Last week I started a thread asking about the Grip-Tite. There was not a whole lot of response but the ones that I did get were positive. I hate buying something like this without trying it out as some of those guys that demonstrate products can make it look better than it is. I though that it was a little expensive for what I saw but I went ahead and ordered it anyway. I opened the package and was a little dissapointed as they were smaller than I expected, I don't know why I was expecting something larger. Well let me tell you, I have been using them for the last couple of days and I am REALLY impressed. They are great for holding a board flat against the jointer fence. They are even better used on the tablesaw. As far as I am concerned they are the best safety device that I have and as a plus they hold to the fence and hold down the workpiece and they appear as though they will be effective agains kickbacks.
If you have been on the fence about purchasing them-----just do it. Did I say that I like these things?
Below is a picture using the Grip-Tites trimming a long board with dados cut crossways. I figured this would be a good test to see if they would be effective riding over uneaven pieces. I guess that I will have to admit that this was not a planned test but was a result of a little mistake on my part. They worked great as they held the board to the fence and rode over the dados with no problem.
