EZ Link

First off - Hello to everyone.

I have been in woodworking as a hobby for a few years. I am going to retire from the Postal Service within the next month and am hoping to spend many more hours in my shop.

I just bought a Router Workshop EZ-Link jig and already have questions. It might just be me, but the instructions do not seem to cover much (I might even be missing some). Are there instructions that I could use to tell me which side of the drawer to rout facing up or which side is supposed to be routed facing down for the drawer to fit together? Also, is there a formula to show me how much I allow for the dovetail measurements (length,width, height) to fit the opening for the drawer.

I hope someone can help.

thanks
