The door was planed to the same thickness as the stiles, and then I squared it up on the shooting board.
The original version of this little cabinet has battens that are nailed on to keep the door flat. Since I have taken the trouble to make blind dovetails for the case instead of using nails, I figured that i'd might as well attach battens using sliding dovetails.
At home I have a special plane for that purpose, but I didn't bring it with me, so I'll use a slightly different approach.
My idea came after chatting with Brian Eve over at Toolerable. He showed me a picture where he had done it this way, and I wanted to try it out myself.
First I made a set of battens that tapered slightly in width. I planed the narrow sides of the battens at an angle.
I then used the battens themselves as sort of a template to guide my saw.
A thing to remember is that it should be possible later on to tighten up on the battens if they become loose. So the taper on the door part needs to be a bit narrower than the battens.
After sawing out the sides for the door part of the sliding dovetails, I removed the waste with a chisel and followed up with my router plane.
I added a small chamfer to the end of the battens, to soften up their appearance before inserting them in the door and tapping them into place. This should also prevent any grain blow out if someone hits them harder with a hammer in the future.
With door at the correct width, I was able to establish the width of my two stiles. These were ripped to the correct width and the sides cleaned up with a plane.
I crosscut them what I believed was the correct length and followed up with the shooting board to make a fine fit. Somehow I managed to make them bot a bit short, but not enough to warrant making a new set.
When that was done I simply glued them into place. A few brads or nails would make it even stronger, but I doubt that strength is much needed with a cabinet of this size.
