Topic tags/keywords: jointer jet wood

I’ve had this jointer for little over 3 months and just noticed how much damage the table top near the cutterhead is receiving. I’ve only run a few boards of walnut and pine through it, and only take off 32nd of an inch in each pass. Can anyone tell me what is causing this, or if you have seen this before?

Loose knots or very dirty wood. The knives have a nice big chip where something came loose and dented the outfeed lip.

I notice my Delta DJ-20 has replaceable lips near the cutterhead. Must be a common problem to sustain some damage there.

If it were me, and I felt the damage was interfering with milling lumber, I’d use a random orbit sander with progressively finer grits to level it out. Not really worth having the infeed table re-milled for a small amount of damage.

Your jointer is new, so it stings a little more. My jointer is probably 20+ years old, so it’s taken it’s share of knocks. Trust me, it will get easier with time.
