Why the DeWalt DW735 Snipes, and What Actually Changes It
If you own a DeWalt DW735 and your boards come out with a deeper cut at each end, this page explains why that happens, why most of the usual advice helps some owners and not others, and what to do about each case. It is the long version. Links to shorter articles on each part are at the bottom.
The short answer
Snipe on the DW735 is a deeper cut in roughly the first and last two to three inches of a board, running the full width, repeating on every board you run.
Two separate things produce it, and most arguments about snipe are two people each describing one of them. One is the board pivoting on an unsupported overhang. The other is the planer's own carriage moving when the load on it changes. They land in the same place on the board and they add together.
The second one is the one almost nobody names, so here it is. The two feed rollers and the cutterhead sit on one carriage. Both rollers press down hard enough to squash the board noticeably into the rubber. Through most of a pass both rollers are loaded and the carriage sits still. At the moment a board enters, only the infeed roller is carrying it. At the moment it leaves, only the outfeed roller is. The force on the carriage changes at those two points, the assembly flexes a few thousandths of an inch in response, and the cutting plane moves closer to the board.
DeWalt says much the same thing in the manual, in a line most owners never read. Explaining why the planer has no manual carriage lock, it credits a device built into the four threaded posts with minimizing what it calls "the movement that causes snipe during planing".
That is the manufacturer describing snipe as movement inside the machine, in print, in the box.
Two different things both produce snipe
Mode one: the board pivots. A board long enough to hang past its last point of support has weight acting on a lever arm. That weight pivots the board about the table edge or the roller and tips the end that is still inside the machine upward, toward the knives. It also presses the board harder into the roller on that side, compressing the rubber further than it would otherwise sit. It happens going in and coming out, and it gets worse with longer, heavier stock and with less support.
Mode two: the carriage flexes. The one described above. The load on the carriage changes when it goes from two rollers carrying the board to one, the assembly moves, and the cutting plane comes down. This has nothing to do with the board at all, and it happens on stock that never overhangs anything.
Both deepen the cut in the same two places, so on the finished board they are indistinguishable. That is exactly why this argument never settles in woodworking groups. Two camps are each describing a real mechanism and each concludes the other is wrong.
Which one you have, in ten minutes
This is the most useful test on this page and it costs you one board.
Run a short board. Short enough that it never overhangs anything at either end, carried by the bed from the moment it goes in to the moment it comes out. No overhang means no lever, so mode one cannot be acting.
If the snipe disappears, support was your problem. Extension tables, a roller stand, a long auxiliary bed, or simply holding the board level as it enters and exits will fix it. That is the cheaper outcome and the better news.
If the snipe is still there on a short, fully supported board, you are looking at mode two. No amount of support will touch it, which is worth knowing before you spend a weekend building a bed.
Most shops have some of both. The test tells you which one dominates for the work you actually do.
One more observation. If you improve one end and the snipe turns up at the other, that is load balance rather than support. A support problem at one end of the machine does not respond to a change made at the other.
Why longer tables help some people and not others
With two mechanisms on the table, the community's oldest argument resolves itself.
A long auxiliary bed or a pair of extension tables does two useful things. It removes the overhang, which removes mode one. It can also correct alignment, if the infeed and outfeed tables were sitting out of plane with the main bed and bending the board as it passed. What it cannot do is change the force on the carriage.
So an owner whose snipe was mostly pivot builds the bed, watches it vanish, and recommends it sincerely for the rest of their life. An owner who works short stock, or whose machine flexes more, builds the same bed and gets almost nothing. Both are reporting accurately. Neither did it wrong.
Angling the feed tables upward is the same story with a sharper edge. Tipping the outer ends up pre-compensates for the droop, which is why it works on mode one. It does nothing for mode two. And it brings a problem of its own: on thicker stock the board spans between the raised outer edges and the rollers cannot press it flat, so the middle is cut deeper than the ends. You trade a step at each end for a gentle bow along the length, you lose planing capacity, and the thickness gauge stops reading true. We go through that trade in should your planer tables be level or angled up.
Lifting the board by hand and using a roller stand both act on mode one, which is why they are the most repeated advice in the hobby and why they genuinely work for the people giving it.
Sacrificial boards are the interesting exception. Running scrap ahead of and behind your workpiece keeps both rollers loaded through the whole of your good board, so the carriage never changes state. That is the one folk remedy that acts on mode two, and it is also the one people describe as the most reliable. That is not a coincidence.
What is happening inside the machine
The DW735 carries its cutterhead on four threaded posts. The infeed roller, the cutterhead and the outfeed roller all travel together as one assembly. Raise the crank and all three rise. There is no part of the machine that holds the board down independently of the rollers.
A pass has three states.
| Stage | What is carrying the board | Result |
|---|---|---|
| Entering | Infeed roller only | Partial load, carriage sits lower, deeper cut |
| Middle of the pass | Both rollers | Full load, carriage stable, correct thickness |
| Leaving | Outfeed roller only | Partial load again, deeper cut |
The length of the sniped section is not arbitrary. It is set by the distance from the cutterhead to the roller, because that is how far the board travels between the handoff and the knives. That is also why the sniped section tends to be a consistent length on a given machine rather than varying with the board.
The pressure bar argument, which is the serious objection
Sooner or later, someone who knows machinery will tell you this: industrial planers have a pressure bar, the DW735 does not, and without one there is nothing holding the board down at the moment it passes the knives, so snipe on this class of machine cannot be fixed.
