Being a bit of a traditionalis, I’ve always made my & M&T joints such that the meeting faces where a ‘perfect fit’, and once together we’re are as far as possible invisible. However, that leaves a sharp corner, at the transition between the long and shirt grain, ie on the edge of the cheeks of the tenons. Paint doesnt stick to sharp corners and over time, the joint can open up at the edge, water get in and it starts to rot. However, the modern way seems to be to add a round over to all edges, such that when the joint comes together there is a v grove at the intersection. This then has v groove protector placed over it which both seals the end grain and also helps to reduce the size of the v groove. There is no sharp corner and the paint / finish will adhere properly. I can see that in theory his is a better way of making the tenon for external applications, but it relies heavily on the v groove protector / filler to keep the end grain dry.
I don’t really like the look of the joint with a v groove, but that’s just personal choice. I have no experience of the longevity of M&Ts made this way, does anyone else have, what’s the view? Old way or new way, which creates external joinery that lasts the longest?
This is the uTube thats got me wondering
