I am having some trouble with my jointer. I don’t know if it’s me, the machine, or normal. Every time I edge joint a board I get snipe at the end. Is this normal? I have a DJ20 I got used from CL and have not adjusted the tables at all. Thanks!

Sounds like the out feed table is too off. The board isn’t staying level at the end of the run.

I would at least check those tables. :) Just moving such heavy pieces of machinery can necessitate some tweaking afterward. That being said…. when I got my jointer it was brand new. I adjusted it per the manual and tried some jointing. It was pretty bad. I thought, “what’s WRONG with this thing?”. Rechecked everything. Tried again. .....awful…

Turns out it wasn’t the machine at all. It was me. Once I improved my technique, I had perfect results. I practiced by taking very small amounts off at a time. marking the edge, doing it again. Until I finally tweaked the OPERATOR into correctness (is that a word?)

On a planer it will snipe if if drops coming out. I think on the jointer it does it if it comes up at the end of the run. It’s pushing the board into the blades.

Thanks guys:) I will check the tables. I’m sure my technique is not yet perfected either;) I will keep working on it.

I always lift the end of the board a bit as it comes out of the planer. This eliminates the snipe. Getting the correct amount of lift requires some trial and error to find the right amount. Another solution is to use a longer board under the one you are planing. You can use a little double sided tape to stick them together if you find slippage to be a problem.

I have to agree with Charlie a bit on this one: A lot of the problems I have with my jointer is due to the technique of using the machine – It’s not easy – takes practice and coordination

Look online for some instructional resources

Sometimes I get a little snipe and most of the time I don’t. Technique is definitely a factor. I know it’s not the machine because I never touch the settings once it’s set up after a knife sharpening. One theory I have is that the profile of the unjointed edge as it passes over the infeed might be a factor, especially on a shorter board. In those instances a second pass seems to eliminate the snipe. Just my experience and I may be talking out of my hat.

I’d say it’s an adjustment on your table/s also

I just kept raising the out feed table until the snipe disappeared.

Check to insure that the out feed table isn’t sagging at the end and the infeed is parallel.
Technique is, or can be, a factor. Take light cuts. Keep pressure on the board near the infeed side of the cutter until the cutter is a bit past 1/2 the board’s length. Then, switch to pressure on the out feed end. Takes a little practice.
If the piece is bowed, start in the middle of the bow arc where the cutters don’t reach wood. Run it through, cutting just one end. Then turn it around, again start at the arc of the bow, and joint the other end. May take a couple passes on each end, but you’ll know when the cutters hit the (used to be) arc.
If all else fails, as with planing, consider starting with an over length piece and cutting off the snipe.

I agree that technique is a large part and there is a definite learning curve with a Jointer, but more often than not, snipe on a jointer is caused by the outfeed table being too low.

Thanks everyone! I am going to first check out my tables, then take a big pile of scrap wood and make a bunch of boards turn into saw dust lol. Hopefully by the end I will be able to joint without snipe:)

Try to make sure that after you feed the board into the jointer and have enough room in front of the blades
you transfer some feed weight to the front of the board, and then after it passes the halfway mark transfer
all of your weight to the outfeed table. Some good push pads with soft grip material might help make this
easier. Not sure if this is the real correct way, but it does work for me. Just grab some pieces of scrap pine
or other wood and practice until you get it right. Keep having fun in the shop. I have used a power feeder
on a big 8” jointer to joint some hard maple for a work bench, but other than that, I have just used the above
method.

Raise the out feed table until snipe goes away or is ever with the knives. Check out the link provided.

the outFeed table is either too low or not co-plainer with the in feed table they need to be adjusted
