There have been many over the years.I was always told biscuits were for alignment not strength so no real surprise, It would have been far more interesting if he’d used dowels or even dominoes
I have used biscuits in architraves around doors for years now and not a single one that I know of has opened up.surely the problem with joint failure(at least the type he's talking about) is the movement of the wood over several seasons. mitres in particular show big gaps ie the angle changes at the inside corner. so biscuits seem to stop immediate breaking.
Yes I have seen biscuits used by guys installing fancy trim work, for alignment and help hold it in place whilst glue dries. They do have a place, been around a long time.I have used biscuits in architraves around doors for years now and not a single one that I know of has opened up.
Not so great series of videos. I think some of the tests are unrealistic and cause 'followers' to misunderstand real-use structural situations and could make bad judgements in future as a result of that. There are details which make a difference, and I strongly disagree with end-grain jointing being weak as being a myth. Glue joints end to end should certainly NOT be relied upon for any length of time for any structural situation. Not every follower agrees with the conclusions if you read them, I am just flabbergasted that so many think he is a sort of genius and myth-buster. Even this biscuit joint themed video lacks some reality in practical use situations. Biscuits definitely have their place in the world of jointing, not just for alignment, but the devil is in the detail.Third in a great You Tube glue myths series has just landed. Worth a look if, like me, you have a biscuit cutter.
Me too. Like me I am sure you only use well-seasoned timber. You can't really prevent a mitre-joint from opening if the wood needs to shrink, but if the glue to the biscuit is really good, it is possible to split the wood instead. When biscuit jointing thin timber or mdf I clamp over the biscuit itself if I can which vastly strengthens the joint. Tightness of joint and thin glue-lines add to strength immensely. The simplicity of the joint is marvellous, I wish they were available in miniature, with smaller saw blade but still with similar depth of cut for narrower joints.Yes I have seen biscuits used by guys installing fancy trim work, for alignment and help hold it in place whilst glue dries.
