Not all your woodworking projects are about straight lines and sharp edges. Sometimes you need to sand round, strangely-angled, curvy furniture, and your belt sander just won't cut it - figuratively and literally! 

That's when you fire up your oscillating spindle sander.

A spindle sander is a small cylindrical drum covered with sandpaper, mounted on a worktable. It rotates at high speed and produces smooth round or curved edges. It's also the only kind of sander for the insides of deep hollow cuts.

In this article we'll recommend 8 great products that you can buy, outlining their pros and cons. That'll be followed by a buying guide and some tips and tricks.

Happy sanding!

How to Choose an Oscillating Spindle Sander

With so many brands and models on the market, getting the best oscillating spindle sander for your needs can be challenging. Here are the key things to look out for when buying one.

Motor Power

This should be the first thing to you check before picking a model. The more powerful the motor is, the better and quicker you can work. Personally I'd always choose one with at least 3.5 amp motor but your needs may vary.

Accompanying Accessories

Accessories determine a sander's use and convenience. Some models come with multiple sanding sleeve sizes and rubber drum spindles. On-board storage for the accessories is great to have and worth paying a little extra for.

Dust Collection

A dust port is essential. Choose one that is compatible with the dust collector system at your workstation.

Work table

Choose a large worktable that provides enough space for the largest project you're likely to undertake.

Additionally, make sure the construction is solid. A cast iron worktable is your best bet.

Brand

This slightly comes down to experience and personal preference, but when it comes to dangerous equipment I no longer go for no-name products. Give me a Wen, Triton, Grizzly and I'll pay an extra few bucks without blinking.

Noise Rating

Just like other power tools, spindle sanders produce noise. Of course you should always wear ear protection but if you're looking at two similar models and one is 89 decibels and the other is 95, your family and neighbors will thank you for buying the former.

Tips and Tricks for Using Oscillating Spindle Sander

This is one of the easiest woodworking tools to use. Like any other power tool, however, you can enhance the performance of your sander by following recommended procedures and guidelines.

Here are some of the tips to help you use your sander optimally:

  • Safety: Your safety is always the first thing you need to consider when using an oscillating spindle sander. Make sure you are conversant with the safety mechanism of the sander and avoid wearing long sleeve and baggy shirts when operating the machine. Also always wear safety googles.

  • Use a fluid, natural motion: Never force your wooden piece into the spindle. This can ruin its surface. You should always start from one end and then move it slowly through the spindle in one fluid wave.

  • Measurements decide the level of precision: A sander's precision is only as good as the measurements you make. As such, mark your measurements accurately with a pencil.

  • Move quickly and fairly on long curves: It is important to move quickly and make several passes when sanding long curves. When you do this, you will be sure to keep a smooth line while eliminating all your sanding marks.

  • Sand to the line: Make sure you sand to the line you have measured and marked with a pencil and not until it vanishes. If you sand the whole mark, you will be over-sanding.

Conclusion

Oscillating spindle sanders make it easy for you to sand curved or round surfaces that might be cumbersome to sand with the common belt and disc sanders.

They also comes in handy when working with odd angles. As such, if you are working on these kinds of materials, you need to get an oscillating spindle sander that is best for your needs.

The buying guide above should direct you on how to choose the right spindle sander to add to your workshop.
