how to choose the right sandpaper grit and type - bob vila

If youve ever worked with wood, youre likely familiar with instructions to sand all edges after cutting: before applying a finish, between coats of paint, and so on. Seeing sandpaper on a tools and materials list may seem easy enough to check offuntil you hit the hardware store and face stacks of sheets and booklets, each distinctly identified with a different set of numbers, or sandpaper grits. Which did this project call for again?

Different sandpaper grits perform very different jobs, and selecting the right grit can be confusing when youre starting out. Warm up with these basic recommendations and rules of thumb. This guide will run you through:

Sandpaper isnt made of sand, of course, but rather it consists of fine particles from either natural or synthetic sources. The particles (also known as grains or grit) are sifted through screens and sorted by size before being bonded with adhesive to a paper, sponge, or cloth-type backing to create an abrasive material thats handy in a number of do-it-yourself situations.

In the United States, grit is determined based on a gradation scale established by the Coated Abrasive Manufacturers Institute (CAMI). When shopping for sandpaper, youll see numbers such as 80-grit, 100-grit, or 200-grit. Keep in mind:

On the CAMI scale, sandpaper grit is measured in microns, and to get an idea of how small a micron is, check out a piece of 100-grit sandpaper. The small grains on the sandpaper measure approximately 141 microns in size, which is equivalent to .00550 of an inch. Very small.

Most sandpaper you buy at DIY centers and lumberyards will bear the CAMI scale, but if you order sandpaper online, you may run across sandpaper grit sized by the Federation of European Producers of Abrasives (FEPA). Grit sized with the FEPA scale is indicated by the letter P preceding the grit number. While there are too many grit gradations to list, if youre buying FEPA-sized sandpaper, the following commonly used CAMI sizes will give you an idea of the corresponding FEPA sizes. FEPA sizes are not an identical match to CAMI sizes, but you can get something very close by selecting one of the two closest FEPA numbers.

To make choosing sandpaper easier, manufacturers identify a coarseness level in words on the package in addition to the specific grade. This is essentially a range of grit sizes that are similarly effective for the same sanding work. In fact, its not uncommon for projects to call for a certain coarseness level as opposed to a specific grit of sandpaper, so its smart to know what each level includes.

Not only does the density of sandpaper grit make a difference in the success of your sanding project, but the type of abrasive material does, too. Some types of grit grain are better suited to smooth and sand types of materials (wood versus metal, for example). Most manufacturers list the type of material best suited for sanding on their product labels, but its smart to know what type of grit to look for before you shop.

Sandpaper is very versatile by itself: You can fold a sheet into a palm-sized square, sand until the grit dulls, and then refold it for a fresh sanding surface. If you have a lot to sand, however, you may be better off making use of one or more popular sanding tools. Even with these instruments, choosing the right sandpaper grit and type for the job still applies.

Making clothes appear vintage and worn is an ongoing trend that flits in and out of mainstream and indie fashion. Clothing that is made to look vintage and worn can be very expensive. Luckily, it is easy to make your clothing look this way using supplies from around your home. All it takes is a little bit of time and creativity. Best of all, you will get the exact look you want while saving money and looking fly!

To make clothes look vintage and worn, use a razor blade to cut small nicks into the hem or collar of a t-shirt or into the waistband, cuffs, or knees of a pair of pants. After cutting or tearing, wash clothing as usual to soften the edges and make it look more natural. You can also use sandpaper to distress hems, cuffs, and knees or to fade prints. For an overall faded look, submerge clothes in a water and bleach solution for 5-10 minutes, rinse, and wash as usual. For tips on how to use coffee beans or lemon juice to fade your clothes, keep reading! Did this summary help you?YesNo

in the news: with machine learning, manufacturing giant 3m innovates products old and new | aws for industries

IN 1916, the Minnesota Mining and Manufacturing Company, or 3M, opened its first research lab, a closet-sized space in its St. Paul sandpaper factory. A series of incidents across the first 14 years of the companys existenceone involving a shipment of sandpaper botched in transit by a spilled case of olive oil revealing the papers poor qualityinspired the then general manager, William McKnight, to create a space for testing products to improve quality control. As McKnights influence grew (he would become chairman of 3Ms board in 1949), so did the fervor for quality. Over the years at 3M, entrepreneurial scientists transformed everything from wild ideas to incidents like the sandpaper shipment to even failed experiments into products that are now household staples, such as Scotch tape and Post-it notes.

Quality remains an intrinsic facet of the culture at 3M. Spurred by the success at the lab, 3M has significantly expanded its research facilities. Nearly six percent of the companys revenue is now funneled into R&D. In St. Paulwhere nearly 12,000 employees come together to create and launch new products and improve old onesthousands of researchers and scientists in the corporate labs are striving to add to the innovation pipeline.

