1/4 Sheet Sandpaper Cutting Jig

Project by Hawgnutz posted 427 days ago 982 views 6 times favorited 11 comments Add to Favorites Watch

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,
Hawg

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

Cheers

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,
Hawg

I made a jig that’s a similar idea, but uses a hacksaw blade screwed to the base. No knife needed, simply slide the paper under the blade, line up the paper to marks and tear. There are marks for the long and short sides of 1/4, 1/3, 1/6, as well as 1/2 sheet.
