soapbarstrat Posted February 2, 2004 Report Share Posted February 2, 2004 I need a "tool" that doesn't exist. Problem is ,I tear off pieces of sandpaper and often tear off the exact part that has the grit number, then later I have to study the piece with no number on it, to try to figure out what grit it is. It would be nice to have a little device, I could slide a piece of sandpaper in, and it would tell me what grit it is. Snork, get to work on this Or, if the the darn sandpaper companies would print the grit size smaller and reapeatedly all over the back of the sandpaper. Takes a lot of time to do somthing like that myself with a pen. Quote Link to comment Share on other sites More sharing options...
LGM Guitars Posted February 2, 2004 Report Share Posted February 2, 2004 Well, I just have a rack that all my grits sit in, and I make sure to only have one grit out at a time, then it goes back into that rack when I'm done with it. The ones that bug me are the discs I use on my random orbit, they don't have the grit printed at all, so you have to keep them organized right from the store which is great until the clerk tosses them all in the bag without keeping them separated.

Brian Posted February 2, 2004 Report Share Posted February 2, 2004 I just wish the Canadians would start producing 800 grit again! In case you people didn't know 3M sandpaper is made in Canada.. Quote Link to comment Share on other sites More sharing options...

Ha ! You think I could ever get THAT organized ? I should take photos of how "organized" my tools and supplies are. Sandpaper gets thrown into the 'sandpaper' drawer, where it gets to party down with all the other grits. One big happy abrasive orgy goin' on in that drawer, I have to assume.

That'swhat I do. I have like this file folder thing, you can probably get them at business stores, I mark each folder section with a grit number, and put each grit back in place once I'm finished. I used to do what soapbarstrat does, but it got out of hand. Quote Link to comment Share on other sites More sharing options...
JPL Posted February 2, 2004 Report Share Posted February 2, 2004 I use a folding file too. I might be paranoid but I don't like the thought of cross contaminating grits. My invention for keeping track of what grit I have is a Sharpie. Low tech works for me. Quote Link to comment Share on other sites More sharing options...
Jon Bell Posted February 2, 2004 Report Share Posted February 2, 2004 If I rip the sandpaper into smaller parts I write what grade it is in pencil on that back. Simple but it works for me. Quote Link to comment Share on other sites More sharing options...
Morben Guitars Posted February 3, 2004 Report Share Posted February 3, 2004 Get a few different colors of permanent marker, then assign a color to each grit. Now all you have to do is draw some hash marks on all your paper (before you rip it up) and any piece you tear off will already be marked. You'll memorize your colors in about a week, or just keep a small cheat sheet nearby. Quote Link to comment Share on other sites More sharing options...
soapbarstrat Posted February 3, 2004 Author Report Share Posted February 3, 2004 Awwwww come on, I want that machine. Don't we have at least one Homer Simpson type who can try to build this machine in his garage ? I figure if they have machines that read finger-prints, they should be able to have one that can read abrasive grit size and amount. I do sometimes write it on the paper, but just my luck I end up tearing just that part too before i realize it. Quote Link to comment Share on other sites More sharing options...
renablistic Posted February 3, 2004 Report Share Posted February 3, 2004 The device would be impossible. When you use sandpaper you automatically begin to wear down and take off paricles, therefore a particle measurer and particle counter wouldn't work. Also, only grits that are like 600 or higher have a uniform grit, where there is the same amount of particles in the same concentration for every square milimeter. The lower grit is more like: "ya throw some glue and sand on there, whatever" And brian, I have like 5 sheets of 800, i love the stuff, not too rough, not too fine, good for taking off small bits of wood atta time. You guys are losers! I mean come on! You can usually tell the grits apart by colors. The lowere grits like 80 are allways brown, and etc. Also, just train your fingers. Maybe it's because i have sensitive fingers, but i can tell 1200 from 2000 or 80 from 100 any day just by feel. Quote Link to comment Share on other sites More sharing options...
Southpa Posted February 3, 2004 Report Share Posted February 3, 2004 I just finished sorting out all my sandpaper from my last project. I can pretty much tell what it is by the feel, I have lots of sanding experience, except for the real fine grits like 1200 and up. I'm not sure exact grit numbers are all that important, all you really need is coarse, medium, fine and REAL fine, . Hell, a blind man can do it!

