I am tiring to put new pine torus skirting boards in my room but really struggling with cutting the wood to create a 45 degree angle for the corners. Does anyone have any advise on the best way to do this?
Unfortunately when two walls meet the angle is rarely exactly 90 degrees!
First of all you need to have a device for cutting wood at an angle, B&Q do a cheap one that you operate by hand, you can select quite a few angles and the saw blade is fine enough not to damage ssmaller pieces of wood.
The easy option is to by a compound mitre saw, again B&Q are knocking these out cheap at the moment for £30-40.
Anyway you'll have to read the instructions on their operation, the important bit is finding out what angle exists between yor walls, you can either buy an angle finder, screw two bits of straight wood together or use trial and error.
I prefer trial and error as its quicker, get two offcuts of the skirting (not too long) and cut one at 45 degrees this represents one length of the skirting, then cut the other at 45 degrees but the other way round. These should join nicely in your hands to form a corner, put them against the actual corner and see if any gaps appear when both pieces are flush against the wall.
If you get a gap at the front then your wall must be more than 90 degrees, simply get another offcut and increase the cutting angle on your machine to 46 degrees and keep doing this until you get a good match at the wall, remember what angle worked with the offcuts and cut your skirting.
