RE: Vacuum Bag that 424 Wing
Make a vacuum bag out of a piece of 4 mil plastic tarp.
The plastic is twice the length of the core and it is about 18 " wider.
The purpose is to have the bag ready for the next steps.
A piece of rope is taped along the trailing edge.
Cut a section of paper towel the length of the cores.
The purpose for the rope and the paper towel is to provide a place for the vacuum to flow.
