Rob, here's a picture of the bow as it sits in the press. Excuse the messy bench, but it's all I have for now until I build my own place.
Finch, I ran into the same issue you did once I removed the cables/cams. I relaxed the press, but it wouldn't relax enough to get the bow out. I know I probably shouldn't have done this, but I just pulled out slightly on the bow evenly, and it popped out. That's one thing I'm not happy about with the press.
Anyways, I backed off the limb bolts (as per RJs suggestion) so I would gain a bit of flex there, and I even have the top portion of the jack adjust upward like you mention Finch, but I'm still about 2-3" short.
Rob, there is some adjustment with the links at the end of the cable where they hook onto the one arm, but you can only get up so many links until you can't hook it around the j-hook anymore. I have everything as snug, adjusted, and maxed out that I think I can get it.
