I turned off the saw and lifted the board away. The splitter came with it:
I'm sure it would've kicked back without the splitter. One thing I realized
was that I had no idea it was happening (other than it started to take more
pressure to push the board through), because I was watching the leading edge
of the cut not the trailing edge.
Maybe I can finish the cut by two opposing less than 1/2 thickness cuts and
split the last bit apart by hand. Would that work? I don't think I'll be
ripping spruce 2x4s their full thickness again any time soon.

With construction-grade wood, you takes your chances.
To finish the cut, I'd consider slipping some wedges into the existing
kerf to keep the wood apart and from pinching the blade, then settling
the board over the blade, testing, and then starting the saw well back
of the uncut porton, and slowly advancing the board through.
After a while this design splitter breaks. I use it also but have upgraded.
Microjig also sells this style splitter with a steel core covered in
translucent plastic. These don't break, as easily. Oddly I have only seen
the steel ones at woodworking shows.
Well *I* have a hafnium-plated ytterbium electro-plated, solid-core,
dynamically-balanced, oscillating-frequency, hand-polished knobs on
ALL my tools!
See here for opportunities: http://www.elementsales.com /
I cut my riving knife to shape with the plasma cutter, so there
probably _is_ a tiny amount of hafnium stuck in it somewhere.
I can't believe these plastic doohickeys could last "a while". With me
I'd side-swipe the things clean off the table before lunchtime.
Honestly, I waffled for a very long time before deciding to buy one of these
for just that reason. However I stopped to think that it was probably
better than nothing in the meantime, and in spite of the cost (it seems over
priced), I went ahead. I'd say a lot of the cost is worth the thought that
went into its design, which you see when you read the instructions for

Cute. Actually got me thinking about that Sawstop contractor saw
version. Checked the website. Still says Available Spring 2008. And
it says Status: Production PLANNING in progress.
Uh huh. One of those two is not right.
How long are ya supposed to season cast iron?
I rip 2 x 4's a fair amount. Just watch the cut behind the blade, and
if it looks to be closing, stop the saw, and stick a wedge in the cut
and finish the cut. Sounds like a wedge works better than a splitter
for this cut.
Got a bandsaw?
When I need to rip lumber like that, I always use the bandsaw. If I need a
smooth surface, I'll dress it on the jointer or the planer afterward.
As ZzYzx said, with construction lumber, you take your chances: you're dealing
with species that are more prone to doing this than most hardwoods are to
begin with; when you consider the additional factors of incomplete or improper
drying, and storage in conditions that don't exactly promote dimensional
stability, it adds up to more risk than I'm comfortable with.
Glad you weren't hurt. That new splitter may well have saved you from a

Yep.. I use mostly "almost dried" pine here in Baja.. hard to get anything else

Seems like the best way here is to buy 1x12's or wider in 10' foot lengths and
make my own lumber...
Reaction wood. I tangled with a piece of that once.
I was ripping a 1X8 pine board that started to close up and pinch the blade.
Like a dummy, I stuck a wedge in the kerf and tried to continue the cut.
After about another foot, there was a loud CRACK! and the board split.
Fortunately for me, the grain was fairly straight and it split roughly along
the line of the kerf or it might have kicked back.
Now I don't use much pine...preferring poplar instead for most projects.
And if a board starts to pinch the blade I generally discard it. The cost
of the wood would be MORE than offset by the cost of having my face
Pine is the main source of wood in my area, so I had to use it for the display
cases in the shop and for bookcases and such...
Like you, I've learned to feel the slight resistance when the kerf is closing...
been there So many times in the last year..
I just turn the saw off, pick up the board and finish the cut with the band
