Sandpaper Cutter




Introduction: Sandpaper Cutter

I'm 16 in Waco, Texas. I love being outside and building things, I can build anything with just a...

There isn't really an easy way to cut sandpaper, it dulls blades, and it's kind of awkward to rip. I have seen a couple of sandpaper cutters online using a saw blade, so I decided to make one.

Step 1: Materials

For this project I used:

- Saw Blade
- 1x7 Scraps
- Wood Glue
- Wood Filler
- 1/2x1 Scrap
- Parchment Paper
- Polyurethane
- Small Washers

Step 2: Creating Base

I wanted the base to be a square to ensure plenty of room, so I measured the size it should be by the length of the saw blade. I was able to use one length of 1x7, and one partial piece of 1x7 that had to be connected together. I then used pocket holes to connect the two boards. The top of the joint turned out smooth, but somehow the bottom of the joint had a very slight lip. So I filled all the cracks and imperfections with wood filler, and sanded it all down, giving a slight rounding on the edges and corners.

Step 3: Creating Fence

I used a piece of 1/2x1 scrap for the fence. I ripped it down in half and cut the length to size, and sanded it down flat. I then glued it down in place with wood glue in place against a speed square to ensure its squareness.

Step 4: Final Sanding and Marking for Blade

Once the glue was dry, I filled any cracks with wood filler, and sanded it all down smooth, also giving a slight rounding on edges. I also laid out the saw blade square where it would go and drilled small pilot holes to mark where it goes.

Step 5: Polyurethane and Ruler

After the sanding, I gave it all a polyurethane finish. I wanted to try out a new method I have heard of for the ruler. So I gave it a try, I printed the image out mirrored onto a sheet of parchment paper, and pressed it into place on the wood. It did kind of work, but didn't soak in enough. Maybe I didn't press it in enough, or couldn't soak in because of the polyurethane. Regardless I liked this method, and want to give it another try soon, maybe with a colored image. Since the numbers weren't dark enough, I went back and filled them in with sharpie.

Step 6: Finished

Lastly, I screwed on the saw blade with two small washers sitting under it. After that I gave it a test on some 220 grit, and it works. It takes a little practice to make a perfect cut, but overall, it works pretty well. I also added two small eye hooks for hanging. Thanks, and hope you enjoyed!

    Oh I see, I'll try that next time.

    Also set the printing to PHOTO. you get more ink on parchment paper just like photo paper.

    Maybe if you did the printing before putting on the polyurethane.

    Very nice! I was wondering if the saw blade could culd be a little tilted so that the side with teeth was closer to the base than the opposite non-cutting side then maybe it would cut better. Will surely give this a try. Nice work tough simple yet useful.

    Thanks for the tip, I like the idea of that.

    Good to see you're making progress with your passion for woodworking. Just a tip: record the date of build somewhere on the project, in years to come it will give you great joy to chart your journey and the milestones you have reached. Later, when you get old, like me, you'll even write down just what the heck the jig is used for- more jigs and fixtures than one can recall. ;-)
