I’ve been meaning to make this for awhile but just haven’t got around to it. Decided awhile back that I liked the ShopNotes version

Purchased the bearing a couple of months ago. Had difficulty finding a bushing to fit inside the bearing.

So I had the brilliant idea of just shoving a 5/8” dowel inside. This would allow me to then drill a 1/4” diameter hole for the 1/4-20 bolt. Problem was finding the exact center of that little 5/8” diameter piece. The first version looked pretty good but once I placed the bolt and spun the bearing the slight offset became evident. Tries two and three didn’t work either. So back to 9th grade algebra. Actually, I failed that class as missed so many classes thanks to a broken clavicle that I really fell behind. So off to google. As an adult, it was so much easier to understand how to find the center of a circle by drawing 3 cords and the subsequent perpendicular lines. Here's the formula.

One of the things that I discovered as that despite cutting the top and bottom pieces to the exact sizes on the plans, it only gave me 7/16” room between the blade and bearing surface. Doesn’t give me many options for ripping thin strips. In order to gain more room, I simply shortened the bottom piece length so that there is 1” between blade and bearing.

I needed a reference scale and happened to have an extra Incra scale that I had chopped short for my crosscut sled. While it starts at 40” versus 0”, I know what I’m looking at despite that big ole #4 LOL.

Overall I’m super happy with the end result. After zeroing the scale by placing the bearing to the saw blade (left most teeth) I set it for a 1/6” cut. As you can see, that’s EXACTLY what I ended up with.

Nice looking thin strip tool. I am going have to build one for myself!

I like the hairline/ruler you added.

Just a 1” x 1-1/2” piece of acrylic and a sharp utility knife for the hairline.

Thanks for posting your jig. It looks really sharp and something I might want to copy.

I made one of these years ago. I made a spring loaded attachment that slips over the nose bearing to use it as a featherboard.

This is the bottom you can see how the featherboard arm works.

Nice idea. As a newcomer to the woodworking arena, I have to ask. Why is this preferred over cutting thin strips on the fence side? Assuming, of course, that there is a sacrificial piece of wood between the fence and the strip.

Pointer. Trying to rip 1/2” and smaller becomes difficult and unsafe. This way, one can still use their pushblock between the blade and fence without putting their hand close to the blade. That is until the stock because to thin to work with.

Because the thin strip, trapped by the fence will catch the blade and get flung back at you like a javalan.

Pointer.

No problem. If you can, build this. It’s good practice. Grooves, 45 degree angles, drilling, etc.
