I'm new in the vacuum infusion so I have a few questions.
I want to make a composite part and for the female mold I'm gonna use a fire scale diam. 80 cm. depth 14 cm. I had the idea to make a box around in formica so I have a flange to attach the vacuum bag. Can you give me some advice about the position for installing the vacuum and infusion line. Do I place the infusion connector (with or without spiral tube) in the middle of the part or on the flange? For the vacuum line, is a connector enough or better in combination with a spiral tube?

I would probably feed from the centre on this part and use spiral tubing around the complete diameter of the mould as your vacuum manifold (with a good 2" resin break). This will be the fastest way to infuse, and give you the best chance of getting a 100% pinhole free surface.
The catch is that if your layup is going to be very thin (ie, under 1.5mm thick), then you will get print through of the resin inlet onto the surface of the part.
