Title: Smoking Hot Walnut
Post by: Birdhunter on October 18, 2020, 03:57 AM
I was ripping some 8 quarter (2”) black walnut in my 3 HP SawStop fable saw when the blade came to a smoking stop. This was a relatively new Forrestt combo blade embedded firmly in my beautiful walnut. Stuck hard!

Once I freed the blade and took a 30 minute breather, I mounted a Forrestt rip blade. Cut like warm butter. First time I ever used a rip blade. Definitely the right way to go.

The rip blade does make a huge difference even on 1-1/4" stock (but mine is a PCS 1.75HP). For all stock prep. sessions, I use only the rip (1/8" 30T)...like cutting butter when compared to the combo. The Forrest blades are expensive but great. I only use the SawStop titanium blade when they are put aside for cleaning.

I actually just picked up a thin-kerf Forrest blade for help with thicker rips.  I also have a 20T 1/8" kerf rip blade, but the cut quality on it is not as good, so the thin kerf model is now there when I need to plow through 2"+ hardwood.

That’s very cool. Really shows how much difference a good rip blade makes.

I made the rip blade cut a little proud and cleaned up on my planer. The rip blade cut was ok, but not as smooth as the combo blade.

I usually re-rip on the table saw, with the last cut less than the blade kerf, say 1mm.

If the rip blade is clean this usually gives a good enough finish. Does sometimes need a run on the jointer, maybe 1 in 3 or 4 times.

Even the WWII combo blade 1/8" - 40T doesn't leave a furniture-grade edge. I handplane all show edges with a couple of light passes, following the grain direction.
