When ripping stock between the blade and the fence, what is the consensus on how narrow you can go on the table saw? I was trying to rip a 2-1/8” stock the other day, and I noticed the stock came out little tapered (about 1/32”). I had noticed that the wood was moving away from the fence at the back of the blade after ripping half way through. Then, I tried a wider stock (5”) and didn’t experience that problem. I am guesisng the way I am pushing the stock doesn’t work for such narrow stock.

As I write this I’m rubbing a pin sized gouge that I received in my thumb through gloves from not following my own safety rules about kickback but the best rule of thumb is wide enough that you can keep all your safety features on (riving and pawls, featherboard(s)) and use a push stick.

It’s always safer to cut a narrow piece off a wider stock placing most of the board between the blade and the fence.

The tapering you are experiencing is probably due to either a fence alignment issue or technique or a combination of the two. When ripping narrow stock I use a thin ripping jig. This is just a push block that straddles the fence and the face of it consists of a piece of 1/4” plywood with a 1/4” notch cut in the bottom. This push stick allows me to rip 1/4” off of a piece of lumber safely.

Hi Scott,
Would you be able to share a pic or diagram of the jig? Would greatly appreciate it.

The parallelism between then fence and the blade (and the riving knife) is not more than 0.005”. I have the blade guard on, which makes ripping narrow stock harder, but I still prefer to keep it on.

also if you are ripping if from a wider board the board can warp and move away from the fence causing that tapering

Nathan, I wouldn’t recommend wearing gloves in most woodworking (Cutting) operations. They can be caught up in blades and actually pull your fingers in worse. I know some do this all the time, but it scares me, especially with small pieces. Many warning labels on equipment says this.

Now, for the question. Probably look at blackcherry’s jig. Definitely some sort of jig should help. Search “jigs” under “Projects” for other ideas. Good luck

Generally, I agree with NathanAllen… it should be wide enough to have your safety features installed and still be able to get a push stick on it. I will sometimes go even narrower for small parts, but only if I can control the piece with my GRR-Ripper. A thin rip jig is always a safe way to go.

I agree with Charlie. I bought a pair of GRR-Ripper blocks and they are really nice when it comes to keeping fingers away from troublesome blades. They allow you to keep pressure (both vertical and lateral) during the cut at all times. You can also “hand-over-hand” for longer cuts. I have a really cruddy Craftsman contractor table saw with a fence that takes multiple measurements to get even close to ballpark. These blocks have saved me lots of frustration.

SH2005, here is a picture of the jig for ripping thin pieces of stock:

It consists of a face of thin material. In this case I use some 3/16” scrap with a 1/4” notch cut in the bottom and attached to a 3/4” piece of birch plywood that is the same width as my rip fence. On the back I put a tall piece of 3/4” plywood in case I ever needed to raise a panel on the table saw.

Here is the jig straddling the fence:

And here is the jig with a panel in it for demonstration purposes showing a 3/8” cut off the edge of the panel:

The jig could be improved by adding a dowel to the plywood that straddles the fence as a handle. I would recommend using the jig to rip thin pieces of stock between the blade and the fence but if you want to rip thin pieces of stock for inlays or banding then the jig that Charlie posted is the way to go.

When I was trying to make miter slot rails for my crosscut jig, I ran into the same problem.

If you Google “thin strip ripping jig” you can find LOTS of different concepts, too.

[EDIT: Here ’s one.]

I use the Grripper for rips down to ~1/4”. There’s an optional side leg you can get that is 1/8”, but I don’t have it.

Smaller than 1/4”, I just use a sacrificial push block that runs up against the fence. Just a piece of 2×4 with a piece of hardboard glued on the end to act as a hook. It’s actually not much different than the Grripper; just sacrificial. You can even stick some sandpaper on it for extra gripping. And really, it’s something you can reuse, if you want to keep it around.

Make sure you have a proper splitter or (better) riving knife to keep the cut side from wandering. It’s an essential safety feature when using these techniques. You have to guard against a random twitch getting you into a kickback situation. If you’re using a splitter and a sacrificial push block, make sure you have the blade high enough to clear the splitter. Not an issue if you’re using a riving knife, which is why they are better.

I think the main issue is to correct the fence if it is not parallel to the blade then use a gripper or push stick or ? can be used to feed the stock.

Thanks for all the responses. I am back working with my table saw now, was away for work for the last few days. I have seen the thin strip jig before and I am planning to make one soon.
Charlie, I like your design, it’s simple to make.
Scott, eventually I would like to make a jig like yours.
In the mean time, I am going to practice to see if I can pin point where the problem was coming from.

Actually, you can make the Strips sled from just a board with “Pusher” screwed behind….

I made one for long (67”) strips to cut 1/4” thick strips…and another, shorter one…

For very thin strips – 2mm (3/64”), I use the “Vacuum strips sled”

I personally like Niki’s method best… It keeps your appendages as far from the blade as possible without sacrificing control.
