In my world, the words "easy enough" generally imply something that can be done at home. Heat treatment of aluminum? I can have it done at the office, but beyond that I wouldn't have the first clue where to go around here to have that done. Certainly not my garage. In other words, I don't think the words "easy enough" apply here.
