Step 3: Clean the metal using the sandblaster

Picture of clean the metal using the sandblaster
The surface of the aluminum piece was pretty banged up, mostly from before the water jet step, but it also had some artifacts from the 60,000 psi blast of water and abrasive.  I took it over to the sandblaster for a quick clean-up.  The result was a nice uniform gray finish.
