hi david.
i am sorry to hear you are having trouble understanding the festool manual for the dovetail jig.
2 years ago when i was looking to purchase a dovetail jig, i came very close to buying the festool jig.
but, i realised that the learning curve would be quite steep and i would need all the help that i could get from the manual.
having bought a few festools over the last 10 years, experience has taught me that the manuals are useless.
that was the main reason why i decided not to buy the festool jig.
i decided to buy the leigh d4r jig because not only is the manual fantastic but you also get a dvd which explains the set up process too.
dont get me wrong, i love my festools, but this is one part of their business that they fail miserably at.
justin.
