Component Weights

I've personally found it difficult to find weights for certain items or the weights listed aren't even close to actual weight. Because of this i've decided to compile my own list. The parts listed have been weighed on a digital shop scale. All measurements will be in grams but are easily converted to other measurements by doing a google search.
