I recently purchased the Rip Guide and have used it for 4 or 5 8 ' long rip cuts on plywood and MDF. I am somewhat disappointed with the quality of the tool.The fence which is plastic is not square to the guide bar. The anchors that clamp the base to your saw does not hold well because it is mounted again to plastic so when you tighten the the mounting brackets it begins to bend the mounting plate. Overall if I were in the market for another guide I would not purchase the Kreg Rip Guide. They should stay with metal fixtures as they originally had on so many of their earlier tools.
