Earlier I posted my experience putting a new Jet JWP-160S 16" planer
together. Several on the WREC warned that blade changes with the motor
above the access plate might be a problem. I just finished my first blade
change and it was pretty easy. The access cover had 4 screws and the dust
port has 3 lower screws that have to be removed. One of the cover screws is
partially under the motor, but it was no problem. Once the cover is off, I
had to remove a plastic deflector shield held by 3 screws. Two of the
screws had to be loosened with an open-end wrench due to the motor, but
there was penty of room. The cutter head is toward the outfeed and there
was plenty of room accessing the blades from the backside. Loosened the 5
gib bolts on the 1st blade and the springs lifted it up. There is plenty of
room to lift the blade out with finger tips on the ends of the blade. A
little cleanup and the new blade (Jet) slipped in. I pushed it down,
compressing the springs, till it stopped against 2 jack screws. Snugged up
2 of the gib bolts and checked with the guage.....perfect. Tightened the
gibs and did the same for the next 2 blades. No adjustments were required.
That might be a different story after I change to blades that have been
sharpened, but the jack screws seem to make that easy. Total time was about
1 hour. Next time should be faster. Won't have to read the manual 10 times
for each step......Can't be too carefull. The new blades cost $155! Yikes
Maybe next time it will only take 59 minutes. LOL... Practice makes
I was watching a MiniMax combination machine video. They showed how to
change out the 3 double edge disposable 16" blades on the planer/jointer.
Tap the gib with a board a couple of times, and simply slide the blade
horizontally through a small hole in the side of the planer. To replace,
slide the blade back through the hole under the gibs and move to the next
blade and then the next. THAT's IT!!!
The first time you turn the planer on the centrifugal force wedges the gibs
against the blades in perfect alignment.
Life is tough.... :~) How long do those blades last you. I was kinda
surprised that they put disposable blades in that machine, although if you
pay to have your blades sharpened I suspect the replacements may be a wash.
I resharpen mine and disposable blades would therefore be more costly to me.
The way I read it, he bought an extra set to use while the other set is sent
for sharpening, not that he's completely replacing the first set. Makes
sense if you don't have your own Tormek or suitable jig.
Note how he referred to how it might be different when he puts sharpened
blades back in, i.e., when the original set comes back slightly narrower.
That is also a question I am asking. I ran about 250 board feet
of cherry (rough) through it and the blades were definitely getting
I ran another 250 through on the replacement blades last weekend
and had the same result. Is the problem with the lumber or is it the
