Tell us about yourself!
I'm a physician who is residency trained and board-certified in occupational and environmental medicine. I've dealt with PPE (personal protective equipment) issues for many years.When using a mask to filter out dust particles, you don't get a very good fit if you have a beard under the mask. The air simply goes around the mask where it doesn't fit properly. This becomes an issue because you can become sensitized (allergic) to certain types of wood dust over time. You can also become sensitized to the epoxy used in plywood. Also, I throw on a pair of earmuffs when operating table saws and other loud equipment. I do appreciate you wearing eye protection in the photographs. This is a great project and I'm going to try it myself. Thank you.
I just wrote a similar post. You are correct.
