I'm curious what is considered the best blasting media for aircraft parts ?
Plastic? Soda? Walnut shells? etc ? What media do you use and pressure ?
The short answer is "yes"
Soda and walnut are great for removing paint, but won't remove corrosion from aluminum. Walnut has the advantage of being soft, and soda is water soluble so rinsing it way is easy.
Glass bead will remove corrosion and yield a clean surface, but will erode aluminum surfaces without care. (DO NOT write your name, or anything rude with a bead blaster on a panel - it WILL telegraph through the paint. DO NOT ask me how I know this) and stray glass bead in oil passages is a BAD THING.
Pressures will vary according to your machine,the object to be cleaned and operator skill. Easily adjustable pressure is a must, but with low pressure and care it's possible to bead blast steel parts without removing ink stamped part numbers
As noted, clean the grease oil and dirt off as best you can before putting it in a blast cabinet.
