While there are several different ways to make a mortise, the only thing that will make ones that are high quality and professional looking are actual mortising machines. If you can’t get one, you could use one of the other methods, but you really want to try to use an actual machine.
This is especially true if you’re making a mortise on pieces that you’re selling to people. A great thing about these machines is that it pushes out the wood in one movement so the tenon will fit perfectly.
With that being said, there are a few things you want to look for when getting ready to purchase a machine.
For starters, you want to find a machine that has a good speed. Getting one that’s too slow will result in the wood not being pushed out thoroughly and cleanly and getting one too fast means the machine will be harder to control and can quickly ruin a piece.
Next, you want to find a machine that’s efficient. You want to be able to do what you need to quickly without having to go through a ton of steps. Finally, you want to make sure the machine is high quality.
You want something that will hold up to hard use and will make a perfect mortise every time. Below we’ve reviewed the top 10 best mortising machines on the market in 2018.
