Thanks for your comments. For me on my project, I am as interested in seeing what I can scrounge and save as anything. If it were all about efficiency, I wouldn't have embarked on this project at all. I get an awful lot of pleasure out of reusing something, much more than driving to the store and buying it. If I have bad experiences with what I am doing, I am not too proud to change mid stream. What I will gain is learning.
