Sandblasting

Sandblasting Precision Board HDU uses the same techniques as when blasting any lightweight wood. HDU is made up of millions of tiny cells so blasting is much easier and the sandblaster can get much closer to the work surface. Since HDU doesn't have any grain, it is important to set the air pressure to about 40-60 psi at the pot. This reduced pressure still allows for fast blasting and subtle detail can be created during the process. The blasting medium, or grit, should be either aluminum oxide or medium grit silica sand.

Carving

Carving HDU is almost the same as carving wood but it is much faster and easier. The same types of chisels, knives, and other surfacing tools can be used. It is easier on the carver however since it has no grain direction. Severe radius turns and angles are easier to do and the carving tools don't have to be kept as sharp to achieve fast, clean removal. A more creative approach can be used when carving Precision Board because of the ease of removal. Precision Board substrates save time because they can be purchased in large, thick sheets which eliminates the need for laminating and planing.

Routing

Routing and cutting HDU is the same as wood only is much easier on the router or saw motor. Deeper passes and faster feeds are all possible because of the no grain cellular makeup.
