How high should jointer blades be set?
The proper height of the jointer blades should be just enough so that when you lay a straight edge steel rule across the outfeed table and the blade, when you rotate the blade backwards by hand, it will lift the steel rule ever so slightly, then move it backwards with the flow of the blade about one quarter to one …
What causes ripples on a board when running through a jointer?
Scalloped Cuts But it’s not unusual to discover a series of scallops or ripples along the freshly jointed edge of a board. Dull jointer knives can often be the cause of this.

But few jointers have cutterheads that are perfectly parallel with the tables, which means the cutterhead knives wonʼt be parallel with the tables either. Weʼll provide you with three options for setting the knives—one low-tech and two high-tech.
Do you need to adjust outfeed table on jointer?
If your jointer has a fixed outfeed table, you can skip this step—and should use extra care and time setting the knives to ensure that the table and knife heights are the same. If you can move it, you need to adjust the outfeed table to exactly the same height as the tops of the knives.
What’s the best way to draft a jointer?
With your drafting triangle, the job should take only a few minutes. Simply loosen the bevel lock, position the triangle as shown below, move the fence until you see no gaps at the table or fence, and retighten the lock. Use the same technique to set the 45° angle.
How can I check the alignment of my jointer?
Check the alignment by setting a triangle against the fence and touching the knife. Immobilize the cutterhead by inserting tapered wood shims between the head and bearings, as shown below. Loosen the knife gib bolts just enough so that the knife moves with firm hand pressure. Raise the knife slightly higher than the top of the outfeed table.
