I was debating whether or not to invest $40 for a drawer locking router bit. I decided to take the plunge and see if it really does do a good job, so I ordered on from Infinity Tools on Thursday. It was in the mailbox on Saturday. FWIW, Infinity gives a $3 discount for web orders.
The instructions are simple on how to do the setup. For some reason though, it took a few tries for me to get the fence set properly to do drawer sides. I finally took a break, looked at the picture and DUH, it was really that simple.
I cut 20 pieces of wood. Four to house the drawers, then 8 deep and 8 shallow for the two sizes of drawers I'm going to make. I did all of the fronts and back, then the two sized of the cabinet. Moved the fence and did the rest of them. It was quick and easy. Best part though, was assembly. The drawers lined up square. It is, by far, the most accurate setup for drawers I've ever done.
Only thing I'd do different is to leave the shallow drawer parts wider to make it easier to push through against the fence. Rip them to size later. Though called a drawer locking bit, it can be used most any time you want to join wood at right angles.
