Biscuit joints can work well in face-frame joinery, but don't assume you can use a #20. You need a smaller biscuit so the joint won't show. Dowels are a decent alternative for joining face frame parts, but they can be tricky to align to get the faces perfectly flush. Pocket screws add lots of strength to a face frame joint. And unlike other types of screws, these are easily hidden on the inside face. If your wall cabinet is going to store books or dishes, you're going to need all the strength you can get to counteract gravity. That's one good reason to add a frame to an already strong case. The second reason is aesthetics. Sometimes a traditional cabinet you're building calls out for a face frame. Even if strength isn't a concern, the look of a face frame can dress up what some might call a plain piece of furniture. If you're adding a face frame for looks, then strength isn't your first concern and so the joinery used on the frame itself can be of many different styles. Face-frame Joints Face frames on cabinets are close cousins to frame-and-panel doors. Many of the same joinery options are available for face frames as are used in making doors. To determine what joint is best for the application, you need to look at the strength and appearance requirements. In some instances a butt joint is possible on a face frame. This would be one of those aesthetic situations where a case is already plenty strong on its own, but you want the look of a face frame. The frame is then simply glued or nailed to the case and the stiles (the vertical pieces) and rails (the horizontal pieces) are butted together. While this is fre- Through dovetails At left is a diagram of a hanging wall cabinet. When a case piece like this is hung on a wall, strength becomes an important factor. With no floor to support the weight, the joints have to be even more reliable. This piece uses strong joints in the box itself, with through-dovetails at the corners of the case. The solid wood back is rabbetted into the case, then fastened by nails. The face frame is assembled with mortise-and-tenon joints in the corners then glued to the box. The frame-to-case strength can be increased even more by pegging the frame in place. There is a lot of strength in this cabinet's joinery. popularwoodworking.com 33 |
