I didn't see the original post, but want to mention the caution to
keep the air pressure low (like 30 lbs, I think) when using it to blow
chips. High pressure is a good way to blow chips into your eyes.

Wouldn't it be prudent to use some type of flexible tubing and aim it to
blow away from the users eyes? If anything, eye protection should be worn
anyway. I've seen little chips from drilling (wood or metal) shoot out at an
alarming speed.
