It could be said that miter joints are definitely one of the most common joints in woodworking or carpentry. This is a joint that we are taught early on in our apprenticeships because we will be cutting miters throughout our entire career. As an apprentice it sounds simple enough to just cut a left 45 and a right 45 and glue then together to form a 90. If it were so simple then why are there open miter joints? Let’s take a look at how we can make perfect miter joints.

not a bad article Bob
but I wuold prefer if you also had talked about why its not always stay as a perfect miterjoint
over time nomatter how carefull you have been when you made them
and the wider your joint is , its easyer to see that it ain´t stay stabil and being the perfect joint
over time , becourse of the build in weeksness there is,
and I ´m not talking about glueing endgrain to endgrain, I´m talking about scrincages and contraction
in both dimension and the different in length between the outside and inside corner

hope my point get thrugh on what I am trying to say

best thoughts

Dennis…My goal in writing this article is to focus on the skills and techniques of the woodworker. The article is about the execution of how the joint is cut, fit, and glued together to make a good fitting joint.

What you are referring to is the stability of the joint over time after it has been fit. Sometimes joints will open due to seasonal changes and changes in humidity. That is another worthwhile topic in and of itself. You make a very good observation because a woodworker can make what appears to be a tight fitting joint and then later it opens up.

However, at this time my intent is to focus on skills and techniques to make a quality miter joint.
Thanks for reading the article and bringing up a very good and important point!
