I have a Delta 37-190 jointer...looking at Amazon, replacement blades
are a whopping $55.
Can anyone recommend a better option? That just seems outrageous.
Amazon has a Freud C350 set of blades for only $21.95...does anyone know
if they will fit the 37-190? (There wasn't any compatibility info on
the Freud webpage, but the Freud blades are 6" x 1/8" x 5/8").
Check w/ the Delta site for sure, but that's a thickness and width for
most Delta although they typically used an 1/8" longer than nominal
I'd caution about expecting to receive the Freud knives any time real
soon...I've a set of planer knives on order since last October and just
received <yet another> delay approval e-mail yesterday...I've kept
renewing it as I don't need them immediately as I ordered them as a
spare set to have on hand when sending the carbide knives for
regrinding, but I'm beginning to think they're never going to be
fulfilled at the listed price.... :(
Stan - Amazon/Toolcrib has a lot of Freud dimensions to choose from.
The best thing to do would be measure one of your existing blades for
height, width and thickeness and then find the Freud item that best
matches. I ordered the C360 for my Grizzly G1182 and received them in
4 days (even with free super saver shipping). It turns out my jointer
really wanted a full 1" high blade and the darned jack screws they put
it at the factor will only work with a 1" and not a 7/8" blade, like
the C360. I could have returned and ordered the other set but I just
replaced all 6 jackscrews in my cutter head with ones a little longer.
That allowed me to back the screws out enough to actually adjust the
A quick google yielded no results to the dimesions the stock blades.
I'm guessing they are 6 and 1/8 or maybe 6 1/4", but you should check
just to be sure.
What size are the Delta blades? Mine are 3/32", so the Freud aren't a fit.
I also was horrified by the Delta price, and I eventually found some CMT
blades the right size at Cheyanne. Haven't actually used them, but they are
the right size.
toller: I think mine were 3/32" too, but I replaced them with the 1/8"
Freuds. I didn't have any problems with the added thickness because
the gib bolts accomodated it just fine. Hopefully I'm not missing some
blatantly obvious with running these knives.
I originally did that also, but the fine people here said that if the head
was designed for 3/32, putting 1/8" in was really asking for trouble. I
can't see why it would make all that much different, but would sure feel
silly having the head disintigrate from too much weight, after I was warned.
So, I sold the 1/8" on ebay for a profit (I had bought a set of closeout
Ridgid at HD for $10) and bought the CMT.
So, my guess is you are okay; I just didn't want to take the chance.
If I can locate some sort of scale I'm going to weigh the stock blade
against the C360. My guess is that they are darn close because
although the Freud is a 32nd thicker, it's an 1/8" shorter as well. If
a cutterhead is designed to be so sensitive that it's integrity may be
compromised because of 1/8 of an ounce total increase in weight then
perhaps it's already a danger. No where in my grizzly documentation
does it even mention the type of blades nor the dimensions for
replacements not to mention any cautionary text surrounding the topic.
Also, by replacing the factory jack screws with #10 flatheads I'm sure
some might say that's a no-no as well. For starters, a #10 didn't
thread pefectly (oops). I"m sure those weigh more as well (ooops
I'd be interesting in hearing a technical explanation if anything I've
done is blatantly wrong.
I do not believe this post.....why would you take a chance with getting
a mouth full of jointer knive to save a buck ..Do not change the screw
size or the knive change...I do not want you getting hurt......$55.00
is cheap....melt your own metal down and hammer out your own! Just not
practical...I have always had good luck with Freud...good quality and
fair prices....Please be careful!
Believe it. I was wrong in the width of the original knives.
According to Grizzly the 1182 takes 1"x1/8"x6" knives. What I tested
in my jointer were 7/8"x1/8"x6" knives.
Now, just for grins I put the digital caliber on both the original
knive and a freud, both claiming 1/8" thick. Remember, grizzly said
1/8 inch = 3.175 mm
Actual grizzly knife: 2.95mm
Freud C360: 3.20mm
Hardly a small difference if being overly sensitive as you claim.
Now, regarding the difference between 7/8" and 1" knives. Please, by
the time yahoo's get done learning to sharpen their own knives they end
up using a shorter knive. That is why the springs/jack screws exist in
the first place! And fwiw, the jack screw hole is threaded all the way
through the cutterhead, allowing a longer jack screw. So, if you are
trying to tell me that a "knife setting screw", of which plays zero
part in securing the knife itself, shouldn't be changed, well then
we'll have to agree to disagree. I do agree about messing with the
thickness of the blade and the gib design. However, the gib
design/integrity is in no way affected by the 1/8" difference in blade
I knew before hand about the implications of knife changing but I made
an informed decision based on the real actual data from my particular
situation. I'm no moron (you may disagree) and am very aware of the
dangers in the jointer and the power of the cutter head. By all means
don't try this !!!!
The problem isn't weight, it's the thickness and the design of the gib.
A 3/32" in place of a 1/8" (4/32") knife is potentially dangerous as
there may not be sufficient slot depth for the gib to press in before it
gets too high.
Re gib screws...the reason you need longer ones is that you're having to
make up for the thinner knife. I won't say your installation is unsafe,
I can't see how the knives fit in the head from here...if they've stayed
in for a while, that's probably good indication they'll stay from now
on...but, as a generality, I would <not> recommend a thinner knife.
