Shame on me for not bookmarking Rick's chart of where he uses what glue, a link would be appreciated. But my question is how do you apply PU glue? The stuff can be an incredible mess. The other question is what considerations change if a vacuum press is being used? I have vacuum pressed most of the current uke I am on.
I have been spreading the PU with a spatula, but still have used too much a few times, I am thinking like a toothed grout spatula could be helpful. I vacuum pressed the laminated sides and the glue did not squeeze out, but stays in making my sides have a slight curve.
I remember that Rick uses PU for headstock veneers as there is no reason to add moisture to that area and the foam out is easy to clean. How would doing this in a vacuum press where moisture is sucked out affect that issue?
Is there a re-acclimation time or a don't vacuum this part issue as a result of the moisture getting pulled out? My first tries with breather mesh only on one side made the wood really cup when joining the plates. I since have been using the breather stuff on both sides. Or is it useful to throw some plates in the vacuum to lower moisture before installing, I have heard of baking plates, wouldn't this be similar?
Thanks Rick for the great list.
