Buy table legs, a strip of 2"x1/4", and the threaded inserts from your local hardware store. Buy the cheap 2"x3" photo frames from Wal-Mart.
Chop off the bolt from the table leg and round off with a router.
Drill a hole in the base of the leg for the threaded insert.
Insert the insert.
Chamfer the edges of the 2x1/4 such that it fits into the back of the photo frame.
Cut into 3" lengths.
Screw onto table legs.
Stain a nice color.
Print 2x3 beer labels, place in frames and slide over mount on the tap handle
I can add more step by step photos of needed, but I dont have them to hand
These cost $4 for the table leg, $1 for the frame, $.50 for the inserts and the rest (2x1/4 and stain) was already in the garage. Better than $40 a tap online.
