Synopsis: Retired pilot Richard Babbitt has figured out how to harness the power of airflow to keep his workshop free from dust–specifically, to ensure that the dust from his contractor’s saw goes into the collector and not his lungs. By closing off most of the saw with wood panels and allowing air to flow rapidly through a few areas, he has managed to capture most of the dust from his tablesaw and keep the motor cool in the process. Intrigued with his ideas, two Fine Woodworking editors applied his principles to a hybrid saw and an old cabinet saw with equally impressive results.

As a retired pilot living in Washington State’s San Juan Islands, I often fly cancer patients to the mainland for treatment. Having witnessed the plight of these patients, I became earnestly motivated to minimize dust in my shop after the government categorized wood dust as a carcinogen.

The major dust maker was my contractor’s saw, one of an estimated million such saws in this country. Manufacturers seem to have given little or no thought to dust collection beyond sticking a dust port below the blade. The inefficiency of this system is obvious every time a piece of wood is cut and the operator becomes surrounded by a cloud of dust. To come up with a better solution, I put on my pilot’s cap and began to think about airflow. By applying aerodynamics to my tablesaw, I was able to vastly improve its dust collection, and keep the motor cooler in the process.

While I’ll focus on the contractor’s saw, the principles and techniques work on any saw. Two of Fine Woodworking’s editors will describe how they dust-proofed a hybrid saw and a cabinet saw.

Dust goes…