The premise is correct, and the people who make this argument usually know more about planers than the average commenter. It deserves a real answer.
On a larger planer the cut happens inside a sequence. Infeed roller, chipbreaker, cutterhead, pressure bar, outfeed roller. The pressure bar sits immediately after the knives and presses the board firmly against the bed right where it is leaving the cut, and it does that independently of whatever the feed rollers are doing. That independence is the point. It separates roller behavior from where the board sits relative to the cutting circle.
The DW735 has no equivalent member. Two rollers, a cutterhead between them, and that is the extent of the hold-down. So yes, the premise stands.
Where the argument overshoots is the conclusion. It treats a pressure bar as the only way to break the link between roller behavior and the cutting plane. It is one way. There is a second one.
The second route: make the force swing smaller
A pressure bar works by refusing to let the board follow the change in load. It corrects the error at the point where it matters.
The other approach is to reduce the change itself.
What loads the carriage is spring force. The rollers are pushed down by springs, and spring force rises with how far the spring is compressed. The stock rollers on a DW735 travel further down into the board than they need to for reliable feeding, which means they are carrying more force than the job requires, and the whole of that force is what switches on and off at the two handoffs.
Limit how far the rollers can travel down and you lower the force they carry. Lower force means a smaller difference between the two-roller and one-roller states, which means a smaller change in flex, which means the cutting plane moves less.
You arrive near the same place by a different route. Rather than resisting a force swing, you reduce the swing that needs resisting.
This is also why roller pressure is the wrong thing to ask about. People want to know how to reduce the pressure, and reducing it directly costs you feeding grip, which brings problems of its own. What matters is bounding how far the roller travels, which is a question of height rather than of force applied. The DW735 gives you no adjustment for roller height from the factory, which is covered in can you adjust the feed rollers on a DeWalt DW735.
What DeWalt's technicians told one owner
One owner sent his DW735X back to the factory because of snipe. Technicians made their own test cuts on his machine and returned the board to him along with a verdict: the snipe was within acceptable limits for the model, confirmed at multiple levels of management. He had the extension tables. He had made, in his words, a million micro adjustments.
That is one owner's account of what he was told rather than a published DeWalt position, and it should be read that way. But it supports the part of the argument that is correct. Snipe on this machine is designed-in tolerance rather than a defect in your particular unit or a failure of your technique.
Designed-in tolerance is something you can engineer around. That is a more useful conclusion than impossibility.
The honest limits
Four things need saying plainly, because overclaiming here loses exactly the reader who understands machines.
If your snipe is mode one, roller height adjustment is not your answer. Support is. Run the short board test before you buy anything from anyone, including us.
This does not turn a benchtop planer into an industrial one. A 2,000 pound planer resists flex because it weighs 2,000 pounds, with a pressure bar on top of that. A DW735 with its roller travel bounded is still a benchtop machine on four lead screws. The gap narrows considerably. It does not close.
Zero is the wrong target. What owners who dial this in carefully report is snipe in the range of one to two thousandths of an inch, which on most work sits below the depth of a normal sanding pass. One customer working to puzzle-making tolerances measured in that range. Another measured about a tenth of a millimeter along the full length of his boards with no lifting technique at all. Those are real numbers from real shops, and they are also not zero.
The two ends are separate. The infeed and outfeed handoffs have their own geometry, their own springs and their own wear. Getting both balanced takes a test board and small increments, one side at a time. Why snipe moves to the front of the board covers what to do when you improve one and notice the other.
Why it often gets worse over time
A common report is a machine that ran clean for its first year and started sniping later. Nothing broke. Several things drift, and they all push the same way.
- The roller rubber hardens with age and with cold, which changes how it compresses and how much force it carries.
- Pitch and dust glaze the rollers, changing grip.
- Blades dull, which raises cutting forces.
- Some aftermarket cutterheads are made to a smaller diameter than the original, which shifts the relationship between the rollers and the cutting circle so the rollers press relatively deeper.
Every one of those changes how much force the rollers put on the carriage, or how much the carriage moves when that force changes. On a machine with roller height adjustment, drift like this is a maintenance item. You check the setting, reset it, carry on. The DW735 has no setting to reset, so it drifts away from where it started and stays there. My planer did not used to snipe works through the full list.
Before you change anything: is it actually snipe?
Snipe has a narrow signature. A deeper cut in the first and last few inches, full width, consistent board to board. If what you are seeing does not match that, nothing on this page will help you.
Thin raised lines running the length of the board are nicked blades. Rough torn patches at knots are tear-out. A band of over-cut partway along is a feeding hesitation. One edge thicker than the other across the whole length is the cutterhead sitting out of parallel with the bed, which is a different problem entirely.
Here is the test worth running before anything else. Take a board longer than you need, run it, then measure the thickness with calipers at four points: one inch in from each end, and two places in the middle. Write the numbers down. If the ends are consistently thinner than the middle, you have snipe and you now know how much. Plenty of people chase snipe that measures under a thousandth and would vanish in sanding.
How to read the marks on your board goes through each case. If it turns out to be a nicked blade, we would rather you found that out before buying anything.
Where to go from here
Run the short board test first. It takes ten minutes and it decides everything that follows.
If support was your problem, build the bed or buy the stand. You do not need anything else and you certainly do not need us.
If the snipe survived a short fully supported board, you have the carriage flex version, and you have two honest options. Manage it on every pass with sacrificial boards, which work and which you will be doing forever. Or change how far the feed rollers travel into the board, which is what sets the force swing in the first place.
