Topic tags/keywords: breadboard tounge groove glue

Working on my first project with breadboards…..

My glued up top is 19” wide x 3/4” thick and I’m using a rabbet bit on the table router to put a 3/8” long x 1/4” thick tounge centered on the end grain.

On my bread boards, I need to cut a groove that is 1/4” wide (centered) by 3/8”+ deep. But I don’t want it to go all the way through on one end, so the toungue and groove joint is not visible from the front.

when I cut the groove in my bread boards….should I…

1. cut the toung on the panel end grain first and then cut the groove in the bread board with a stack dado on the
TS, using test cuts and shimming the dado stack to get a snug fit?

or …

2. cut the grove in the breadboard first with a 1/4” dia. bit on the router table and then sneak up on the tounge thickness by making test cuts and raising the router bit on the table router untill I get a snug finish.

or…

3. some other way?

and when i attach the bread boards, should I …

a. glue along the entire width

or …

b. only glue a percentage of the total width, with no glue at either end? And what % gets glue?

Thanks in advance for any help.

Do you mean like this? There is NO glue in the joint. Top is five boards, so there is a single screw into each board. I center the screw in the board. Width is about 5/8”, by about 3/8” thick tongue. Leaves the breadboard parts a might thin.

Seems to work alright, though. I usually run my tenon all the way through though, others tend to stop theirs a bit short of the ends. Trying to hide something, i guess….

thanks for responding and for the pics

I hadn’t ever heard of screwing the bread board to each board….

seems like it contradicts the intent of allowing movement with humidity changes.

or do you cut a slot in the end of the tounge?

Very little movement in about three inches of wood. I use a clamp to pull the ends in nice and tight. Screw hole in the bottom lip of the end piece is a bit oval, all except the center one. If you want, you can add a spot of glue. either in the middle inch or two, or, in the front inch or so. Glue will “lock” things in place. Screws will allow some movement. Screws are underneath, so, out of sight/out of mind.

I’m thinking that my tounge will need to be wider if I go the screw route….

any other bread board bakers want to chime in?

any comments on the sequence of events to get a snug fit?

I have seen them up to 3/4” wide. Some will “peg” it in place, with either the front or center peg fixed in place. Then, you slot the holes in the tongue so that the other pegs are aloowed to float. Center of top, or, front of the top, stays put, the rest will move as it wants to.

I use screws because they will lean a little in the hole as the top moves. I use the center of each board to lessen the amount each screw will need to move. Note; I added NO glue to this top. The whole bread board is left to it’s own devices. It may be old, dried out Beech, but it will still move a bit.
