29b biscuit joined doors

In this video I want to show you an alternative method for assembling the joints in a frame and panel door

the first thing to understand is that there is a groove of course that runs along here in the rail and

Then another one here that runs down along in the style The groove in the style stops

About here, so it was created with a straight router bit And a router table on a fence so I could stop that groove and that's an important part of this design

But what's going on here is actually two number 20 biscuits that's what these are and

The reason they're visible is Because of the limitations of the width that we have to work with and the way

These biscuits were installed. That's what I want to show you here

So this is a similar door With the the two biscuits I've glued a biscuit on here so you can see what's going on inside

The center line of the biscuit would be about here and That's where you plunge your biscuit slot

So you just adjust the biscuit joiner as you normally would for a number 20 biscuit

So that the slot depth is half The width of the biscuit and then you'd plunge here

swab some glue in the slots Use a flux brush for that it works very well brush a little more glue on the biscuit

Put the two biscuits in place and then bring the style and rails together around the panel with the clamps

now what you're gonna have when you do that is is two biscuits that

Extend up above the edge of the door, but that's no problem because when everything's

Firm and dry you can just saw this off here and sand it flush and now you've got a nice strong

Installation that looks pretty nice too. I know from years of experience that this is plenty strong

Even for a large door that might be four or five feet high and especially for for narrower single panel doors like you'd find in

kitchen cabinets When I've done cabinet making seminars some people ask Why I use number 20 biscuits if they're so long

That they're gonna stick out past the edge of the door and have to be trimmed off and things

Why don't I use a much smaller biscuit one that might fit

entirely Within the width of these members without sticking out past. Well, the short answer is just simply strength

even the smallest biscuit available might not Be useful in a slot that doesn't extend past the edge here because the slots to extend further than the biscuits

But even if the slot did stop and this area was completely

Normal with no slot or biscuit visible The size of the biscuit would be too small, especially the width it wouldn't extend far enough

Into the rail and style to be strong So the answer for why we use biscuits that are this large is because we need

This amount of depth in order to get the strength a smaller biscuit might be able to be hidden here

But it wouldn't be strong enough
