Re: HEX broach too big for our manual press
Check out this thread (http://www.chiefdelphi.com/forums/showthread.php?t=140878) for some ratcheting presses that are large enough for a 1/2 hex broach. I have a post on there on how we got the...

I feel like there was not enough of an incentive to be a tall bot or to do all 5 defenses. Not exactly sure how to fix that.
