Breadboard ends on fairly thin table top
Hi everyone,
Happy 2015! Well, I'm working on a Jarrah Side table project at the moment, and have a bit of a question regarding the table top i wanted to throw out to the crew.
My table top is from 19mm thick Jarrah, and for both aesthetic and functional purposes ( i need to increase the length of the table and already have a panel made that is 82cm long. It needs to be 99cm for the space i want to put it ). So i figures putting some 8.5cm wide breadboard ends on would be nice.
My query is, what would be the best way to do this given the thickness of the table top which is 19mm. My first thought was sliding dovetail, but my 1/2" dovetail router bit really doesn't leave much room on the edges of the stock, and is prone to tearing out the edges on the test pieces I've tried, so i'm loathed to put my workpiece though that process. I'm also thinking that as mortise & Tenon joint might make it too thin and be prone to snapping and be a real weak point?
My next though was to use dowels, and just make the slots in the table top a bit elongated to allow for movement. Is that an acceptable solution? Especially if the dowels run quite deep into the breadboard end, and fairly deep into the table top?
Keen to hear how others might tackle this?
Cheers
Seb

I've never used breadboard ends so I'm also interested in learning how to construct them.

I've never done them, but I've seen examples using floating tenons. Rout out mortices in the top and ends, then round over the edges of some scrap for the tenons. As you've said, leave room for expansion/contraction. I'll see if I can dig out an article about them for you.

You will need to be adding close to 10cm at each end which is not overly wide, if you just cut a shallow tongue and groove to mate up the ends to the table top. You could then mortice into each piece and glue in longer tenons to provide some lateral strength if there is much chance of weight loading the ends so the joint looks more like the pics here.

This last option sounds like a good solution. I think I'll go with something along those lines!

Hi Sebastiaan, Here's a link to a video on how to cut the joints fairly quickly with a handheld router. Probably best to fit the extension tenon pieces into the ends first, after squaring the top and marking the shoulder lines..

Here is an article I wrote, for use of handtools, on making breadboard ends ..

Below, laying out the mortices ...

The breadboard ends used in this lap desk are in sections that are just 3/8" thick - the tenons and mortices are 1/8" thick, and chopped with a 1/8" mortice chisel ..

Many thanks Derek.
Your final product in that article is very much what I'm aiming for!
I don't have the handtools to do this, but after buggering around with setting up my router into the table, huffing and puffing because I can't get my slot cutter bit high enough above the table etc...........I am starting to think that power tools aren't the be all and end all when it comes to time saving!
I'm hoping to get this done by the end of the week, so if i manage that I'll put up some photos ( this is my holiday project! ).
Cheers
Seb

Hi Seb
If it is just a groove that stalls you, you can use a tablesaw instead of a router. You could deepen this progressively. The groove could act as a guide to set up a straight router bit, with the mortices routed from above and running on registration blocks clamped to the side.
You can use the tablesaw for the tenon/tongue and well.
If this is not clear, then yell out for instructions.

The quickest way is to use a biscuit joiner and rather than just a row of biscuits in a line , do one half 5 mm down from the top to the top of the biscuit and the other half 5mm up from the bottom .
Or , a 6.5mm slot 14mm deep each side and glue in a cross grained tongue or same grain direction as the top wood , then glue on the BBE .
