no knife setting gauge for ridgid 6″ jointer JP0600
Hello all! I need to change the blades on my Ridgid JP0600 6″ jointer. This jointer has springs under the knives and came with a knife setting jig, which for the life of me I cannot find anywhere. Ridgid sells parts of the jig, but have discontinued the rod that the guages attach to. I have made the jig that John White shows on the finewoodworking video, (he’s a genious!) So I guess my concern is since my blades have a spring under them, forcing the blades up, and the supplied blade setting gauge is used by placing over the blade and pushing down to force the blades down against the springs in order to get the proper alignment. I gather that John Whites jig is designed for use with blades which have jack screws so the blade pops up to click onto the magnet, keeping it in alignment while you tighten the jack screws. I’m thinking that this jig might still work with my jointer, i’ll just have to press down and tighten the screws, but before I remove the knives and find a problem i’m not seeing now, I was hoping that maybe someone has run into this situation or has more knowledge with this type of problem than i do, and can set me straight. Any comments would be welcome! Thanks everybody! George

You don't relly need a blade jig for a jointer. you can set the knives to the outfeed table. The jigs only give you a starting place and further fine tuning is necessary for a perfect set up. Once you begin to tighten up the gibs, the springs won't do much and won't be a problem. Un plug the jointer and remove the guard. Use a straight edge, such as a blade from a combo square. The short point of the knife bevel should show about 1/16" above the edge of the cutterhead. Place the straight edge on the outfeed table with the 8" mark even with the table edge. Rotate the cutterhead and adjust the height of the knives so each end and the center of each knife hits the combo blade and moves it ahead 1/16". This will take a little fussing but will result in accurate knife height. If the knives are a bit too high with some test cuts, just raise the outfeed table a touch. In the picture, I'm using the wrench to move the cutterhead back and forth, the small srewdriver to pry up the knives. Your test cuts should result in the board landing perfectly on the outfeed table and straight arrow edges.
Hi, hammer1! thanks for your guidance on working with my jointer. with your exellent description and invaluable pictures, i was able to get my jointer up and running properly again! The part about adjusting until the straight edge moves forward 1/16" sounds so simple! The fact that i'm just now getting back to you shows how simple that step is! I'm so tickled that my jointer is working so good. probably better than it ever has. and I owe it to your kindness. Thanks again, George
