A wooden mallet is a good tool to have in the shop. Usually on your projects you don’t want to beat it with a steel headed hammer. You also want to make sure that when you use something to force one joint into another, or put things together (not talking about using fastners such as nails) that you want a wider head. And again, not a steel one that will leave an indentation in the project.
So the mallet is the tool of choice in this area. There are many different ways to build your own mallet, and even this tool in the video can be modified in order to fit your likes. I personally like a few different size heads on my mallets, but one thing that you really need to make sure of is that the head of the mallet is pretty solid.
In the video, the wood worker uses maple for the head. It is a great stock to use because of how hard it is – and durable. It won’t start to crack or break up after a few blows and will last. So check it out and make one for yourself using the video:
