Building furniture? You need a Kreg Jig. It is seriously a wood working game changer. With a Kreg Jig, you can easily build joints in minutes – without messy glue (if you want to use glue, you certainly can). It is what I use for all my projects here, so if you are attempting to follow any of the plans from this site, expect for it to call for the ultimate joint tool for woodworking: the Kreg Jig.
