attaching breadboards

[clydeb]

Questions for the experts, I'm building a large conference table  4 ft wide in middle and two sections of 7ft,  total length 14 feet. Tapering to 40 inches on each end (Boat style)  Made from inch and half cherry.  The customers (law firm) asked if I would wrap the whole table in contrasting hard maple about 3/4 inch thick.  Question is how to attach the maple on the ends.  I though about using my domino cutter but thought about the whole wood movement senerio. With maple only 3/4 of an inch thick I dont think a tenon arrangement would work.  Maybe oversize pocket holes for pocket screws???? Any help would be appreciated  Thank You

I have not tried it but there is this on YouTube breadboard ends with a domino

I would use a 3/4" bearing guided rabbeting bit to route a tiny rebate and veneer it. Then use veneer to do the edge as well. You wouldn't have any wood movement problems but it would look like a 3/4" solid piece of maple.

Could you expound some on your idea please. Thanks

I used the [member=41090]justaguy[/member] method above for a dining room table, about 38" wide, and which has shown some movement without developing any cracks or problems. It's been about 3 years and so far so good. Located in San Diego so no extremes of weather, but previously without breadboard ends it was a problem...

I've done countless breadboard table tops and always use the widest setting into all the top and middle end board and make my own tenons using the same species timber, then manually move the domino to achieve the wider mortises on the rest of the breadboard end.

I also glue the middle third of the breadboard to the table as minimal contraction/expansion will occur.
The one thing he didn't show was to give the end of the table and length of the breadboard a slight arris because their will be natural movement and if it's flush then a glueline will occur and it looks and feels terrible.

Are we talking only a 3/4" wide border? Maybe I got it wrong. I dont really consider 3/4" a bread board, is it? It's more like a border.

IMHO if its truly only a 3/4" border of contrasting wood around the edge I would just glue it up that way from the start(1.5"x3/4" thick Maple glued to the 1.5" cherry), not attach it like a breadboard at all.

Now a 4" breadboard, that's a different animal.

This is essentially the same method on the UTube video posted here by [member=41090]justaguy[/member] .
