VQ 31: How can I determine if my project is too wide or tall for a vacuum bag?
There are times when you may need to put a relatively large project inside a vacuum bag. Most vacuum bag suppliers offer a 54″ maximum width on their bags. You can visually determine if your project is too big for a vacuum bag by using the string theory below. You can determine if your project will fit inside a 54″ wide bag by cutting a piece of string that is 104″ long (or double the width of the vacuum bag minus 4 inches). Tie the ends of the string together so you have a string loop. Find of the area of greatest girth on the project. Drape the loop over and around the project. Now simply imagine that the string is a cross-section of the bag. Use pieces of tape to hold the string against each side of the project. Do this all the way around the project so that there are no gaps. This will help you visualize the way the bag will pull onto the project. If you can apply pieces of tape to hold the string against each part of the project, then it should fit inside a vacuum bag. If there ar
