Uneaven thickness when planing. how do i adjust
You mean you're getting speed bumps? Do you have the blade setting tools that came with the planer? You need them, it will be hard to do without them. It is a little C shaped jig that rides on the drum over the knife, you have your knife sharpened and set in the drum, snug, not tight,under the knife are adj screws, you run the knife setter around the drum and just scrap the top of the knife, do not pull the knife, just go over it barely scraping it, then snug it up, do not tighten anything yet, move on to the next screw, do the same thing, then the last screw, then go back to the first, still good? second, third, now, tighten them up, the setter doesn't pull the knife, just barely scrapes it, but it does hit it. Now do the other side. Both knives will be set the same, no more speed bumps, or uneven cuts. To move the knife back in, if you brought it out too far, use a block of wood to tap it down, make sure you put the elevation screw down first. Do not answer the fone while doing this. It is serious stuff, when those knives start flying. Hope this helps.
