Hello I know what a mitre angle is and I know the tools I can use to do it, so with nearly every project where I'm fitting new skirting or scotia to out of square walls, I just end up filling the gaps where it most notices and it never looks professional. So (a) what do you use to measure the angle - either inside or outside - say for skirting against walls, B&Q only sell an angled bevel and that has no graduation on and (b) what do you use to cut given that every mitre saw I've seen/used has pre-set degree gauges - 45, 22.5 etc - not 40.6 or 46.2 degrees, for example! Cheers
If you notice professionally fitted skirting internal corners are not mitred at all only external corners use 45 degree angles. It is possible therefore to fit skirting in a square room without using a single angled cut.
