20…Let’s Build a Jewelry Box…Part 3

”Dreams are made possible if you try.” …Terry Fox

This episode is part of the Let’s Build Series

Woodworking Tips and Techniques:

1.) Using blue adhesive tape to aid the gluing process.
2.) Using Ulmia spring clamps for assembly and fitting of miter joints.
3.) Cutting perfect miter joints on the table saw using the Dedicated Miter Sled.

In Part 3 of this how to build a jewelry box video series we are back in the woodworking shop as we continue working on the Koa wood veneer jewelry box. We have previously fit the components together during a dry run so it is now time to apply yellow glue to the miter joints. First though, we need to tape the walls of the wooden box with blue tape. This will act as a hinge as it will allow us to spread the glue into the open miters and then swing the walls to close the joints. Also, when you only have two hands the blue tape greatly simplifies the task.

When the miter joints of the box are closed we can now clamp the corner woodworking joints tight with the Ulmia clamps. These pinch clamps are worth their weight in gold as they secure the miter joint while the adhesive sets. Notice how each miter joint has a spring clamp at the top and the bottom. This give equal pressure throughout the joint and assures alignment along the length of the joint. Note: We will make sure to check our wood project for square by measuring diagonally across the jewelry box and getting equal measurements.

When the wood glue is firming up we can apply blue adhesive tape next to the rabbets since we will be gluing the rabbets to receive the base. The application of the blue tape will help to contain the yellow glue and prevent it from reaching the surface of the wood veneers. We want keep the glue in the joints only. Any excess glue that reaches the veneer surface will create unnecessary work for us and can complicate the wood finish that will later be applied.

Since we have glued the rabbets we will continue by gluing the edges of the base and fitting the base to the rabbets of our woodworking project. When the veneered base is set in place we can proceed to securely clamp the wooden box. Note: Because our base is comprised of an MDF core with both sides veneered we can glue all four edges of the base because there is virtually no wood movement unlike a solid wood base.

After the glue has dried we take the jewelry box to our woodworking bench where we set up our bench dogs to the bench top adjacent to our woodworking vise. With our Koa veneered box we prepare to clean off the glue residue with our card scraper. When we are finished scraping the glue we then sand by hand to smooth the surface.

Our attention now turns to the box lid and how it will be housed in place. We are using solid Koa wood for the lid as well using Koa to cover the tops of the veneered walls. The tops of the veneered walls will have a slight overhang and will also be mitered at the corners. These tops will include rabbets to allow the lid to seat. We create the rabbets on the table saw using dado blades along with a sacrificial dado fence. In this section of the video we pay close attention to the safety accessories employed. Notice the handled push block used when cutting the rabbets. It controls the stock being cut and also keeps our hand away from the blades. When the rip cuts are made we use a splitter and a long push stick that keeps our hands at a safe distance as well as secures that the material is flat on the table saw top as the material is fed through the saw blade.

Our next job for this woodworking project is to cut the miters on the dedicated miter sled while ensuring a proper fit to the top of the veneered box. No tape measure or rule is needed as we mark everything based on its placement to the box. This eliminates any chance of error in measurement while creating a very accurate marking. With this procedure in place we will simply mark and cut as needed and then secure the miter joints with spring clamps. When all four miters are fit we will glue and clamp them.

The box lid is dimensioned for thickness by using two power tools; a bench top planer and an open drum sander. The planer does most of the work, however for the final dimensioning and smoothing the lid is run through the open drum sander. Woodworking Tip: Because the lid is of curly koa there is a chance for grain tearout so this is one important reason why the final dimensions for the lid take place on the open drum sander.
