biscuits or dados for building cabinets?
I will be building an entertainment center made up of a 4’ center unit
and two 2’ flanking units all 8’ high. When I build the cabinets are biscuits or dados the preferred method of joining the top, middle and bottom pieces to the sides? Do biscuits perform well when joining the stiles and rails of the doors? Thanks for the help Keith |

The answer is:
Depends. I used a rabbet on the top, and dadoes for the shelf and bottom, with a rabbet for the back. Wish I'da gone with sliding dovetails for the shelf and bottom, just for my personal edification. I used a frame and panel bit set for the doors, and the rails and stiles fit in the pre-defined grooves created from the bits. You can use biscuits for the joints if they are "plain". You can cut matching profiles, use splines, make some of those cool "butterfly" joints, use other joinery methods, whatever you want to do. |

Thanks for the help Keith I have built dozens of library shelves for the local county library system and built a few sorting shelves for the post office..and a lot of school shelves. I love biscuits. I can certainly vouch for their strength and reliabilty, not to mention the ease of fabrication. That said, I understand why people like rabbets and dadoes, makes it feel more like woodworking. My cookies are stronger and look the same. |

Do biscuits perform well when joining the stiles and rails of the doors? More than one way to skin a cat. Dados will be strongest; but they are also the most work, especially with a piece as large as yours, and require the most care to make and assemble. A nearly correct dado is simply wrong. Biscuits are much easier, and when nearly correct are just a little wrong. I recently did a large piece with biscuits for allignment and pocket screws since I didn't have enough big clamps to claim it properly. They do add some redundant strength. It is 4' high and 5' wide; I bet you could walk on it without problems. (I just threw out the first thing I made; a TV stand made out of scrap plywood. Just to see how sturdy it was, I put 150lb of chain on top and hit it sideways with a sledgehammer. It took 10 hits before breaking, and never actually collapsed. Nailed dados.) You're in Rochester? It is actually supposed to be dry starting tomorrow; maybe I can get my lawn cut. |

When I build the cabinets are biscuits or dados the preferred method of joining the top, middle and bottom pieces to the sides? What kind of wood? If your cabinet sides are wood/woodpanels, the traditionally preferred method is dovetails to attach the top and bottom to the sides. If plywood, biscuits will work fine for either, although I usually prefer dadoes for any fixed shelves/dividers, and will even add screws to resist racking. Sliding dovetails look nice and do seem to resist racking better for dividers/fixed shelves, IME. Do biscuits perform well when joining the stiles and rails of the doors? I much prefer mortise and tenon, stick and cope for doors, or pocket hole joinery for any rails and stiles. An alternative method, IMO, for an _easy_ to make door for modern entertainment centers, uses a good cabinet grade plywood with at least 1" wide (the wider the better), mitered edging applied to the plywood using biscuits. An example of the latter: http://e-woodshop.net/images/plywooddoor1.jpg -- www.e-woodshop.net Last update: 10/22/05 |

Bicuits and pocket hole screws are a excellent joinery method.
It will also go a LOT quicker. Dados are nice but real time killers and a pain in the wazoo to get "perfect".

biscuits or dados for building cabinets?
for casework, i tend to use dados and rabbets for alignment, then glue
and (if necessary) screws from the outside (assuming it's a hidden surface). i stopped using pocket screws for case work for two reasons - cost was starting to add up, and the time it took to drill all of the holes was adding up. i don't have a pocket hole machine, so the time started becoming an issue. the type of screws is important. i buy 1 1/4" screws, self tapping, self drilling heads - they really don't require predrilling. i buy them by the 1000s (Custom Service Hardware, FWIW). they do a great job of snugging up a 90 degree case joint, when driven through rabbet lip into edge of mating material (attaching a top to a side, side with rabbet). i rabbet all four parts and tightly fit the back (always use 1/2" backs) and the case is incredibly strong. all rough edges are hidden by dados and rabbets. the face frame gets attached with biscuits. the dado approach works well as it avoids a butt joint and therefore blends the plywood veneer well. but, all approaches are fine - choose the one you're comfortable with and go for it. fwiw, i use biscuits all over the place, but not for plywood case construction - just don't see the need. i'm sure it would be a fine method. i used to think that biscuits don't add any strength - now i certainly think otherwise. get a good #20 biscuit (lamello) and try to break it in shear - they are strong. if you have 4 or 5 on a joint, they are very strong. for casework, a good option... just not my method of choice. good luck, ---- dz Keith Boeheim wrote: I will be building an entertainment center made up of a 4’ center unit and two 2’ flanking units all 8’ high.

I'd hate to see a heavy TV or home theater receiver sitting on biscuits. I'd hate it more to not seeing it on biscuits some morning. My TV weighs 185 pounds. I'd go for the dado or rabbet. Something to keep in mind when you design it is weight distribution. On the big screen CRT models, most of the weight is up front with the screen so consider the balance to avoid tipping. -- Ed http://pages.cthome.net/edhome/ |
