SO inquiring minds want to know....Are these Magic clamps? Is the secret in the Orange color?

huh?

And then, of course, there is the REALLY high-tech method involving clamps - but it's too complex to describe here - besides, it's proprietary..... :

Dale, Dale, Dale - VACUUM!!!!!!   WOW, that is quite an impressive array of hoses, but a very simple vacuum-bag system works at least as well - perfectly even pressure over the entire surface. I use a little pump that maybe cost me $200 or so and I had a bag made for me about five-feet by two-feet or so for all my rib laminating and pinblock capping. It is low-cost and works great. I'm sure your air-hose thing works well, but for others considering doing something of this nature, IMHO, vacuum bagging is much easier and low cost.
