I just thought that I would take a moment to show off my handiwork:
I built this pull up bar back in October, as a birthday surprise to Scott. He's pretty darn tall, so his toes hit the ground while kipping on standard pull up bars. So, in order to help him conquer "the butterfly" (which he now has!), I decided to build this one in our garage. I looked online for examples and inspiration, and finally just decided to draw up my own "plans". Once I decided what I wanted, I headed to the plumbing and building departments at our local Lowes for some help cutting my 2x4's and pipe. A few hours later and VOILA!
