Crack machine for crack strength?

[scienceguy288]

Has anyone played around with utilizing a crack machine to train for crack strength?  If so, how would that figure into the Rock Prodigy program?  I suspect it would be integrated into the strength phase and I don't think it would completely replace a hangboard, but I don't want to wind up overtraining.

I would actually see it fitting into skill development and PE. I would still use the HB for strength. Since thin cracks tend to need lots of finger strength the HB would still work to safely train those joint angles used. Tell me what you think if you build one of these. I would like to add one to CTC
