Buy American !!

Several years ago I was interested in a wood stove from U.S. Stoves supposedly the oldest stove company in America when I checked label it was made in China. My wife would not let me by it. By the way that tool you made would be good for removing foam in the outer skin in an electric drill you would have a 1- 2 in dia hole depending on the length of the right angle bend with the skin still intact(except for the hole to insert the bent drill). This hole can be filled with a potting compound like Epocast where you need extra strength for attached stuff to the out side of the MH or where awning bolts have pulled out for example.
