Topic tags/keywords: dw735 snipe play backlash

I have been getting some snipe with my dw735 and trying to resolve the issue or minimize it. My old DW733 has been a better planer for me with regards to snipe. I thought getting the tables would help lower the amount of snipe but no luck there. I checked all the bearings and there is no play how ever after placing my dial indicator at each post and pushing down on the corner one corner has a significant amount of play. The other corners are a few thou how ever the bad one has a good thunk. I’m thinking the auto post locking mechanism has loosened on that post and want to snug it up. Has anyone attempted to do the same before?

I have done a few searches on the matter and the closest I can find is people with jammed posts but no resolution.

I have the 735 with no snipe at all. Many complain about snipe with this and other portable planers. Before we can be sure it’s a mechanical problem, first we must take a closer look at how the tables have been adjusted.

First of all, you got the optional tables, way to go. They are an absolute must.
Raise your planer height high enough that you can easily slip a level or straightedge under the rollers. Just set the straightedge on the planer bed and tables. The straightedge should touch the first infeed edge and the far outfeed edge, and nothing else. Basically you should see daylight under the level. The table extensions need to be raised up at their far ends.

For me, it took raising the infeed and outfeed tables about 1/8” above the planer bed to eliminate snipe. You would think setting the tables flat with the planer bed would be best, but that isn’t the case.

I’m not saying there isn’t a mechanical issue with your planer too. Just check this first.

Thanks for the reply. That is the first thing I did when i got the tables. I used my veritas straight edge to adjust the tables flat to get a setting for the leveling bolt closest to the machine and then added a penny to each side of the bed and adjusted the outside of the tables to be level with that. This is to support the unsupported wood as I recall? My problem is even on shorter boards it seems the whole cutter head assembly (top part) moves more then it should while wood is going under it. I understand it should move some but one post moves a lot more then the others. I will try and test this tonight and try and put some clamping pressure on that post and feed some wood thru.

Try increasing the gap to two dimes or approximately 1/8”.

As far as the head movement, do you have a loose post? I believe they screw on from the bottom.

Here is what I found tonight.

I took the cover off and the chain looks good. I took some videos of what I found though.

Dial Indicator touching cutter head frame. Obvious sound and can see the cutter head easily moving.

Dial Indicator on ring that rotates under the cutter head when you turn the wheel. No movement in dial indicator but can hear it moving.

Wow, I would suggest that you contact DW or a service location to see what they have to say.

I had a chance to watch the videos you posted. I don’t know if DeWalt has a spec for backlash, but if they do, I’d wager to say that .004” is within specs.

I’m not even sure backlash is the problem. Pushing down on the planer without a board in the machine isn’t really normal operation. I pushed down on the four corners of mine, and while I didn’t have a dial indicator on it, I didn’t feel any real movement. I think part of what locks the cutterhead is compression of the rollers on the board. Without a board in the machine, I wouldn’t expect zero movement.

If you can’t dial in the machine for a snipe-free cut, I’m sure DeWalt will take care of it for you, but you might have to pay shipping if there isn’t a service center in your area.

If everything is okay with the machine I look to see if I’m getting snipe on the leading edge, trailing edge, or both ends of the board. If it’s just the leading edge for instance, you would raise the height of the infeed table slightly. Test it to see if lifting the board slightly as it enters and exits the planer helps. If that test decreases or fixes snipe, then bingo you know it’s a table adjustment issue.

I don’t expect very short or very long boards to emerge snipe-free, but an average sized workpiece with adequate support should come out just fine. You can carpet tape short boards to a sled if needed, but I like to plane them to thickness while they are still 3-4 feet long to avoid this. Boards longer than 5’ need additional roller stand support.

Hope you find a solution to the snipe.
