I know the Ryobi AH-115 inside and out and although they are discontinued, parts are still available. During that time period there were 3 planer/jointer combo units made, Makita, Hitachi and Ryobi all made their own version of the units but ironically, they were all made under the very same roof. Many of the parts are interchangeable especially internal parts, belts and knives.

I’m not familiar with the AP model although I think I’ve seen them. Check for similar versions thru Makita and Hitachi. As far as the knives go, I’m not sure about the AP but the AH version has the knives screwed into a blade holder and then bolted onto the cutter head with 8 bolts after the knives have been set to the correct cutting depth using the provided knife setting jig. I’m guessing you don’t have that jig with the machine ??

If the AP knives are first held in a knife holder and then bolted to the cutter head, you can remove the knife holder without loosening the knife and a machine shop can make you a setting jig out of a piece of aluminum fairly cheaply. Another way would be to measure from the lip of the knife holder to the sharp edge of the knife before you remove it from the knife holder to be re-sharpened. After re-sharpening you’ll have to reset to that measurement, it will take more time to get it right but it can be done.

Hope this helps,
