Hello my friends . I am happy to be a member of this forum for advanced composites .
In my spare time i make freedive blades from carbon fiber. After using many methods like closing first the vacuum line then after 30 seconds the feed line or the opposite first closing the feed line then the vacuum line to regain the lost vacuum , still i have pinholes / dry spots . In the link below you can see all the process in fast forward .You have to download it to see and the 30 minutes.

The result of this process also had pinholes . I think that my fault here was that i closed the feed line quite early before the resin reached the vacuum hose so it sucked the resin and made it poor.
Yesterday i made a new attempt with the same process with the difference that i didn't use the adhesive spray and also i waited the resin to reach the vacuum hose and then i closed the vacuum line, counted to 30 seconds and then i closed the feed line.Unluckily the same results. I will take a photo tomorrow to see what i mean.
Today i made one more try witht hte diference that i waited 1 minute before i close the feed line to make it a bit resin richer ! Tomorrow i will see the results.
