I'm new to these discussions and also to the topic of low-vac. Since I may soon be diving into my own Cozy project, I'm also interested the answer to JLKnolla's question. The discussion in this thread is educational for me and the various bits of embedded discussions are also valuable However, since I haven't seen an affirmative response to JLKnolla's question, is it accurate to conclude that there is no known hard data reflecting weight comparisons between parts completed using low-vac techniques against those without?
Since I also understand that there are other benefits of low-vac, I'm also curious whether there's objective data regarding strength improvements, time-savings, etc.
I understand that the technique may be somewhat controversial, but objective comparison data of the various attributes would help me make a determination about the techniques that I may use in my own construction.
