What I'd like to show you now is the safest procedure for putting together frame and panel assemblies
0:07
There's a little more here than meets the eye, and I'd like to help you avoid some trouble
0:11
Rule number one is that you never glue up a panel assembly like you see here
0:18
without first a successful dry fitting. The parts have to come together fully
0:24
before you can trust the process to actually use some glue on
0:29
Because once you get the glue in place and you start getting these parts coming together
0:33
if they're not fitting tightly, they're probably not going to come apart to give you another chance
0:37
besides being really messy. So, before I run through a dry fit with this particular mock-up panel
0:46
I just want to point out again how important it is that no glue get on the panels
0:54
Now, you can see here, this is my hand-planed panel, so the bevel is continuous
1:03
It doesn't flatten out. It's a continuous angle, which means that the panel
1:10
does not match exactly with the groove. This is the traditional way of raising panels, and it works fine
1:18
You just have to plane to the point where the outer edge of the groove
1:22
is the same thickness as the panel, as you see it here
1:27
This is a great setup. I've got some stain wiped on here
1:32
If I plan to stain a door like this, I want the stain to extend within the groove
1:36
so that no unstained wood is revealed if the panel shrinks. And when it comes time to actually applying glue, you have to be very careful
1:46
Certainly, you want glue here, and on the end, and here, but you don't want to extend that glue so far that you have a significant amount of squeeze-out and oozing
1:56
that might lock the panel in place. These joints are quite strong, even if you only extend the glue maybe three-quarters of the way along the tenon
2:07
So, dry fitting is pretty simple, and it should be done with every assembly you do
2:16
Now, when it comes to clamping assemblies like this together, you must only apply clamping pressure across the rails
2:28
So, we've got a clamp here and a clamp here. If this was a longer door with an intermediate rail in the middle, I'd have a clamp there too
2:35
But you never clamp in the middle. First of all, the structure has no way of resisting that inward pressure
2:43
so it's going to bow the stiles in. And second of all, there's no point in clamping there
2:48
because there's no glue and there's nothing to force together. So, when you draw the parts together
2:57
and everything looks good, you get a tight joint over here, then you're ready to take it apart again, apply glue, and bring it all together
3:12
Now, in practice, you might find that there could be a little bit of mismatch here
3:17
between the edge of the rail and the ends of the stiles
3:21
But that's no matter, because assemblies like this, doors like this, have been made, you should have made it so it's a little bit larger
3:29
and you'll be planing that so that it fits the door opening perfectly
