Great job guys, I think you need to get a bigger vice, lol.

Ha ha. I wanted to do it without staking it into the ground but pulling on the string made it tip a lot so we ended up jamming some rebar down at an angle into the dirt to hold it all *somewhat* still :P. I think at this point we are a little more concerned with getting the body ready so we can actually get something off the ground!
