Cutting Scribed internal corners on skirting boards.

Photo 1 - use a coping saw to cut away all the exposed 45° bits (The end grain, or on MDF the exposed stuff) I used my scroll saw as the length was easy enough to handle
Photo 2 - Different view
Photo 3 – when butted up against the last skriting board it now appears to be a mitred cut.



The advantage is that if the skirting boards aren't exactly vertical the joint doesn't open up. Even if the second skirting board is not vertical the joint still doesn't open up. This technique can also be used for more elaborate skriting boards, just takes a bit more time to cut with the coping saw.

Well described, Brian

I thought I had better finish this off. The other end is a basic butt joint. As most if not all plaster walls have a slight rounding in the corner. Puttting a sharp square against this can cause a crack to apear above eth corner. To solve this I put a small chamfer on the back corner of the butt joint.

The other advantage of doing scribed joingts is taht if you cut the board a little short, even 5-10 mm it only shows on the top back corner. A borod short by 5 mm will only leave a triangualr hole of 5 x 5mm. as there is teh light rounding in teh corner this hole is even smllaer and barely noticable.

So how are the fancy period feature skirting boards done?

Same process I think, cut at 45degrees to give edge to follow, coping saw to cut, & file or abrasive to fine tune.
