it now, shame I've wasted 2 lengths @ 2.1m and a header but hey ho, firewood I guess lol
