Q: I would like to try biscuit joinery but I do not own a biscuit joiner. Is it feasible to use a router to make the slots?

A: A router with a 5/32-in. slot cutter will work fine for making an occasional biscuit joint. You can alter the slot depth to accommodate No. 0, No. 10 and No. 20 biscuits by using different router bits or by changing bearings.

Many manufacturers offer biscuit joining bits. Some use a single 5/32-in. slot cutter plus different sizes of bearings for different biscuit sizes. Others offer three separate bits for each biscuit. The MLCS system shown above uses three different bits. A specialized round biscuit fits the midsize bit without the need to elongate the slot. It’s perfect for joining face-frame stock and can be used on rails as narrow as 1-1/2 in.

To cut a biscuit slot with a router, you generally need to make the initial plunge cut and then move the router approximately 1/2 in.
