Hi all, thank you for all the great posts that I have been reading over the past year. this is my first post and I hope that you smart people out there can help me.
I am trying to build a large 8' x 24' vaccum bag press and am new to this type of project. I have looked at some commercial ones and don't have the cash to buy so looking for a diy type.
I know how to make the bag but I need help with sizing the vacuum, how to do it, I am leaning towards a venturi pump with my large air compressor but don't understand the how it all works. To start with I found a great veneering set of plans from joe wood worker .com and am building his v2 plus system. It will work for smaller projects but not for my larger projects.
I need to have the press hold 4 psi of for a couple of hours. Could someone please point me in the direction that I need to go.
Have a great day.
