By Wayne Peterson Understanding The Basics of Sandpaper
Selecting the best sandpaper for woodturning depends on understanding its core components. Sandpaper consists of abrasive particles bonded to a paper or cloth backing. The type of abrasive used plays a central role in how the sandpaper performs. The common types of abrasives are aluminum oxide and silicon carbide.
Aluminum oxide sandpaper is durable and a good choice for woodturning. It suits hard materials and can last through multiple uses. Silicon carbide, on the other hand, works well with softer materials and yields a finer finish.
The Importance of Grit Size
Grit size or the size of the abrasive particles is vital when selecting sandpaper. In essence, lower grit numbers mean larger particles, which remove more material. Higher grit numbers have smaller particles, which give a smoother finish.
For woodturning, you need a range of sandpaper grit sizes. Beginning your work with a lower grit such as 80 or 100 helps shape the wood. You then move progressively to higher grit sizes like 150, 220, or 320 to smooth the material before finishing.
Consider The Sandpaper Backing
The backing of the sandpaper is also a key factor to consider. Paper backing is common and allows for flexibility, fitting well into the contours of a woodworking project. Cloth backing, on the other hand, comes with enhanced durability. It can withstand the rigors of power sanding, something beneficial when refining curved or detailed woodturning pieces.
Deciding Between Dry and Wet Sanding
You also have to decide whether to dry sand or wet sand. Dry sanding is standard in woodturning, but wet sanding, using water-resistant sandpaper, can provide an exceptionally smooth finish. It reduces dust and prevents the sandpaper from clogging. Wet sanding requires silicon carbide sandpaper, which withstands the use of water, oil, or other lubricants.
The Value of Quality
It is worth investing in high-quality sandpaper. Cheaper sandpaper can mean inferior abrasives that break down quickly, inconsistent grit sizes, and poor bonding to the backing. All these factors can lead to disappointing results and wasted effort. Quality sandpaper lasts longer and provides uniform, reliable results.
Complement Sandpaper With Proper Sharpening
Alongside using the right sandpaper, ensure your lathe tools are kept sharp for best woodturning results. Consider using specialty systems like the Kodiak Sharpening System, designed to maintain the proficiency of your lathe tools. Quality sharpening systems play a pivotal role in producing high-standard woodturning pieces.
Final Words
Choosing the right sandpaper for woodturning is a combination of understanding the materials involved and catering to the requirements of your specific project. By considering the type of abrasive, grit size, sandpaper backing, dry or wet sanding, and quality standards, you can find the best sandpaper for your woodturning needs. And remember, complementing your efforts with sharp lathe tools will contribute significantly to outstanding results.
