Aside from really pushing the envelope of what this unit was designed
to handle, it is of questionable heritage. I would be shopping for a
replacement while the holiday sales are ongoing.
That said, however, you could take a shot at tuning it up.
Make sure there is no play in the cutterhead bearings or the feed
rollers - repair or "fix" what is necessary. Use a flat surface
inserted into the planer bed (power removed), adjust the thickness
adjustment until there is a small clearance, and use feeler gauges to
check the clearances of the various rollers and blades - they must all
be parallel to the flat surface. Clean the rollers, or replace if they
are chewed up. Their diameter and resiliency are somewhat critical.
If the blades do not self-register when installing, try installing
them a little less proud. In other words, set them closer to the
centerline of the cutterhead. that should allow the feed rollers to
get a little more bite. The rollers not only provide feed assistance,
they hold the board against the bed securely.
Snipe generally occurs when a board is not held down against the
planer bed by both rollers - which is when first entering or exiting
the cutting/holddown/feedroller assembly. Make certain that boards
fed into the unit remain above the plane of the planer bed - they must
not droop AT ALL or it will snipe. Heavier and longer boards are
increasingly susceptible to this. I usually lift the ends of entering
and exiting boards with one finger to eliminate the snipe originating
from this design "feature". If you use roller stands, they must be
very carefully adjusted, under load, to be at or slightly above the
planer bed. Everything must also be absolutely level; in other words,
both the planer bed and the roller stands must be parallel, not
slightly lower on one side or the other.
Probably means thickness, not width - what would be the point of it
being a 12" planer. :-o
I wish I could, but I think I'm close to the limit of the connubial
friendship, if you know what I mean.
Great advice, thanks. I'll look at all of this. Now that I have a
jointer to really flatten my boards, the thicknesser is going to have
a much easier life. The rollers don't look too chewed up, and seem
Sorry for the confusion, the jointer is a new 8" which will take much
of my previous work away from my old thicknesser. The instruction
manual on it says:
"6. DO NOT perform planing operations on material shorter than 8",
narrower than 3/4", wider than 4" , or thinner than 1/2".
Notwithstanding that I don't know what the difference between thinness
and narrowness is, I assume this is a typo.
The jointing proscription does not include a width maximum, so I will
just pretend that I am really jointing anything over 4" wide :)

an Chinese to English translation, maybe they mean 4" thick instead of

IMO, snipe is inherent in a unit that isn't adjustable. On my old Craftsman planer, the bed is adjustable for parallel to the cutterhead, and the bed rollers are adjustable for height and parallel. The table gibs are adjustable. The feed rollers, presure plate, and chipbreaker are also adjustable, so the unit can be fine tuned to eliminate snipe. But it really does have to be carefully tweaked to achieve a snipe-free cut. I'm just saying having all those fine adjustments on a sturdy cast iron machine is the key here.
With your unit, the cutterhead and feed roller bearings may be worn. Also, the rubber surface on the rollers could be worn. If you're force feeding the unit, you're also losing any fine tweaking that could be applied, such as lifting the ends of the board. Also, the table might be worn so it has a crown under the cutterhead. And there may be slop on the cutterhead carriage or on the table support. Any little bit of slop will give the cutterhead that slight mechanical advantage it needs to pull up the workpiece and snipe it.
If you really are intent on salvaging the machine, I'd recommend making a flat table for it, and replacing any roller and sleeve bearings on the cutterhead and feed rollers.
Also check to see that there is no play in the carriage supports.
Also check and see what the height difference is, from the table, between the feed rollers and the cutters. Having the cutters sharpened will take a little off and may compensate for worn feed rollers.

Seems to be pretty tight, actually. It has had little use, but really
strenuous use. I suspect that my snipe was caused by insufficient
outfeed support using heavy boards. I will try it with the melamine
table inserted and much lighter, shorter boards.
The silly pressed sheet steel "in" and "out" feed trays are for the
scrap bin. A 3'2" melamine board will be the ticket, I hope.

