Another thing on safety.
If you smoke PLEASE wear a dust mask, I have several and the best I find for dust protection is the "dust be gone" it is made in USA and while it is not cheap it is the best around, it is light wont fog glasses and is washable, it comes in 3 sizes, also your hearing is important if you have noisy machinary.
Think about a few dollars is cheaper than the doctors bills
