You can easily turn your corner storage shelf into a nice cabinet with a glass lined or decorated door with very little effort. This can keep dust off of your items on the shelves and make them hidden from view or displayed with pride depending on the door you want to install. There is only a slight variance between the two, yet making a glass door will be more work and more time consuming to get the desired look once you are done. You will first want to take a total measurement for the height and width of your corner cupboard so that the door will properly cover its face.
Step 1 - Cut or Frame your Door
Once you have the wood needed to make the doors for the corner storage shelf, cut your sheet to the height and width needed for the job. It is best to have 1/2 inch to 1 inch overlap on all sides of the door running onto the face of the cabinet. use your Dremel tool or other edging tool to add a fancy edge to the door for character. There are a number of bits that can be purchased to be used with a Dremel tool to get a beveled edge on your door panel. Be sure to clamp the piece down while working to keep it from moving during your cuts.
Step 2 - Make a Hole for your Glass Insert
if you want glass in the front of your corner storage shelf door, take the inside measurement of your shelf area. You will want to make sure you have 1 inch to 2 inches of frame from the edges on all sides to the inside cut. Turn your work over and draw out the area to be removed, remember to leave a space to make a ledge for your glass at least 1/2 to 1/4 inch all around your cut, which will be what your glass will press against. Use a bit to start a pilot hole on your center cut, and use your Dremel tool to cut out the hole in the center. Use the edging bit to put a flat ledge all the way around the inside of your cut to hold the glass.
Step 3 - Finishing the Piece
Once a hole in the door is cut for the glass, and it is sized to cover your corner storage shelf, you can apply stain or paint to match your cabinet and the rest of the room. Once it has dried, insert your glass through the back of your door, and then screw in the holders that will pin the glass into place. You can now mount the door onto the cabinet with your hinges and attach your handle or latch as well. Once you are finished with this, open and close the door to check its functionality.