One of the most important topics on the 3M campus is machine learning. Using machine learning on Amazon Web Services (AWS), 3M is improving tried-and-tested products, like sandpaper, and driving innovation in new fields, like healthcare. Perhaps as a testament to the programs effectiveness, products that are less than five years oldconsistently contributeto about 30 percent of the companys revenue; every year 3M releases about1,000 new products.

There are not many companies that can combine what we have as a rich material foundation with the digital capability to really make something new, said Hung Brown Ton, Chief Architect at the St. Paul Corporate Research Systems Lab. Thats whats exciting for usleveraging these new cloud capabilities like machine learning.

Since overcoming countless sandpaper-making hurdles of the companys early days, 3M has continued to improve the abrasive capacity of its long-standing product. Until the recent introduction of machine learning techniques into the product development workflow, however, the process was extremely time-consuming.

The ideal grain of sand (which is actually a synthetic material called Cubitron) cuts best and lasts longest. Traditionally, to arrive at that ideal, a 3M technician would inspect a CT scan for each sheet of paper to assess the number of grains on a sheet. Then, the technician would test each sample against a rough surface to measure its effectiveness and try to correlate that effectiveness with the percentage of grains.

This involves a long development process, which takes weeks, said Brown Ton, as he and his team collaborate with research scientists who are developing the new abrasive samples and products (including the product still colloquially referred to as sandpaper).

With machine learning on AWS, which Brown Tons teams started implementing a little less than a year ago, the process is now much faster and more precise. The 3M team is currently testing models that use traditional image training as well as leveraging neural networks on Amazons SageMaker. While the technician still tests the samples, the models make image analyses significantly faster, helping her narrow down the best options. These machine learning models enable researchers to analyze how slight changes in shape, size, and orientation may improve abrasiveness and durability. In turn, those suggestions inform the manufacturing process.

Given the amount of data generated by these scans and tests (about 750 GB per palm-sized sheet), the team was initially blowing through the heavy-duty engineering laptops it had bought to run the analyses. So it made perfect sense to move this capability to the cloud, said Brown Ton, because we were enormously hampered by the compute power of any conventional laptop or desktop we could purchase. The process today in AWS is orders of magnitude more efficient and a delight to spend our time on understanding abrasives instead of waiting for data to be collected and tests to complete.

While sandpaper is a 3M staple, as the manufacturing company has grown, it has expanded into new areasincluding healthcare. 3M founded its subsidiary Health Information Systems (HIS) in 1983, not long after the first major electronic health record (EHR) system was developed. Today,96 percentof hospitals are using EHRs, compared to just a sliver ten years ago, and in all that data HIS saw an opportunity to build something new: a set of machine learning-powered medical coding products.

In order to charge insurance providers for its services, a healthcare provider must translate EHRs into the appropriate billing codes. Errors in the process are common, and can result in delayed payments or over-billing, which is fraud. In the U.S., most hospitals are managing it with the help of HISs Natural Language Processing (NLP) tools, which are powered by machine learning on AWS.

David Frazee, the research labs director and a 14-year 3M veteran, was previously HISs CTO. He said the traditional process of determining billing codes required that individuals known as coders review each record and, based on knowledge and experience, pick the right code from one of literally141,000options. Three weeks later, you could give the same coder the exact same records, and they may determine a different code, said Frazee.

Since April 2016, HIS has combined that imperfect human expertise with machine learning models to reduce the error in the process. Much of an EHR is unstructuredas Frazee puts it, anything beyond a doctors scribble on a napkin probably qualifies as a recordso simply getting the models to understand what a record means is a feat.

To that end, linguists teach the NLP model to parse confusing recordsfor example, to know that a doctors note describing a body part as cold does not mean the patient has a cold. The coders sign off (or dont) on the models decision. Their evaluation is fed back to the model, so it can improve the next round. The model, which processes a staggering three million documents daily, is learning quickly, and in many procedures selects the right code about 98 percent of the time. The model itself runs on high-powered Amazon EC2 and S3 instances.

The abrasives R&D project is, I think, very representative of the future of 3Ms material science and data science collision, Frazee says. We are one of the best materials manufacturing companies in the world, but we have not taken advantage of the fact that weve got a lot of data about our materials.

And if you think about the data being aggregated in the cloud, collected through IoT, processed through machine learningwhile also leveraging modeling and simulation and the ability to visualize vast amounts of dataall these things come together for us, Brown Ton adds. Continuing to leverage these new and rapidly evolving cloud capabilities is really exciting for us and our customers.
