How to groove the back of a curved drawer front
I currently making a bow front jewelry cabinet for me wife. I have always wanted to make a bow front cabinet and everything started to fall into place for this to be the one. Great wood (Madrone), a great shop (here at FWW) to use, and some great woodworkers (fellow editors) to help if I got stuck anywhere. As it turned out, things haven’t been to tough so far, but I was stumped a bit about how to groove the curved backs of the drawer fronts. Normally, I groove drawer parts either with a dado blade at the tablesaw or a straight bit in the router table. Neither method works with a concave drawer back. I ran through many possible ways to do it, and checked with some of other editors. No matter what I or they came up with, I kept coming back to my initial thought. So I made a fence for my router table that is curved to match the radius of the inside of the drawer fronts. Then I put a slot cutting bit in my router and went to town. It worked great for the drawer fronts.
One tricky part was cutting the grooves in the drawer sides. They’re straight and I was hesitant to use the curved fence to cut the grooves, because only a small part of the side would be against the fence at any time. But it’s always best to cut the groove in the front and the sides with the same machine and the same setup. So I simple clamped a narrow board with a rounded end opposite the slot cutting bit. The rounding end forced the sides against the fence at just the right place. And all the grooves came out perfect.
Under construction. I'm in the process of making this cabinet for my wife. Cutting the grooves in the back of the drawer fronts was tricky. (The drawers and doors still need to be veneered.)
Simple solution. This fence is curved to match the inside curve of the drawer fronts. The slotting bit sticks out 1/8 in. and cuts a 1/8 in. deep groove as the fronts slide over the curve.
