Plan for ripping the lumber |
The lumber, cut to the desired widths |
Cutting the Rabbet |
Next, I cut the rabbet into the back of the wood (the deep notch in the bottom right of the diagram at the top of this page) using the table saw. First, I marked the dimensions of the cut on the end of one of the pieces. |
Marking the wood for the rabbet cuts |
|
|
I set my table saw blade depth at 3/4 of an inch, and set the fence at 1/2 an inch. To make sure the cut is accurate, I lined up the wood with the blade (with the saw off) to see where the teeth would hit, in relation to the lines I marked on the end of the wood. In this case, you want the blade to cut on the scrap side of your lines, as shown in this picture (note that in the picture, I’m just checking the width. I haven’t set the blade depth yet). |
With the blade set, I ran both pieces across the blade lengthwise. This cut a narrow channel in the wood.
Cutting the rabbet, step 1 |
To complete the rabbet, set the saw fence at 3/4 of an inch, and the blade depth to 1/2 an inch, and run the pieces along the saw again. This will complete the rabbet. This doesn’t have to be exactly dead-on, since this is just the channel in the back of the frame that will hold the glass, art, matting, and backing. This will not actually be visible, once the frame is complete. Here’s what my wood looked like after the second rabbet cut:
Cutting the rabbet, step 2 |
Note: Pay attention to the thickness of the saw blade, and make sure that you’re cutting inside your lines. That is, that the blade is cutting on the scrap side of the line. When you’re working with pieces this small, the thickness of the saw blade can actually affect your measurements and throw off the end result. |
Routing a Decoration |
Once the rabbet was finished, I routed the decorative ledge into the face of the frame. I inserted a rabbet bit into my table router, set the depth at 1/8 of an inch, and adjusted the fence so that when I ran the wood along it, the router bit would cut into just the first 3/16 of an inch or so of the wood. This is best done in several passes. After each pass, I adjusted the fence a bit, and repeated it, until the ledge was eventually 1/2 an inch wide. |
|
Rounding the Edges |
The last step was to round the edge of the wood. I installed a 1/4 inch rounding bit in my router and set the depth at about 1/8 of an inch. I didn’t use the router’s fence for this step, since my bit is a pilot bit, meaning it has a roller bearing on the tip that you press the wood against as you slide it along the bit. But you need to keep a firm grip on the wood, and use your router’s starting pin to get started. |
Rounding the edge of the frame |
|
As with cutting the face ledge, I started shallow and made several passes, gradually raising the bit up out of the table a little bit each pass. This allowed me to just take a little wood off at a time, giving a nice, smooth rounded edge. |
Rounding the edge of the frame |
Give the pieces a light sanding with some 120 grit paper, then 220 grit paper to smooth out any rough spots. |
