How to Make Bridle Joints

The thickness will be the same as the tenons thickness and you can use it again as a template if you need to but remember to measure the space on each side of the mortise to ensure it is centre.

Step4: Now cut the mortise and once again there are two methods the first involves a mallet and chisel. If you use the first method you need to put some timber in a vice to rest your timber against and then you clamp the two bits of timber together to hold them steady.

Now you get your chisel and hammer it straight into the wood with the mallet. Apply some pressure away from the chisel bevel and repeat this on the other side of the mortise to create a V shape.

Work from the centre to the outside of the mortise and be patient meaning do not remove too much timber at once but also remember to cut the mortise the entire depth of the wood to house the tenon.

The second method of cutting a mortise involves the mortising machine and what you must do is set the width and depth before you use it. Once they are set simply drill into your timber bit by bit to remove the excess wood.

This method is also the faster more accurate one but remember not to drill too much at once and make sure the gap in the drill bit is facing the empty space of the mortise so the excess timber can escape when it is removed.

Step5: After you have completed the mortise and tenon check to see if they interlock neatly. If your tenon won’t fit you can shave a minimal amount of timber off with the band saw but do it to both sides.

Step6: Once you are happy with the joint and it fits flush and neat you can now bond it together with clamps and an adhesive.
