I am constructing my first rail and style door. Always before they were M & T doors. When you glue in the stile to the rail there is some end grain. Do you put glue sizing or glue on the end grain to seal it before you glue the door together?

In my cases I am using a flat panel with space balls.

I just put glue on both surfaces and clamp. Haven’t had any failures yet.

Glues today are really strong even with end grain

I always put glue on the tenon and mortise areas (green color). IMO, the shoulder and cheek areas (blue areas) are optional. When you slide the tenon into the mortise, glue will flow out of the mortise onto the cheek and shoulder areas and onto other areas that you do not what the glue to be. Danl

In a recent presentation by Titebond's technical service manager he recommended one of two things:
* apply some glue to the end grain and let it soak in for a few minutes, then add more and assemble the joint

• use the Quick and Thick glue

I've used the latter on many mitered picture frames and it's worked well for me.

However, most of the strength will be on the faces of the tenon, but little more won't hurt.

I just glue the cheeks and edges of the tenon. But with rail stile the tenons are fairly small, adding it to the end can't hurt.
