They make many add on's for the Dremel,it should do the trick for you.
It's small and you can get router bits (1/8" shank) to make the slot.
Or you can make a (point jig) to keep the bit in the right place.
Small block of hard wood that holds the Dremel and comes to a round point on one end of the jig,the pin rubs on the edge of the chair and the block to keep the bit from going to deep.
Looks like a cam lobe with a 3/4" or 1" hole with a set screw to hold it in the Dremel tool.
Below you will see some snapshots of the one I made today just for kicks, note the two off sets (5/8" and 1" ) on this one and the two pins,this one is walnut ,1 7/8" tall with a 3/4" hole for the Dremel and 1/4-28 x 1/4" allen set screws to hold it in place,one on ea. end, 1/4" dowels for the guide pins, not glued in just in case you need to used longer ones.
