Hi guys, was browsing the net looking for some information on this and that. Came across the composites central forum and read a post regarding the EC video on perfect resin infusion and the ensuing discussion.

They question some of the methods in the video, some say to leave the pump running til gelation/cure, others dont. 



Care to take a read of the short thread and give some feedback? 

It has definitely caused me some confusion. 

Cheers

Hi Matt

I totally agree with you.

The single most important thing I have learned from you is the turning off of the vacuum pump. Thats a scarey deal if you don't have your confidence up.Who would ever think of closing off the lines in the first place! It wouldn't have occurred to me. The first time I did and got no pinholes I became a believer. (of course the resin viscosity was the other part of the puzzle I had to overcome. Heating the mold and the resin first).

Yes for compaction and strength you want the pump running, but for cosmetic parts it is a totally different story.

Thanks Again!
