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
