I use Tinker's way but with this caveat. I always want to have enough scrap to cover any error's and also enough to build a smaller project in the future should I desire. I don't like the pressure of worrying if I'm going to make it with what i got. And, if you've shopped right, it won't likely be any cheaper or convienant to get than it is at this moment.

Best rule of thumb I have is... BUY MORE THEN YOU THINK YOU NEED. I always purchase more then I plan on using. I always buy in mill lengths as it's cheaper. If I purchase off a list of required materials I always add a piece of each item in case I have a senior moment (cheaper then delivery charges). No matter what you'll use what you've order one way or the other I know I always do.
I built $4,000 dollars worth of commercial film racks for my employer for $2,000. I ordered double scrap, 300 amp arc welder and a O/A welding setup. I used the double scrap to make a jig to build their heavy duty shelves! I broke even but now had a garage full of scrape and welding gear They saved 1/2 of their money. Took one weekend for a rookie to accomplish it.

Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.
It is true, there is nothing free about freedom, don't be so quick to give it away.
