Mortise And Tenon Bed Rails

Mortise and tenon bed rails.

April 12 2017. With the tenon partially seated in the mortise there should be enough friction that if you lift the tenoned workpiece the mating piece comes with it. Regardless of which one you choose to use start by drilling the couterbore and clearance hole in the leg both at the drill press then put the leg on the bed rail tenon and use a handheld drill to make the bed bolt hole in the bed rail. Right now most joints will be mortise and tenon.

The posts can also be cut to size and shaped and the live edges treated. To join parts of equal thickness cut both the mortises. The top and bottom tabs provide lateral rigidity and prevent rotation while the heavy corner gussets maintain a perfect 90 angle the m8 5 16 connecting bolt is held captive in the bed rail bracket so you never have to worry about losing it. The remaining two thirds of the rail the tenon shoulders help to counteract lateral forces that might tweak the tenon from the mortise contributing to its strength.

These handy implements work to trim the end of your log rails allowing them to be inserted into other logs to create the base structure of your furniture project. The leg acts as a guide to keep the hole as perpendicular to the rail s end as possible. The haunch the cut away part of a sash corner joint that prevents the tenon coming loose is one third the length of the tenon and one sixth of the width of the tenon in its depth. Complete the tenon by standing the rail on edge and cutting the top and bottom shoulders.

Now we re onto the last bit of joinery in the project. Ellis s rule says that your tenon should be 3 wide. You want to cut a 1 4 thick tenon on a 6 wide rail. I d like to be able to take the loft down to parts and the simplest thing to do would be to disassemble it at the m t joints.

Through mortise and tenon joints typically go together one of the two ways shown above either both parts are the same thickness a 3 4 rail mating a 3 4 stile for example or the tenon fits into a mortised part of greater thickness such as a 3 4 thick table apron against a 1 1 2 square leg. Table leg to rail joint mortise tenon the most common way to join table legs to rails is the mortise and tenon joint specifically the stub haunched mo. Rails and posts jr s bed part 4. Includes enough brackets for one bed.

But a 3 wide tenon is greater than 1 1 2 which is six times the tenon thickness. If that tenon s width would be greater than six times its thickness then you should split it into two or more tenons. I m designing a loft bed here s a rough picture without the cross supports and other details. This joint will consist of a stub mortise and tenon which will be held in by a bolt which i will add later.
