Hello All….Breadboard joint…is this correct? I am making cutting boards and want to put a breadboard joint (tongue and groove) on the ends. The boards are just over an inch thick….should I use a dado for the tongue and groove, or is there a better method? Thanks for any info…….Don

tongue and groove is fine. You may want to opt for a mortise and tenon....as tongue and grooves normally are through joints. If you go with a through joint, you can "dress up" the show part by making that a dovetail with a standarad tongue and groove in the unseen part of the joint - this would be a joint just like that commonly used for solid wood casework. Remember to only glue the front few inches and to pin the remainder of the joint.....
Thank you Tim for the ideas....I like it but I am a bit confused on "glue up only the from few inches and pin the rest". Could you elaborate? Thanks again.....Don
wrong word. how about:
Glue up only the first few inches. Pin the middle and back.....in a manner that allows the pins to move.
Given decent lumber, breadboard ends are decorative much more than functional.Tim
DKF,
This is one of those projects where going to the library and getting a "how to" book would make it a lot more enjoyable for you. Putting a breadboard end on a cutting board means your setting up a cross grain situation and you have to allow for expansion and contraction of the wood in the field. The terminology might be confusing, a dado is a trench cut cross grain...a grove is a trench cut with the grain..why they have different names ...I don't know. You can have a tongue go the whole length....or end short of both ends so its hidden in the grove.....you can also cut away substantial parts of the tongue so that it is like a mortice and tenon. No matter what you do You need to attach it to the field and allow the field t move.....so you only put glue in the middle....and if you use pegs...put no glue in the other pegs..but enlarge the hole on the tongue so the filed can slip by....good luck
Thanks everybody.........gonna glue and pin.....great advice!......Don
Tongue and groove router bits can make excellent breadboard joints and will do stopped cuts that are not exposed. Most manufacturers offer a set but not many will work with material over 3/4" thick. The 99-036 set that we offer is ideal in that it is adjustable, it will handle your stock thickness and the tongue cutter has opposing shear angles to prevent tearout on the end grain.
