How to Build a Sanding Table How to Build a Sanding Table

A sanding table can be a useful tool for collecting the sawdust that comes from sanding pieces of the wood working project or even collecting dust in the workshop. A sanding table can be as small as s table top unit or large enough to be a table itself.  This article will provide the key features of a sanding table, where the unit can be built as large as needed.

Type of Table

A sanding table can be built out of a box with any wood materials which happen to be available Most of the sanding tables have a similar design. There is the sanding surface, perforated so that the dust goes into the holes, a box with doors or drawers to allow for emptying the dust, and a method of creating a vacuum for drawing in the dust through table top. Below the top can be the guides which allow the dust to drop down to the collection area. The collection area is an enclosed part where dust is collected in the space or a bag can be supplied to collect the dust for easy retrieval. A search of the internet yields several references to plans for a sanding table

The Sanding surface

In order to be an effective sanding surface, holes will be needed to allow the vacuum action to draw the dust from the sanding area into the table to be collected. The over all surface of the table can be as small one square foot to whatever size may be needed. The caveat would be that the larger the surface area of the table top, the more holes will be on the top to draw in the dust. Vacuum requirements will increase with the size of the table. Most sanding surfaces will need to in the range of four feet or so to allow for sanding of larger pieces of wood. The filters can simple air filters such as those used for air-conditioning or a dust collection bag similar to those used in a vacuum.

Dust Filters and Vacuum

Filtration will be needed to keep the dust out of the vacuum and maintain suction to draw in the dust. Some smaller tables are supplied with an outlet where the suction hoses from a central dust collection system are used to create the vacuum to draw in the dust. A fan in an enclosed area with air filters can also supply a vacuum where sanding dust can be drawn in and collected.

Dust collection

Dust collection is supplied by either the central dust collection system or in the table itself. The table should be built so that the air used to draw in the dust is filtered but the dust can fall into the bin where the filters are so that it can be collected and emptied once in a while. If the vacuum is supplied by the central dust collection system, there may not be a dust collection area for the table as the dust will be stored in the central vacuum.
