Planer snipe

What you see

1. A dip, a slightly deeper cut, at one or both ends of the board.

Likely causes

Most-agreed first: the more makers name a cause, the higher it sits.

1. The board is not supported as it goes in or comes out, so its free end sags and tips the other end up into the cutterhead.

What to change

Change one thing at a time, so you know which change fixed it.

1. Support long boards level at both ends, with roller stands or a helper, and lift or catch the board as it leaves the outfeed side.

2. Keep the board flat on the bed and level from the start of the pass to the end.

Preventing it

1. A little snipe may not go away entirely; plane the board longer than you need and cut the ends off after planing.
