I'm learning stuff...
As my kitchen upgrade continues, I had the pleasure of ripping about 100 li
near feet of 1 x 6 Poplar this weekend. The pieces ranged in length from a
few that were over 60" to large number between 25" and 35".
I was using a 40 tooth GP blade, Freud D1040X. The ripping went very smooth
ly and I got a pretty good edge on all boards, but I did run into an intere
sting (at least to me) situation.
I learned that the darker the Poplar, the greater the internal tension and
the more apt that the kerf was going to close around the splitter. In some
cases I wasn't able to rip more than halfway through the board before it wo
uld bind up. Early on I was pulling the boards back out (with the saw off,
of course) flipping them and coming in from the other end to complete the r
I eventually got to the point where I was putting the darker boards aside,
ripping the "lighter" ones with the splitter installed, and then (somewhat
nervously) ripping the darker ones without the splitter/guard. I don't know
for sure that all of the darker ones would have jammed around the splitter
, but I can say for certain that none of the lighter ones did.
I have a 24 tooth ripping blade, but it is in serious need of sharpening. (
In fact, I dropped it off at a saw and knife shop this morning) The 24 toot
h cuts a wider kerf than the D1040X, so I might not have had the binding pr
oblem, but I don't think it was sharp enough to have given me such a clean
edge. I have read about internal stresses causing kickback and other issues
, but this was the first time that I actually experienced it first hand - n
ot kickback, but the closing of the kerf on the splitter.
In any case, the ripping is done, I now have to wait for a decent dado set
to magically appear in my shop so that I can start on the grooves and stub-
In the meantime, I'm going to build a *real*
cross-cut sled to replace one
I made years ago when I had even less of a clue than I have now. It works,
but just barely, and it's not big enough for the MDF panels I'll need for t
he kitchen doors.
