    Dewalt 735 - snipe problem

    i have owned a dewalt 735 for 3 years now (without extension tables), and have had no problems with snipe until the past several months . the amount of snipe varies from 0.003 to 0.10 . prior to the snipe problem, i did not do anything fancy when i fed my wood except to hand-support the board as it went in and came out. now, if i put a fair amount of upward pressure on the board, the snipe is minimized. something seems to have changed. here is what i have done so far in an attempt to return to the "good ole times":
    1. installed extension tables with the outer edges as high as they will go; helps a little.
    2. checked out the machine thoroughly with a dial indicator and straight edge; table bed is flat to 0.005 or less; knife is parallel to bed by <0.001; rollers are parallel to bed by <0.002; front roller is 0.030 lower than knife; rear roller is 0.012 lower than knife.
    3. cleaned bed and rollers (already pretty clean).
    4. pulled off the right side of the machine and the roller sprockets, and pulled off the right bushing on the front roller. the bushing was in good shape, but i'm wondering about the spring. with 20-30% JAF (jim's available force) i can push the right end of the front roller up; however, i need 90-100% JAF to push up the rear roller.
    Questions :
    1. are the front springs the problem?
    2. any other suggestions to get me back to the "good ole times"?

    I have one of these too - and have the same problem. From new it was fabulous, no snipe. Now, almost but not every board has snipe. I have not investigated, as I tend to leave my boards long enough to cut the snipe off, but it is annoying. I thought that something must have changed in there. BTW i only use it for light home use.

    Same thing here. I have not used it very much but at first I could get rid of the snipe on the last part of the board by putting a little upward pressure on the outfeed side just as you were saying. Now, after using it a bit, that technique is not working any more. I can minimize it but still get a little. I hate to waste good wood.

    Ditto to all above posts. Currious to see if there is a solution.

    i am pretty much a light user also. i hoping that the SMC veterans will weigh in and save us all! i also wonder whether the "automatic" column locks may not work so well anymore. i might try replacing the springs and see what happens.

    With the tool unplugged, rut a long piece of MDF (like one of those pre-cut shelves) through the machine using double stick table to keep it on the infeed, outfeed and machine tables. Now run some material through and see if you still have the snipe problem. If you do, there may be a problem with the cutter head system and or lock. If not, table adjustments may be the key.

    Adjust your in and outfeed tables a tad high

    I also own this planer and had some snipe issues as I set it up. I like Jim's idea to check the alignment of everything. If that doesn't solve your snipe issues try setting a small thin metal rule like a 6" pocket rule on the far outboard edges of each table and use your straight edge to set the height of the in and outfeed tables. Run a test board and play with it, you might need a bit more. Setting the ends of the tables slightly higher than level will have the same effect as lifting boards as they emerge to reduce snipe. My planer has given me snipe free cuts for almost 9 months of service and for at least 1000 bf. I tend to run boards end to end to also reduce snipe. Good luck.

    Jeff,
    I agree, that would solve his problem but his OP states " have owned a dewalt 735 for 3 years now (without extension tables), ".


    Jim,
    I have seen the extensions for cheap now and again and would recommend them. An alternative would be a permenant install of the sled Jim B. discussed. Instead of acting as a sled it would become your new platten; extending out from the front and rear of the planer. A few of our favorite mags have had a version of this to cure snipe in extensionless planers. Of course all measuments and scales would have to take this into account. I know this goes nowhere near explaining why it is happening now and didn't before, sorry.

    Your correct, missed that. My mind seems to fill in the blanks with what it wants to see, vs what it there.

    That said, I would recommend buiding in/outfeed support using a set of roller stands, or investing in the DW tables.

    Ok, my 2 cents are a little high level but I like to always start with the "What Changed" question

    If I understand Jim's situation, it has been working fine for quite some time and only recently started to act up. The only thing that changed was the machine got older and had more use, eventually giving him snipe.

    If I have this correct, then this amature (me) is thinking it has to be related to one or more of the following:
    Something needs cleaning
    Something needs adjusting
    Something needs replacement (worn or broken)

    On a different tack, if it is a worn or broken part problem could it have anything to do with the DW734 problems prior to serial number 200440 see thread
    http://www.sawmillcreek.org/showthre...ighlight=dw735

    My DW735 has not yet given me any problems (other than some slipage fixed by cleaning) so I have a vested interest in watching the outcome of Jim's problem.

    Good Luck!

    Ben

    Here's an example of what I spoke of in my previous post:

    jim, glenn, and others

    thanks for your suggestions. i think my original post may have been a bit long-winded and confusing (see quote above) - i did install the extension tables in an effort to fix the snipe, with the ends high, but it did not fix the problem. i also checked my serial number and it is low, suggesting that it may need servicing - i'll give dewalt a call.

    Mine seems to have fixed itself. No more snipe. I didn't do a thing to it. Have been running some oak and cypress through it and no problem with either type of wood.

    allen,
    i'm just north of you in GA, would you mind stopping by and touching my planer. maybe that's all it needs! it turns out that the "service" issue mentioned earlier will not solve my problem. i've got the parts to replace the springs....now all i need is the time...maybe if i spent less time surfing SMC....naw!

    Ahaw---a new career. I would make the trip if it would work. Mostly my stuff breaks. First time that anyhing has fixed itself. I am holding my breath and hoping that it last. I ran quite a bit of stuff through and so far so good.
