wood/chuck drum chipper vibration

[campgroundguy]

I have a wood/chuck chipper with 16inch knives, I had the knives sharpend at a local shop and installed them myself. I noticed a vibration after i installed the knives. it may have been there before but I didn't notice it before. Where should i start to look for this vibration?

Did they sharpen them evenly? And check the drum bearing.

"local" shops that sharpen knives dont always do it correctly. the correct way to sharpen a chipper knife is to put them all on a horizontal grinder that does all the knives at the same time to assure you there all going to be the same width from your anvil and the same in weight. pull your knives and weight them. if one is off a few ounces youll ware through your bearings in NO time at all with the risk of hurting yourself or a employee if the drum was to crack from the vibration
