There are thousands of posts on this subject, but the best way is to assume it’s going to happen and start with a board that is x inches longer than the project requires.

Whoa, wait a sec. Don’t take snipe as inevitable. I’m a n00b with my new Grizzly jointer. I was getting snipe when I first set it up. Are you new to using a jointer or just got a new one to REPLACE a jointer?

If you’re new to using a jointer:
Make sure you set the outfeed table according to the manufacturer’s instructions.
Use LESS PRESSURE pushing DOWN on the board as it’s starting into the knives. You only need enough downward pressure to keep the board moving forward
Take extremely light cuts while you are getting used to how to feed the board.

For the record… once I got the OPERATOR trained (me) I had to adjust the outfeed just slightly different from what Grizzly said. VERY slightly.

If you’re NOT new…. well I probably shouldn’t be advising you as you probably know more than me :)

Talking about a planer, Charlie.

I have a planer and I was able to get it adjusted so that most of the time it has no snipe. But—- every once in awhile it happens. Therefore, I say cut it long just in case.

i lift the ends up slightly
when using planers that snipe

some have the cutter and rollers on the lift body
and when a board touches the in-feed roller
it raises the body (and the cutter slightly)
when it gets to the out-feed roller
it lifts the body and cutter too
(leaving you with snipe on the end)

when the board clears the in-feed roller
it drops the body and cutter down slightly
giving you snipe on the back end

this happens mostly with planers without a ‘lock’ on them

some just raise the in-feed and out-feed tables slightly
to try and overcome this

Snipe occurs so consistantly that it must be part of the natural order of things, and if it were eliminated the whole world of woodworking would implode. It’s all part of the entropy of sawdust.

Charlie, He said Planner, you said Jointer Which are we talking about? Being 16” I suspect planner. but I haven’t ever experienced planner snip on front end only on the last couple of inches with my Foley Belsaw 12”, and then seldom, and I take the last few passes VERY light and so get no snipe. The jointer is a different story and lots of woodworkers have a problem with them My 6” Craftsman doesn’t have an adjustable outfeed table but if you set the knife height so that the cutters advance a scrap of wood between 1/4- 3/16” when the rotor is advanced by hand with the machine unplugged, it reduses the probablity of snipe next to nothing. Maybe if 1yeldude1 is having jointer problems and his jointer has an adjustable outfeed table, still adjusting the knife heights different from the suggested installation instructions he can solve his problem.

in short, lift the board as it exits the planer or use “x” times longer board

leading edge would indicate your front roller is grabbing the board, then it hits the cutter before it can flatten out on the table and catch the outfeed roller. I suppose you could try to raise the infeed table but then you might have snipe on the trailing edge.

or maybe I have it reversed…LOL

I’ve spent countless hours trying to eliminate snipe on a Delta 14” planer. I gave up! I think a sled would work but I really like the depth gauge. So as mentioned above, I plan on it, leave the boards long and cut off the snipe at the end. I minimize it by taking very light cuts and flipping the board on each pass.

lift the board up when it exits the planer. How hard is that ? or add “X” amount of snipe

otherwise it would be better to get a second job just to pay for the expected waste of time resulting from trying to fix the inevitable failure : ))

its called “waste” landfill management skills : ))

in the event budget surpluses allow you to buy a better thickness planer then snipe can be removed but know you might have to bring your banker to buy the planer

check the bed rollers, they can be adjusted up and down, check manual, when raised it is easier to feed material such as rough sawn, but for precise dimensioning you can lower these rollers flush to the bed, just be sure to wax the bed to keep material feeding well

take a look at this… http://www.highlandwoodworking.com/understandingsnipe.aspx for some background

i’d be looking at the extension rollers on the in-feed side, maybe a little low.

Snipe on the leading edge is less common than on the trailing edge but I find that tipping both the infeed and outfeed tables up helps. When I have a piece that can’t have ANY snipe, I run a sacrificial piece of pine in front and behind it. PITA but it will work.
