I recently made some hand sanding blocks that take 1/4 sheet of sandpaper.

I also replaced my Ryobi 1/3rd sheet sander with a Makita 1/4 sheet sander so I needed a good way to cut up sandpaper to fit both.
I saw several clever designs for guiding a knife, but they involved cutting many MDF blocks to exact sizes and anyway I don’t like using a knife on sandpaper. I almost built a design using a hacksaw blade and a clever flip up stop to allow cutting the different sizes using only one blade. However, hacksaw blades come in packs of 3 for less than 50 cents so I made this simple effort using 2 blades.
It works well. So does the Makita sander, I have never been so glad to replace a tool, the Ryobi sander was dreadful.

Hey Mark, nice handy cutter! I also replaced my Craftsman1/3 sheet sander with a 1/4 sheet sander. i threw the 1/3 sheet sander away. I could do better with a sanding block!

I have used a similar cutter for years. It works great. I did put a strip of wood over the saw blade to lessen flexing of the steel blade. You will use this a lot. I have a porter cable speed block and I go through a lot of paper.

-- Robert, so much inspiration here, and so little time!

The sanding blocks come from an old Wood magazine. The plan is online but I got mine from one of their compilation blocks of shop tips and projects.

Wow, that looks like a very handy, and simple design. Hope you don’t mind me using it. I put it in favorites along with the blocks. Thanks for posting them.