skibum5545 Posted February 6, 2004 Report Share Posted February 6, 2004 And he can even tell you what dirty jokes they printed on the paper in braille Though I hate saying this, I really did do it: LOL All I have is 3 big folders (my dad bought the sandpaper in bulk about 20 years ago, its older than I am) of 120, 220, and 600. It's all we need. Eventually, I will buy some 1500 or 2000, but again, just keep track by box and look. Quote Link to comment Share on other sites More sharing options...
soapbarstrat Posted February 6, 2004 Author Report Share Posted February 6, 2004 Seems that Brian Galloup goes from 320 grit to 600 grit, then 1000 grit. That'll save on some sandpaper. Can't imagine life without 400 grit around, tho. Seems like there's always been some of that around my whole life. What I want now is DIAMOND "SANDPAPER" Quote Link to comment Share on other sites More sharing options...
CaptMysterio Posted February 7, 2004 Report Share Posted February 7, 2004 norton abrasives still makes 800 in waterproof sheets for automotive refinish applications. i'm not sure if it'll fit for your application, but it's out there.

Davis guitars Posted May 26, 2006 Report Share Posted May 26, 2006 could just write what grit it is on the back with a sharpie Quote Link to comment Share on other sites More sharing options...
Jalien21 Posted May 26, 2006 Report Share Posted May 26, 2006 man, i'm with the "feelies" on this one. i find that sandpaper will sort of change what grit it acts like the more you use it. a 120 will get duller and start working like a 220 fir a while. so i keep most of my sandpaper around until i gets destroyed. i just sort of feel for a piece that has about the right scratchiness to it for what i want to do. that dosen't really work too well above like 400 because up there it all feels the same to me, but i just tend toward whatever feels like it would work right Quote Link to comment Share on other sites More sharing options...
Mattia Posted May 26, 2006 Report Share Posted May 26, 2006 (edited) Eesh. Talk about reviving 2.3 year old threads, guys... (I just buy stuff that's labled, obvious, keep it seperated, chuck it out when it stops doing what I want it to; I don't want dull paper cutting like 'higher grit' paper, I want sharp higher grit paper doing its job properly.)

Setch Posted May 26, 2006 Report Share Posted May 26, 2006 The problem with using old paper is that it doesn't actually get finer at all. It gets duller, so it cuts less efficiently (so it cut at the same speed as a finer paper), but it still leaves the same size scratches behind. So you're doing more work, to get an inferior result - IMO a poor move Fresh paper, toss it as soon as it starts to get dull. I'm afraid my organisational system follows soapbars abrasive orgy model... Quote Link to comment Share on other sites More sharing options...
erikbojerik Posted May 26, 2006 Report Share Posted May 26, 2006 Use enough sandpaper, and eventually you'll be able to tell just by looking & feeling. Quote Link to comment Share on other sites More sharing options...
Setch Posted May 26, 2006 Report Share Posted May 26, 2006 I can tell 320 from 400, but if you handed me a slightly broken in piece of 400, 600 or 800 grit I wouldn't be able to tell you what it was. Not with the 3m gold frecut anyway - they all feel like slightly aggressive peach fuzz! Quote Link to comment Share on other sites More sharing options...
Guitarfrenzy Posted May 28, 2006 Report Share Posted May 28, 2006 Man, it's totally ironic that this subject was brought back up. I was just putting the final touches on my SandScope© Machine, and have a patent pending right now. Let me further explain what this machine will do for you!!! - Scans sandpaper and determines the actual grit, even if it's been used before!!! - Can alter the sandpaper to whatever grit you want. Example: You have a 100grit sandpaper and want 600 grit, run it through the patent pending SandScope© Machine, and VOILA, you now have the desired grit!! - Will analyze your sandpaper and give you valuable specs on it. Like the following: date it was made, what materials was used to make it, and also, estimated usage time of the sandpaper. I know it's hard to believe guys, but it's coming sooner than you think!!! Robert, you are going to order one right? I did devote 2.3 years of my life trying to solve this thread. disclaimer: The above statements are for entertainment value only, and the SandScope© is not real product, but a product of my imagination. Please don't call or email me about this device, unless of course you believe anything you hear, and have a lot of money. haha Quote Link to comment Share on other sites More sharing options...
