Hi, I need to fit my skirting around an octaganal shaped bay area and dont want to mitre the internal joins but am confused how to cut them so they fit correctly. The skirting is chamferred edge which is causing the problem.
Hi. Traditional methods evolved to deal with traditional materials. IMHO the old methods are not always better. Traditionally you wouldnâ€™t mitre internal joints because as the timber shrinks, an unsightly gap would open up. (Iâ€™ve said on here before that wood doesnâ€™t shrink along its length, in fact is does, but only marginally. It only matters on long runs). Mitres are also not very tolerant of error; both the length and angle have to be accurate. Both these facts mean that for a skilled carpenter with only hand tools a scribe joint (one where the end of one length is shaped to fit the profile of the other) is overall faster, safer and therefore more profitable!
Modern skirting made from MDF wonâ€™t shrink, and a mitre saw removes a lot of the accuracy problem.
So unless you are using solid real wood Iâ€™d be inclined to use internal mitres as per the good Doctors advice. Might not be what the â€œprosâ€
