Every consummate woodworker depends on well equipped drum sanders to complete sanding jobs to perfection. Power sanders are far superior to manual sanders to help you finish wood pieces that need to be sanded. They are infinitely much quicker, easier and more effective.
The decision to buy a drum sander depends entirely on the type of project on hand. If working within a workshop then a stationary sander is best. There are a variety of stationary sanders and some are quite affordable. Besides being very convenient, they are stable, cutting down on vibration and noise.
For projects outside of the workshop, you should go for portable sanders that are good for finishing projects. For flooring jobs you would need to buy a portable belt sander and for finer jobs like on staircase banisters you'll need to invest in a small random-orbit sander.
Features to consider while purchasing drum sanders would include ergonomics, noise factor, vibration control, sandpaper attachability, dust collection and size. This would obviously depend on the nature of the task you are undertaking.
Finally pricing is the all-too-important factor for buying these expensive appliances. Hand-held sanders are quite a bit less expensive than the stationary sanding machines.
