Master Carpenter Video: How To Fit Inset Cabinet Doors

Fine Homebuilding goes on the road to learn the ins and outs of what it means to be a master carpenter



Senior editor Chuck Bickford: I first met Scott Gibson when I came to work for Fine Homebuilding. At that time he was the editor of Fine Woodworking, and he had already worked at Fine Homebuilding and was the editor-in-chief of Home Furniture. I soon found out that in addition to being a great journalist, he was a really good carpenter and woodworker-and he had a whole house full of furniture to prove it. Scott moved up to Maine in 2000 to be a freelance writer, and he built himself a really nice shop so he could keep his hands busy in between typing. I caught up with him while he was making kitchen cabinets for his son, Ben, and I asked him about the inset doors, always a tricky stage in cabinetmaking.

Signature details for kitchen cabinets

Planning your kitchen: Five tools for layout

Scott Gibson: Most cabinet doors today are overlay. They don't fit inside of an opening. I like doors that are set right inside the cabinet, like that; that are cut exactly all the way around-they look better to me. The way I do that is to make a door that fits the opening, exactly the same size. I set a shim at the bottom of the door. Then I fit the hinge side, the top, and then the strike side; put the mortised hinges in, hang the door, and then do the final fit. That's it.

I glue up and build the door to match the opening. I don't subtract anything to make the space around the edge of the door-I make the door to fill the opening. Then I remove material to make it fit perfectly. The first thing I've done here is cut a shim for the bottom of the door, to reveal the space I want between the bottom of the door and the cabinet. I've also planed the bottom of the door so it's nice and flat, removing any inconsistencies from the glue-up.

Set the door in the opening and push it hard against the hinge side. This door fits pretty well, but needs a little taken off at the bottom. I trim that up first, so I have a square angle. I take a plane and hold it 90 degrees to the edge of the door, and just plane off that corner and taper it so that the door fits nice and snug all the way down the length of the cabinet. It's trial and error; there's no magic here.

After I've taken off some of the corner with a short plane, I really want the taper to be nice and flat all the way down, so I go back to a jointer plane. When I'm done, it won't need sanding. It's nice and square.

Because the door is made to the full width and height of the opening, we know one end of it will be too big. I make a mark on each side where I want the door to fit into the opening. Then I make the cut on the tablesaw.

Put the door in a crosscut sled on the tablesaw. I've got my two marks on top of the door, showing where I want it to go. The first thing I look at is whether those marks line up with the sawblade for a square cut. The cut marks are right on the saw kerf of the sled. If I had to make a tapered cut, at a mark lower than the one I've already penciled on the top of the door, I'd put that mark on the saw kerf-where the edge of the blade will be-and use a shim to hold the door steady against the fence. But with the straight cut I have to make, the door itself will be flat against the fence, to get a square cut along the top.

After I make the first cut on the tablesaw, I bring the door back to the cabinet and pop it into the opening. I want to be sure it was the right cut. I can see that the line we established was just right. Now, how much do we want to take off the door so the reveal at the bottom equals that at the top? I mark it by eye, then go back to the sled on the tablesaw and make a second cut.

I've made the second pass on the tablesaw and now I'm trying to get pretty close to what the opening is-and it's pretty close. There's a tiny bit of inconsistency. The gap on the top left is probably a little bit less than the gap on the top right of the door. Your eye really will see that. But I'm not going to fuss with the tablesaw any more. The little microadjustments I can do with a handplane.

Three sides of the door fit, so now I take a look at the strike side of the door, and down at the bottom is a tiny gap. At the top it's a little tight. To make getting the right fit easier, I use a straightedge and make a mark right down the length of the door that needs to be trimmed. It's a guide; I just want a rough idea of where the door should be at. The best way to do that is to remove some material with a jointer plane, put the door back in the opening, and see how it fits. Maybe it takes you two or three trips to the bench to get it right. While I'm trimming the strike side, I also put a little bevel on the edge-not much-but it's good practice and makes the door less likely to bind in the opening.

The door fits the opening pretty well. The gap is the same at the top and between the two doors. All we have to do now is mark the locations for the hinges on the door and cut those mortises. There's probably a little more trimming that we'll do-when we put the hinges on and hang the door, it'll change the door location a tiny bit. Don't forget there's still a shim at the bottom of the door. When we take that out and put the string on the hinges, it will still need a tiny bit of trimming, but not too much.

Using the hinge location marks you made on the cabinet, mark the door for the hinge mortises. Square them off. Use a laminate trimmer with a straight gut to remove the material on the door so that the hinges will drop right in. Place an extra piece of scrap behind the door's edge to prevent blowout while you're mortising the hinges. The scrap gives the router a bigger place to sit so that it's less likely to tip.

The hinge leaf should fit nice and snug. I use a vix bit-a self-centering bit-that puts the hole for the hinge right dead center. I only do one at a time. That way if I have to adjust it later-and I might-I don't want to have to plug all the hinge holes.

Now that the door is hung on its hinges in the opening, the reveals are not right anymore. That's why you don't want to make it perfect before installing the hinges, because there will be more fitting to do. I'll pop off the door and look at the door mortises to make sure they're set correctly. Then I'll have to plane the door edges to correct the reveal and make it even all the way around. You can go back and forth from the bench to the door opening as much as you want-there's no magic, just patience.

nvman nvman writes: I wouldn't mind doing that for a special cabinet but a set of kitchen cabinets can have 30 or more doors and drawers. You could spend a whole week or more just fitting them. And if you have only evenings and weekends, you could spread that out over several weeks.

Chuck, you are amazing to be so meticulous. Kudos to you.

magicmartz magicmartz writes: Seems like a lot of cutting and r-ecutting to me. Perhaps buiding a door that is 1/4 to 1/8" too large is oversized a bit too much. But I suppose either way you wind up with a door that fits the opening well. Onward!

After reading a tip somewhere, I have begun using those little Formica samples you can get where you buy kitchen counters as spacers for the reveal around my doors. Works like a charm! Gap seems just right to me, and no more accidentally using my favorite shim as a paint stirrer:-)

bennyboy999 bennyboy999 writes: I would like you all to consider that trimming the door to fit, to keep in mind that the rails and stiles are diminished by the trimming. Trimming evenly is not difficult with some forethought. The uneven rails and stiles are something that you may or may not notice. It is nasty to notice after the cut is made.
