I purchased this dado blade on the advice of some friends ... whom use it. My first reaction was, I NEED to enlarge the directions!! The instructions are printed in a very fine point font which, makes them very hard to read. So, I went down to my local kinkos and printed out a 50% enlargement(Now 11 x 17"....Problem solved.)(I also laminated the directions so that I could mount them on my shop wall)
