It’s been a while since I posted an update. Things around the home have eaten up all my spare time, but I recently took my jointer knives out to be sharpened. They came back looking really good and I was excited to get them installed. This project is so close to being done, I just really need to press onward. Unfortunately, while trying to do so, I noticed a problem, so I’ll explain what I did and maybe someone can help me with my trouble.
I bought a piece of glass at habitat restore for 50 cents. I put that piece on my outfeed bed and inserted the knife springs, knife gib, and cutter knife into the cutterhead. I pressed the blade into the recess and tightened the gib just enough to hold the blade from popping out under the pressure of the springs. then i adjusted the set screws (already in place on the cutterhead) to slowly force the blade back out. I’d rock the cutter back and forth until the blade just BARELY contacted the glass, so that I’d know the blades were level with the outfeed table. once I got the height just right, I tightened down the gib and all seemed fine until….
I went to turn the cutterhead so that I could install the 2nd of 3 knives and it hit the infeed table. I thought that maybe the problem was that I had the infeed table positioned as low as possible to give me room to work, so I raised it and thankfully it cleared (but barely). It seemed like I would just be limited to shallow passes on this machine until I rotated it a little further, only to find that then the blade got stuck on the outfeed bed as well. That bed was set as high as it could go. Maybe lowering it might help, but that doesn’t seem to be the right decision.
Am I missing something?Shouldn’t the jointer be able to function with the outfeed at full height and the infeed at any height? What could be causing this? I don’t have an expensive level to check the beds for perfect parallel, but they seems to be quite flat based on sighting down the beds. I would think there would be a little tolerance built in that I should be able to rotate the cutterhead without a problem. I know that pictures would probably help, but I don’t have a camera at the moment. Anyone have any ideas?
