I am having a go at replacing the old tired skirting board in my new house. To cover the gap in the wood flooring I am using 25mm thick x 120mm high MDF skirting. I tried cutting the external mitres by hand & soon realised it would be easier using an electric mitre saw so I purchased a cheap Evolution saw which can cut 125mm x 35mm. When I was trying to cut the external mitres by hand I noticed that some of the corners were over 90°. I used a bevel protractor to dissect the angle & then transferred this onto the skirting board. However, I am now coming to the conclusion that the mitre saw I have purchased is not going to allow me to cut a bevel angle greater than 45°& I am unable to stand the board on its end & use the mitre option. Am I missing something here or have I purchased the wrong size mitre saw? Just to add that the mitre saw will only allow me to swing it one way to cut a bevel from 0° to 45°.