The rollers don't appear worn much. I think I was just taking too much
off too wide, too long, too heavy and too hard boards. I will modify
my demands and present the thing with flattened top and bottom faces,
and take more, lighter cuts. I hope it works, coz her indoors thinks
I've had all my birthday/christmas presents for the next ten years :)
For what it's worth, you really gain nothing by jointing both sides of
the board, yet you can lose material in the process - not to mention
the time and blades invested - unless the board is really gnarled.
I believe tradition holds that the better/flatter side is first
jointed, along with one edge. THEN the planer is used to bring the
opposite face parallel and to the desired dimension. Generally the
table saw is then used to bring the other edge into line.
Unfortunately, the process involved in planing the board to an even
thickness can be repetitive if the wood varies in thickness
substantially. Patience is the key, as you remove just a bit with
each pass until the board is at the desired thickness. Sometimes the
first few cuts on a really bad board will result in losing contact
with the feed rollers in places, and will require assistance moving
the material. Hogging a bunch off in one pass stresses the planer,
dulls the blades, and often causes severe tearout. For this reason,
your final pass on both the jointed side and the planed side should be
a light cut (< ~1/64") to remove the undulations from the previous
heavier cuts. Whatever works for you however.
Yes, I understand that, Greg, but in this particular instance, to
favour my poor little thicknesser, a bit of help from my burly big
jointer will make things last longer. I have a set of 3 carbide blades
to put in this when I get sick of sharpening the HSS blades.
I would even contemplate hogging some high spots off a rough sawn
board with a tailed hand planer, a non-tailed jointer, or even a belt
sander with some nice 38 grit belts I have handy :)
Great advice, thanks, Greg. All the best to you and all the other
woodies for the festive season and the new year.
Sorry if I repeated the obvious, Jack. Haven't seen your nym before,
so have no idea what your experience - there are widely varying levels
of experience represented in this group. As well, many lurk and might
pick up a pointer. I'll shut up now. ;-)
Hope you finish your project in time, and have a pleasant holiday.
I lurk and pick up pointers all the time.

I have a rigid Planer from HD that was on sale for $200. I've had it
on home made stands and the floor and want to "bury" it into an eight
foot long "table" such that the table surface is on the same plane as
the in/out feed decks.
The melamine or formica idea sounds good - but it made me think of
that UHMF (?) plastic stuff they sell for maing slippery jigs and of
the "boat lumber" you can buy in 3/4" thickness that is really
slippery and tough as nails - not to mention "pricey."
I've not experienced too much snipe, but I never plane a board cut to
anything near the finished size and always take it down a "hair" at a
I flip it from one side and end to the other (four passes per board
per cut) to try and keep it as flat as I can as I take it down to the
required thickness. As I often do multiples, this can get a bit
confusing with six or eight boards being "processed" at a session.
Lots of shavings (anyone have any success making mulch out of shavings/
I have my eye on the Dewalt two-speed/three-blade model and wait for a
factory rebuilt or sale. Anyone use that model? Good, Great? Worth
the four hundred plus?
I would think that the rollers may have "dried" and gotten, thus, a
bit harder and smaller than when new. Wonder if soaking them in
something would help restore their size and grip?
Re-enforcing the in/out feed tables sounds like a plan - but steel
sounds better than wood or composites and might allow for the addition
of an adjustment mechanism of some sort. Tractor Supply has lots of
sheet steel and tube/angle/flat stock. If you can sacrifice 1/4" of
material capacity, a sheet of 1/4" steel laid through the opening and
supported on in/out feed sides with some heavy 1.5" angle should allow
you to create a solid bearing surface as flat and unbending as you
could hope for. Mounting it to the planer and the whole thing to a
strong "table" should take care of everything sabe the (possibly)
Is the cutter head accessible? Can you see bearings and races? If so,
might you try replacing those? Are there bearings and races on each of
the rollers? Might they be worn and sloppy as well?
Don't re-design the tool, repair it and improve on it. Removing the
rollers is not a sane and safe option (as has been said repeatedly).
Don't remove the feed rollers ! It's dangerous to try to use your planer
without them. Instead, clean them. I usually use paint thinner on them and
then follow it up with 409 or a similar detergent type cleaner. After a
good scrubbing they should work like new again.
Using a piece of melamine for a feeder bed will help with feeding and it
will reduce snipe some, but I have had the best success by inserting a piece
of scrap wood of the same thickness immediately following the good piece of
wood. Butt the ends together and don't leave any gaps. If you do this right
the planer will think it's running a longer board and the snipe will occur
on the scrap piece. All planers produce snipe. The better quality planers
produce less. My newest planer, a DeWalt 735, was supposed to be snipe free
according to the salesman. It's much better about snipe than my older
planer, but it still snipes, however, it's so little (a few thousandths)
that it can usually be sanded out very easily, so I still follow up my good
boards with a piece of scrap if I really don't want any snipe in my boards.
Good advice, especially when preparing/planing expensive material when you
can't afford to lose any of that precious figured stock to snipe. Having to
sand out even the smallest bit of snipe can really throw off future joinery
operations, and play havoc with the fit of things like M&T joinery down the
As others have noted, and in normal operation, I usually set the very ends
of both infeed and outfeed tables on my jointer a bit higher than level
(tapering both tables slightly downward to be flush with the planer bed),
and even doing that it is often necessary to lift the ends of the stock
slightly on entrance and exit.
To illustrate, and when I really can't afford to have any snipe whatsoever,
I build a quick n' dirty planer jig similar to the one on my Jigs & Fixtures
page, and feed the whole enchilada through the planer, with both leading and
trailing sacrificial stock of an appropriate thickness that will take the
snipe if I screw up the feed angle:
http://www.e-woodshop.net/Jigs.htm - (scroll down to "planer jig").
The one pictured was built for a very specific purpose (taking a slight,
after-the-fact ,warp out of some already assembled inset door frames), but
the idea is obviously adaptable for many situations where _no_ snipe is of
