FINGER OR COMB JOINT

V. Ryan © 2002-2004

This a good example of a ‘finger’ or ‘comb’ joint. It is ideal for box constructions and is suitable for use with natural woods such as pine and mahogany or even manmade boards such as plywood and MDF. The joint is strong especially when used with a good quality glue such as PVA (woodworkers adhesive) or cascamite.

   

If the joint is cut accurately the ‘fingers should fit together without any gaps and the glue ensures that they are virtually indestructible. They are used for a wide range of products including jewellery boxes, cabinet construction, kitchen cupboards and many others. (Example below - a box containing an electronic game for a young child - notice the finger joints)

Here we see a finger joint before it is glued together. The fingers are lined up with each other and they should slide together, rather like the fingers on you right and left hand when you interlock them. Try forcing you hands apart when they are interlocked - you will find this difficult to do.
