I finally bought a solid substance insert. Yes after all the discussion
about making my own I bought one. Time issue. I'm satisfied with the
flatness of the insert and have it installed in the table saw. I ran a
couple test cuts and am still seeing teeth marks on the wood. In a lot
of places it's as smooth as glass except for the teeth marks. I remember
reading several weeks back about someone having a WWII that had a wobble
in the blade, the blade itself wasn't flat. Is there an easy way for me
to test the blade I have? Setting it on a flat surface and see if it
rocks comes to mind, is this a valid test?
For those that own the WWII, are you seeing teeth marks at ALL in your
cuts? Maybe I'm just too particular? The cut is very good, but if the
rest of you are getting cuts without teeth marks, that's what I'm after.
Thomas, providing your saw is properly set up, try loosening the arbor nut
and rotate the blade 180 degrees on the arbor and retighten the nut.
No blade or arbor is perfect. You may be witnessing two extreme situations
coupled together. Sometimes rotating the blade 180 degrees will cancel the
90% of the time I see no tooth marks with either of my WWII blades. The
other 10% is wood that is not perfectly flat or straight or my feeding
Here's something else that I've noticed about the WWII. Seems to me that
I have to force the wood through the blade. I know enough to not go
faster than the blade will cut, but it still feels like I'm forcing the
wood through compared with other blades which are rip and combination
blades. That's regardless of thickness or species of wood.
That would be me with the wobble! ;-) I checked *one* tooth
with a dial guage at the front and back of the table and it
was out. I have other blades that were right on. My
replacement WWII is perfect, no runout. If you dont have a
dial guage, here is a simple test;
Take a small piece of dowel or a "chopstick" and clamp it
good and tight to the miter guage so that it *just* touches
a tooth edge. Rotate the blade buy hand (with saw
unplugged) to see if the teeth hit evenly. If some touch
and others don't, mark one that does touch and repeat the
test after sliding the miter guage to the back of the blade.
Repeat both tests with the blade rotated 180 on the
arbour. If all the tests come out the same (with the marked
tooth still hitting the stick) the blade is out. If there is
ANY variance in the test, then the arbour is not true, or is
not lined up properly with the miter slot.
