Thanks to everyone so far, who has provided help in the construction of our first Lehman. I have another question, and to all of you, I'm sure this will probably come off as seeming as though I am quite dense (hopefully not, though 8-), how do I determine how far from the end of the boom to place the mass (weight), and is 5 lbs. of mass about right?
