1/4 Sheet Sandpaper Cutting Jig

Here is a real simple jig that makes cutting sandpaper for 1/4 sheet sanders a breeze. It is simply a 8 1/2” X 11” piece of 1/2” MDF that is mounted on some scrap plywood and surrounded by 1X stock. (You really don’t need to miter the corners, just butt up the two pieces of wood.) Then grooves were cut with a table saw where you would cut the sandpaper. This allows you to easily cut the sandpaper to the correct size using a razor knife. I also added a piece of luan to act as a hanger on the back.

I am planning to make one on the back that will allow me to cut 1/3 sheets for my sanding block. You can see I am getting ready for my finishing sanding..LOL

God Bless,

I nailed a hacksaw blade on a chunk of plywood several years ago.
I just slip the paper under the blade and pull up.

A very useful jig and a great idea. I also like the Bob #2’s concept.

I usually take a few minutes to do 5 sheets at a time and 1/3 them for a stock pile but this idea would certainly speed that process up.

Thanks for the post.

Made one of the yesterday and already have gone 5 sheets of paper. Making/having this motivated me to get my Adirondack chairs sanded and ready for staining. Was this your original idea of did you see it somewhere?

Thanks for the post

Tmiller, this was a modification of a basic sheet cutter I saw somewhere. You knmow how it is, you see some projesct or jig and you think, “I could chsnge this and it would be better.” Well, I saw one like this in a book and modified it to conform to how i wanted it to work. This works great for my PC 330 and my 1/4 sheet sander!

I am going to make a 1/3 sheet cutter on the other side to fit my hand sander.

God Bless,

I like this. Could you cut slots for other paper sizes on the same template?

Yes, Russ, you could cut slots for just about any size paper. In fact, I am going to make one to fit my 1/3 sheet sander on the back side, so I could just flip it over and cut the 1/3 sheets.

You are only limited by your imagination, here!

Thanks Hawgnutz,
What I was saying though was just putting all the lines on the same template on the same side. The quarter sheet lines would be obvious and distinct from the one third sheet lines, so there would be no confusion. I got waylaid today or else I would have made one myself. This is a really useful idea. Too often I find myself eyeballing when I have no straightedge, but this solves the problem.

Thanks again, Hawgnutz.

Thanks again Hawgnutz,
Finished making mine a couple of hours ago and it has come handy already. I put all the lines on same side. I put the lines for quarter sheets two ways: half in each direction, as well as the 2 3/4 inch increments for my sanding blocks. I added the 3 5/8 inch lines for one third sheet sanders, too. Thanks once more for a great time saver.
