The rabbet joint is a very similar woodwork joint to the butt joint but the big difference between the two is that one of the ends of the timber has a groove cut out of it to create much better holding strength.
Even with the extra strength the joint is still relatively easy to construct and its appearance is also more appealing compared to a regular butt joint making it a better joint for carpentry or cabinet making.
If more strength is still required you can also add nails, screws and dowel to the joint just like you would on a butt joint but no timber blocks should be needed in the corner because the rabbet joint already has a large surface for adhesives to be applied.
Step 1: The first thing you do when making a rabbet joint is measure and cut two pieces of timber to the size or sizes you need.
Step 2: Make sure the ends of your timber are flush then get the piece you want your rabbet in and mark out the width of the joint the same as the thickness of your second piece of timber. Now mark another line on your first piece of timber about half its depth and mark around each side of the timber.
Step 3: You should now have connecting lines so make sure they are accurate before cutting. Use either a tenon saw or a band saw and cut along the lines to make your rabbet.
Step 4: You can use a chisel to clean out your rabbet if the timber you insert does not sit flat in the joint.
Step 5: If your joint is flush and square secure it together with adhesive. Nails or screws can be added to increase strength or dowel can also be used but the holes must be accurately drilled before you start step 5.
