Neat way of jointing and a clever jig. The few times I have done veneered projects I have done the classic cloamping between boards and pass over the jointer. This looks way simpler.
And great idea to use a water bed for the vacuum bag. The real bags are not easy to get where I live, might give this a try.
Would love to learn mode about your pump!
