    The way I’m thinking, not keeping an anvil tight would cost more in fuel, and possibly more wear and year on a machine.

    After messing around with my chipper and changing the bed knife, I discovered it isn't hard at all to adjust it. Takes less than 5 minutes with an impact and two wrenches.

    Fuel plus wear and tear are not increased as far as I can tell , just the chip size. Tossing knives would be like tossing chains to me. Invest , use , file , use again ...repeat

    A few years back, I had a Morbark 15 self-destruct when a knife broke while chipping. A scary experience with sharp metal flying in all directions. It was a knife that had been sharpened at least once or twice. I don't know if the knife was defective from the start or if it was compromised by the sharpening process. After that, I decided to just put new knives in whenever they got dull or damaged. We're careful about what goes into the chipper; no rakings and we leave the trap door under the feed wheels open.

    Brian. I don't understand Brian.

    Because I've never owned an expensive piece of equipment I have no idea what I'm talking/asking about.

    Gotta do what it takes to set your mind at ease. I often think about extra precautions I take and steps I go through to have me feel comfortable with a situation. I know some people wouldn't do it and would save a few extra moments per job that way. I purposely choose to waste X, because, that's what it takes for me.

    Conversely when I was in my 20's I rebuilt a 16 inch chuck and duck that had metal go through it and tear up a bunch of things including the knife beds. I used a fabulous metal epoxy product called Devcon to make the surfaces flat again and installed the existing bolts back in with new knives once all was cured. Knowing what I do today I would trash that machine.
