RockDoggy’s Woodshop

As with many (but not all) woodworkers, my table saw is the most used power tool in my shop.  For the interested, it is officially a Sears Craftsman 10″ stationary table saw, model 315.228310.  It has a left-tilt blade, which I never realized was a feature to be coveted (or hated, depending on your views) when I bought it in 1999 or so.  Sears didn’t seem to recognize it as a significant feature either, since there is no mention of this in the owner’s manual.  It also has a rip fence that locks down in front, and grips at the back tightly to a rail that runs along the back parallel to the front rail.  It is, in my opinion, a bad rail system that is prone to kickback and bad cuts, but I’ll discuss that in a future post.

That’s not what I wanted to tell you about.  I want to tell you about the saw’s splitter, which I use religiously.  For about the last two months, anyway.

When I bought the saw, I had a little experience on a bench-top saw, and quickly found its limitations for the kind of woodworking I had wanted to do.  So, being a devout follower of Norm Abram, I bought a new contractor style table saw from Sears (money is always an object), and never took the splitter and blade guard out of their plastic bags.  I put them in a drawer and promptly forgot about them, and began using the saw Norm-style, sans protection.

I can already imagine the fright half of you feel at reading that, as well as the chorus of “me too” from the other half of you.  Well, as much due to luck as care, I have never had a table saw accident of any kind.  No severed fingers, no serious kickbacks, nothing.  Not that I didn’t deserve it, because I did some crazy things from a safety perspective.

It was the table saw class with Frank Klausz a couple of months ago, as well as episodes of Matt’s Basement Workshop podcast where Matt Vanderlist conversed with guest Hendrik Varju regarding table saw setup, use and safety, that finally converted me.  I searched my shop, and miraculously found the splitter, blade guard, and mounting hardware all hidden in my shop.  This is amazing to me, because I am really good at not being a pack rat, and I throw stuff away all the time.  Also, I have moved twice since purchasing this table saw, and I really cannot believe that I didn’t misplace anything!

I mounted the splitter, and verified it was parallel to the blade, and began to use it for the first time in nine years!

Table saw splitter and blade guard

Its features include the blade guard, which swings up and out of the way for blade setup; a splitter (not a riving knife, even though that’s what the saw’s owner’s manual calls it) that tilts with the blade’s tilt; and anti-kickback pawls on both sides of the splitter.

I have found the usage of the blade guard and splitter to be far less irritating than I expected, once the apparatus is installed on the saw and properly set up with the blade.  Of course, it isn’t usable with my crosscut sled, and can’t be used while my dado set is installed.  But for all rip cuts, it is in place and has not proven to be a problem.  Quite the opposite, in fact.  I find the leading edge of the blade guard to be a welcome reminder of the position of the spinning blade, and it makes it easier to keep my fingers away from it.  Now, I’ve always been scrupulously careful about my fingers while using the saw, but really, isn’t that what we all say right up until the first time we have an accident?

This apparatus does indeed have a down-side, though.  While it’s easy to use once installed, it is the installation and uninstallation that is the biggest problem.

Splitter attachment to the table saw

In the photo, you can see that the splitter is attached to the saw via three thumbscrews that are tightened and loosened with a supplied allen wrench.  There is no quick attach/detach mechanism.  Each time the splitter is to be installed, these three screws must be installed.  The two on the back support aren’t too bad, but the one under the blade insert (seen in the photo to the right near the blade) is almost impossible to get to, and is the crucial one for setting the splitter’s leading edge directly behind the blade.  The other two are manageable. Uninstalling the splitter requires using the allen wrench to completely remove all three screws.

With practice, I have managed to get the installation and setup time to less than ten minutes, though I must say, I’m not racing to get it done quickly.  I tweak it until it is right, regardless of how long it takes.  Removal is a matter of two minutes or so.

So what did Frank and Hendrik say that convinced me to dig out the splitter and use it?  Well, they discussed in great detail the importance of the splitter or riving knife in preventing kickback.  Honestly, though I may have heard it mentioned before, I never realized with any clarity that the splitter played such an important role.  But when properly aligned with the blade, it keeps the rip cut firmly against the rip fence, making kickback much less likely.

Though I had never experienced kickback myself, I had come close a few times.  My saw’s motor is no more than 1hp, and so when the workpiece binds against the blade, most often it just stops the blade.  Like I said earlier… I’ve been lucky.

So add my voice to those advocating the splitter.  I haven’t had to lose a finger, or suffer a kickback punch to the gut, to come to that realization.  But my experience with this saw, combined with the words of these woodworking masters, made their impression on me.
