Dean in WA has got a great set up that is well worth checking out. He's a perpetual innovator!
I love the rocker table idea. He basically took a plaster mould of an existing board and tada!!! Instant rocker table which can be placed completely inside a sturdy vacuum bag - no clamping, no jigs. Brilliant!!!! He' used 1mm vinyl for the vac bag.
I've been thinking that it would be a lot easier with my set up to lay the board up with the acrylic part of the rocker table surface flat. Put the whole thing in a vac bag rather than fuck around with tacky tape and then clamp it down. I'm thinking that the vinyl would be strong enough to take the pressure of the jigs clamping down on it. Provided that there was plenty of bleeder material to soak up the excess resin then the bag would be reusable.
In the video by Fibre and Foam ( search youtube for it) her used vinyl for the vac bag too and it worked fine. However, he put the vinyl directly onto the board surface without breather/bleeder material and it left a ripple effect on the surface of the board because without the breather material, once it comes in contact with the resin, the resin is sticky enough that its nearly impossible to apply enough force to stretch the surface tight.
