AMF (Almost Free) Pocket Hole Jig
Author: Suwat PhruksawanDate: 12 May 2005
The AMF (Almost Free) Pocket Hole jig is nothing but a piece of hardwood block with a set of holes drilled at 15 degree angle.
To make this jig, I started with a scrap piece of 1x3 maple about 6 inches long. I made 3 holes about 4-5 inches deep at the top of the block using my drill press and a 3/8" brad point bits to start and then use a 3/8" auger bit on my portable drill to continue to the depth I need.

(Note: I positioned the holes so that it will let me drill two holes on the 1x2 stock and 3 holes on the 1x3 or larger)

Then I use my table saw to cut the block at 15 degree angle and make sure my cut cross the drilled hole.
Once that's done, I flipped the cut off and glued the pieces back together. When the glue dried, the jig is ready to use. There you have it, the AMF Pocket Hole Jig.

(Note: you can also add a piece of fine grit sandpaper to the face of the jig so that it will grip the work better.)

My complete pocket hole system includes this jig, a long-shaft phillips screw drive bits ($2.00), an auger bit with a self-start tip (about $11 from the local home improvement shop) and a box of self-drill screws ($5.60). The total set up cost me less than $20.
Although it might not have all the bells and whistles of the commercial jigs, the performance and the accuracy is quite impressive for me. After all, it's almost free and the time it takes to build is probably less than going out and buy the jig from the store or order it online.
