Fixing architrave and skirting board in place

[curiousorange]

How are architraves usually fixed in place? Looking at my door, I see about half an inch of wood next to the door, and the rest of the width is plaster. How should I fix it?

I have two metre-long lengths of skirting board, joining at right angles, to fix to a plaster surface. How should I do it?

Thanks.

Set the edge of the architrave back about 1/8" from the edge of the door frame. Pin through about 1/8" to 1/4" from the edge of the architrave.
Fixing the skirting,, Either use plugs and screws or consider glueing it with no nails, sticks like s**t or similar. Where they join at right angles (i assume it's either an internal or external corner) either scribe one into the other (internal corner) or mitre them (external corner)

As a matter of interest, why mitre outside corners and not inside ones? I know it's the correct way to do things but I'm curious as to why exactly you should scribe rather than mitre.

I presume this was advised because it is easier than a mitre to do and doesn't look too bad. However, a mitre looks better, in my opinion.

Internal corners are scribed to allow for movement of the timber. If you do a mitre on an internal corner, when the timber shrinks, the mitre will open up far more than a scribed corner would.

Scribing a skirting board - do I use the other board to draw the profile outline, and then saw it? What kind of saw should I use?

Would "No Nails" be OK for the architrave, perhaps with a couple of pins to hold it while drying?

Here's a link to how scribing is done.

I wouldn't use no nails to fix the architrave though. Might work, but you'll still have to pin it well.
