Using a Router for Wood Inlay

Using a Router to Inlay a Compass Rose

 

The woodworker is using a router in this woodworking article to create a recess in mahogany. This recess will house a compass rose veneer that was previously sliced on the band saw. Now, a Dewalt DWP611PK compact plunge router with a 1/4 inch straight router bit is used to cut a recess to house the veneer.

 

The techniques demonstrated by the woodworker in this article are basically just for practice. He is simply testing to develop a strategy for when it becomes time to actually inlay the compass rose veneer. Practicing woodworking in the shop is a great idea. It’s a good way to develop confidence in one’s skills. We all know that it is better to make a mistake while practicing rather than to make an error on the actual woodworking project

 

Laying Out the Compass Rose

 

Compass Rose - Bandsaw Resawing - Using a RouterThe first step for the woodworker is to outline the compass rose on the mahogany. This is simply done by tracing a pencil line around the compass rose veneer. Then the layout lines are cut by using the straight edge from a combination square and scoring the lines with a sharp utility knife. The cut lines are then penciled in for better visibility.

 

Using a Router to Make the Plunge Cut

 

Using a Router for Wood Inlay
When using a router to make a plunge cut for wood inlay,  it is necessary to “zero in” the router bit. What this means is that the router is adjusted so that the bottom of the router bit is at the same level as the router’s base. Next, the router bit can be adjusted for the depth of the plunge cut. Since the thickness of the compass rose is 3/32″, the bit will need to make a plunge cut of 1/16”.  This will allow the compass rose to extend above the surface of the mahogany by 1/32″. This is an ideal amount for scraping and then sanding so that both surfaces can become level with one another.

 

A Compact Plunge Router with LED Lights

 

When using a router to freehand the pattern, it is critically important that the woodworker takes his or her time. We want to make sure that the router bit maintains the cut within the scored lines. One beautiful feature of this DeWalt plunge router is that it has LED lights to illuminate the cutting area. This makes life so much more easier and that much more enjoyable for the woodworker.

 

Routing Closer to the Lines

 

Using a Rotory Tool for Wood InlayAfter the woodworker is finished using the compact router in this demonstration, he then uses a Foredom rotory tool with a 1/8″ bit to rout closer to the lines. As you can see, the rotory tool is in a shop-made wooden base. Afterwards, hand tool skills are required as chisels and a mallet are used for the final cutting of the recess.

The compass rose wood inlay veneer is now fit into the mahogany. The next step is to carefully glue this veneer into the recess.

Finish Work Methods for an Inlaid Picture Frame

Finish Work Methods for Lasting Beauty

 

Finish Work Methods Include Surface Preparation

 

Completed Cosmati Picture Frame - Finish Work MethodsFinish work methods can make all the difference in a woodworker’s project. One of the major challenges for the beginning woodworker, intermediate woodworker, or even an experienced longtime woodworker can be the ability to achieve a satisfactory wood finish. Surface preparation is a key ingredient to achieving the desired results. In this woodworking article we will focus on these important woodworking skills. These finish work methods include the use of a card scraper and also the use of sandpaper with a sanding block.

 

The Value of Using a Card Scraper

 

Cosmati Picture Frame - Finish Work Methods - Card ScraperWhy include the card scraper in the finish work methods? The card scraper gives the woodworker a controlled way of leveling the surface of his woodworking project. In the woodworking video, the woodworker uses the card scraper to level the decorative wood inlay banding to the surface of the picture frame. Not only is the woodworker taking thin shavings off of the banding, he is also cleaning up all the glue lines and any excess glue that may be on the surface. It is critically important to remove this dried glue prior to applying the finish. If not removed, the glue will stick out like a sore thumb once the chosen finish is applied. So, it is imperative that we take care of that now before it becomes an issue.

 

Control the Wood Being Removed

 

Another important reason the card scraper is included in these finish work methods is because the decorative wood inlay banding is of only 3/32″ thick and the banding is inlaid and glued into a shallow depth of a 1/16″ dado. The card scraper allows the woodworker to remove thin shavings of wood at this time while eliminating the need for any heavy sanding. In this way the woodworker can carefully control the amount of material being removed. We definitely want to make sure that the inlay banding is not sanded through.

 

Why Sand with a Sanding Block? 

 

Cosmati Picture Frame - Finish Work Methods Sandpaper is used with a sanding block. This woodworking technique allows for the woodworker to comfortably grip the sandpaper. This method also provides the woodworker with a great means for applying an even pressure to the picture frame surface. Keep in mind that we are looking for a smooth, flat surface for our woodworking project.  Depending on how well the work is performed with the card scraper and the type of wood being used for the project, it is likely that the initial sanding can begin with 100 to 200 grit sandpaper. In the case of this picture frame, the woodworker continued to prepare the wood surface up to 400 grit sandpaper.

 

How to Check for Glue Stain

 

A portion of the finish work methods includes applying a small amount of paint thinner to a rag and then applying it to the picture frame. Why is this an important element of the finish work methods? There are two parts to this answer. The wiping of the woodworking project with paint thinner helps to clean up any sawdust that may remain from the sanding. This cleaning technique will also show us any glue that may may be left on the surface of our project. If we see any glue stain showing at this time, we still have some more work to do before we apply the wood finish. If any glue stain remains, we need to remove it with further sanding.

 

Sanding Sealer, Cherry Wood, and Blotching

 

These finish work methods lead us up to the important moment of applying the finish. In the case of the woodworker’s picture frame, he chose to apply a coat of sanding sealer to the cherry picture frame. Cherry is prone to blotching and the sealer will help to remedy this issue.

 

Applying the Lacquer

 

Cosmati Picture frame 086After the sanding sealer has been applied and given time to adequately dry, it is time to perform a light sanding. This sanding will help by giving the surface some “tooth.” In other words, when the lacquer is sprayed onto the freshly sanded surface, the lacquer will have a good surface to adhere to. (Be sure to remove any and all sanding dust prior to applying the lacquer.) The woodworker can then proceed to build up layers of lacquer to achieve a desirable wood finish for his or her woodworking project.
