In my never ending pursuit of better organization for my hobbies.
Fits a 4x3 grid, there is a knife guide under the numbers that allows for cutting the paper into 9 even pieces.

Looks great! I did a really similar one - I cut my 9x11 sheets into a 1x3 strips and store them in a 3D printed holder that hangs on my pegboard. It's been great.
 
Ooh that's a great idea. I just ordered a ton of new silicon carbide sandpaper and this looks like a great way to keep a working supply organized. Thanks for the tip! I've been using gridfinity rugged stackers and some of the regular bins to organize blanks and pigment samples. It's such a great system.
 
Nice idea. I'm getting to the end of my multiple rolls of penturning sandpaper, 150-600 grit. Thinking of buying sheets and cutting them to widths for pens and other turnings.

I have posted a few gridfinity projects I have done. I am a big fan of gridfinity.

I recommend the 3m "wetordry" sandpaper it's a good price and good quality.

After doing a deep dive on sandpaper earlier this week, I found this site recommended in another thread here, which has pretty great prices: https://www.onlineindustrialsupply.com/wapa.html

For some reason the Norton 800 grit was only in Aluminum Oxide, so I went with the BlackCarbon (in house?) brand for that grit. I picked up 400, 600, 800, 1200, 50 sheets each for around $130 shipped. I have used 3m wetordry and I'm curious how it will compare.

Interesting….. 3M has been my go to for almost 20 years. (thanks to my dad) That stuff looks interesting as an option. Right now I'm working on developing a non water lubricant for sanding.

I'll let you know how it goes. I was running low and picked up something locally and it was giving me single deep grooves so I just bit the bullet and did a bulk order. I've seen Norton recommended here a few times, and did a deeper dive on other high quality papers, but I could only find them for around $90 per grit which seemed maybe better for a future experiment.

10 sheets of 3m is running me less than $9 at my local Home Depot. It's hard for me to justify "high end" paper. At some point you are paying for the brand and not the ability of the product.

For sure. That's why I tried these out. It was 50 sheets for $32. One of the things I was looking at was Mirka WPF Pro, which says it uses resin on resin bonding and latex paper. I have no idea if this would make a difference or be worth it, and I'd like to try it someday just out of curiosity, but it was pricey.

That's not a bad price! 3m says that they use a resin as well. I will say that I won't use a "glued paper" for wood working. I have seen it get hot and degrade into the project I'm working on. Yes, I was pushing it to hard and what not. I have not seen that happen on the "resin" paper. Gives me more room to force it if I want to.

I looked at the Norton page again and it says resin bonding and waterproof flexible paper also, so likely all similar stuff. You're probably right that the Mirka is overpriced.

Looking into it a little more. It's all in the bulk pricing. I'm seeing Mirka WPF Pro at a better price than 3m. If you buy the equivalent of 15 packs of 3m from HD, Mirka WPF Pro is cheaper.

Ah yeah I should have said higher entry point as I couldn't find any quantities in the price point I bought at. But I was also researching pretty late at night. In any case, I'm sure the Norton will be fine.
