I realize the pictures I posted may not make it clear what the Clincher Fence System does and how it works, in fact, I didn't either until I did some searching and still didn't find a lot of information. Here is a link to what I believe to be a copy of the information on the VHS tape included with the Fence. It will give you a better idea of how it works and what it is capable of doing. Here is the link to the first one on YouTube JoinTech 03 Jointery (Box & Dovetail Joints) (youtube.com) I am not sure if links to YouTube are allowed even though I tried to find out in the FAQ. If not and it is removed, you can do a search for Jointech Clincher Fence System and find then there. The poor quality of the YouTube video I think is because it was copied from the VHS tape.
