Table Saw Accessorizing

I made up a jig out of a magazine recently for my table saw. It’s a simple, but effective miter extender. I put forth the unnecessary effort of adding a spline joint to the design (using padauk as the spline material). I did it because the glued butt joint called for looked weak. What I didn’t realize until later was that the article said to note grain direction on this part to insure that your were not gluing end grain. I didn’t note grain direction – something I really need to pay more attention to. When I read this part later, I realized that my spline joint was ineffective as a strengthening measure because it was glued to end grain on one piece and long grain on the other. Of course, in a piece such as a marking slide on your table saw jig, this matters very little. It will not likely encounter the force to break it unless it gets dropped or something. So in the end, I added a pretty red spline for aesthetics and a learning experience. Oh well.

The project was made using magnolia for the length, sycamore for the stop-block, and padauk for the spline.

It is good to have a stop on the miter fence for repeatable cuts.

This is a handy device,thanks for the tip!
But I think you are being too hard on yourself.I agree that edge grain would have been a better gluing surface but the spline adds a lot of strength to this type of joint regardless of grain direction.Plus it just looks nice.

Nice looking extender. Mine is much uglier. I need to spend more time on such things, they are a joy to use.

I guess that is a home made T-Track? If so, did you use a keyhole/picture_hanger type router bit?

Chill over the spline, but I guess it is a ‘note to self’ to watch out for this situation in the future. You could always add a dowl or two at this point if you are worried.

Good looking miter fence. Should come in handy.

I used the table saw and I could have used this with greater accuraticy and safer use. Nice I idea thank for sharing.

@SPalm: It is a homemade T-Track. I didn’t have the bit you’re talking about, so I made it with the table saw. I find changing bits on my router frustrating, so I tend to look for other options. In this case, I made the fence from two pieces of wood glue-laminated together. I cut the bottom of the T-Track with a single (non-through) table saw cut down the length of my wood. I then cut the wood in half lengthwise. With a waxed-spline inserted into the matching kerf cuts, I was able to glue the two halves together to make the fence you see pictured. After the glue dried, I merely tapped the waxed spline with a hammer and pulled it out of the groove. In case you’re unfamiliar with this process, it’s done to keep the kerfs aligned perfectly during the glue up. I then used the table saw to cut out the track run. I don’t have a dado blade, so I just cut it twice to dislodge the piece floating over the spline cut. It takes some careful measuring to ensure your resulting cuts will leave a run in the track slightly larger than your bolt. I posted about some problems I had in this process here. The beauty in doing this part on the table saw is that you only have to measure once (or twice in one place, anyway). When using a rip fence on the table saw, you can quickly center cuts like this by simply flipping the board over and repeating the cut on the other side of your board. It’s probably common knowledge, but I suspect that some people forget the simple stuff and lose time to “second guesses.”

Great jig Olaf. Even though you have had some problems it will still be a very handy accessory.

Nicely Done. You should check out TomFrans extension poster a few days ago. I like how he used sandpaper. Worth a shot.

I really like this project. I’m intrigued by the use of magnolia. Is this readily available? I’ve been looking around but can’t find any suppliers on the internet. nice work.

It’s not real common, even in northeast Georgia where the trees are. I’m not exactly sure why you don’t see more of it, but I can say the trees have to be fairly large. With the branches arranged around the trunk its entire length, it can very knotty. Mine is practically void, but I picked the boards that way.

It’s been a long time since I built this jig and it’s still serving its purpose in the shop! That splined butt-joint is still holding strong. The wood has aged nicely as well. The only thing I could have done better here is to have made the fence longer. It seems like so many times that it’s just an inch short. In reality, I’ll probably just add a sled jig to the table saw instead.
