Sounds quick and easy and if you are really Starting out making nails you will need 3 or 4 heats and should not feel bad about more until you get the speed and rhythm down.
There are several variations on this basic method and we will discuss what I will call the "Peter Ross", "Jerry Darnell" and "Tom Clark" approaches later in this article.

Indoor storage should be in areas having floors pitched toward a trapped drain or in curbed retention areas. Use surface active agent (eg detergent, soaps, alcohols), if approved by USEPA.
