Using a Commercial Dovetail Jig

dovetailDovetails have long been associated with quality woodworking and quality furniture. Dovetails look great and add a unique detail that shows the craftsmanship of the woodworker. Traditionally, dovetails were cut by hand using a back saw and a chisel, and in some cases a coping saw top help cut out the unused pieces. If you are a dedicated hand tool craftsman and or are a commercial woodworker and you can take the time to practice hand cutting dovetails, it is possible to get some amazingly accurate and beautiful results. If you are a some-times, novice or infrequent woodworker, cutting hand dovetails is something you may do very seldom so getting nice cut dovetails is much harder to do, and that is why a number of companies have developed and sell, jigs that can help those "infrequent" woodworkers in making quality dovetails.

Many of the commercial dovetail jigs are similar in their designs and in the way they operate. In most cases they will use a router with a dovetail bit fitted to it, and often these bits are included with the jig. Another thing in common with most of the commercial jigs is that they will only make what are called 1/2 blind dovetails out of the box, if you want to make Through dovetails you may need to purchase additional pieces for your jig. To see pictures of the difference between Through and 1/2 blind dovetails, see pictures further in the article.

Box Joint Jig - Operational Details

box_joint_thmJudging by the number of questions I received about making the box joint jig, it is evident that I didn't cover off with enough detail exactly now the "indexing" or "finger alignment" worked, so this video is to make up that shortfall. When you are making Lynn Sabin box joint jig, one of the key components is the Readi-Rod (also known as threaded rod, Redi Rod, Ready Rod and Thready Rod). The rod basically has three components, the length of the rod, the diameter of the rod and the number of threads per inch that are carved into the rod. Of Course the length is important as it needs to be the full length of your jig, the diameter is not so important but I found 3/8" to be a good weight to work with, and the final Very important component, the threads per inch ... should be 16 threads per inch. There are many other options of threads per inch and you can decide if another is best for you, but for most woodworkers 16 will be the best and here's how it works.

 

Comparing Box Joint Jigs

box jointOne of the most recognizeable joints in woodworking is the dovetail joint. It has been around for centuries and is always associated with quality. In the past century one of the main purposes of dovetail joints is in making drawers, which is a real pity because dovetail joints are such a pretty joint they should really by "seen" more often. What many woodworkers don't realize is that as popular as dovetail joints are, they are often confused with another joint called "box joint", which is similar in design and look, but box joints have square pins and tails compared to dovetail which have angled pins and tails.

When comparing the two joints, the dovetail joint is easily the prettiest of the two but slighly more difficult to make. The dovetail joint It appears to take more time to make and just looks better. Among woodworkers, anyone who can actually hand-cut high quality dovetails are often held in high regard. One of the best people for hand cutting dovetail joints that I have had the pleasure of meeting and working in association with at woodworking shows is Rob Cosman. I can't imagine how many dovetail joints Rob must have cut in his lifetime, but the quality of his cuts is evidence that practice make perfect. Check out Rob's website for more information on dovetail joints at www.robcosman.com.

Now, back to the topic of box joints, and comparing the jigs and how to make them.

What most woodworkers don't realize is the most people who know a bit about fine furniture will call box joints dovetail joints. There is really only a small portion of the population that really know the difference. It's almost like what a woodworker told me once, "if you want to impress another woodworker, make a dovetail joint, if you want to impress the rest of the population, a box joint will work just fine".  To back up his claim, I told him that I had been in a number of situations where people have called box joints dovetail joints, and he agreed and confirmed that  only a very few, knowledgeable furniture experts have been able to identify the difference.

So, what are some of the best ways to make these joints, well, read on and we will show talk about them.
