Hi, again, Branwen. The ice scraper is the "big, manly way" to remove the flooring but it is hard on the back and the arms and the hands. But then we tend to be better at "strong back, weak mind" things. LOL And you don't stand the chance of tearing up the floor so you have more problems sanding. You came up with a good approach.
We are happy to help at any time. Your father has gotten smarter as you have gotten older, hasn't he. And he sure is right.
