Here is a picture of a plug with gel coat on it.  What would be your recomendations for infusing this. Keep in mind once this is a mold it will be basically a U-shaped mold. The kick out you can see in the picture is not on the other side. the other side is smooth.  The lowered sections in front and back (left to right) are flange area. The part area is 32" (813mm)long. The max height is 16"(406mm) and the max width is 16"(406mm).

 I really only see two options....

1. Infuse from the side and let the resin go out along the flange in the spiral then go down one side of the U and back up the other side of the U....

2. Infuse from the end and have the resin as it enters have to climb up the walls of the U in the spiral then across the part.....

Any sugestions would be greatly appreciated. Please be specific as to where I should run the spiral.

Thanks,   Dennis

Thanks for the reply's,   Warren...The car this is going in is a full tube chassis drag car. It currently has a removable aluminium tranny tunnel. I am updating the car and making the interior C/F.

I did infuse this part on 1/2/13.....It is still in the mold so I don't know how it looks yet. Putting the layers of C/F was not that hard. when it started to be a pain was with the peel ply, But the huge pain was the infusion mesh. This stuff does not contour well at all....I ended up cutting it in sections and putting in multiple pieces. There was some places where there was no mesh and boy did the infusion slow down alot. Total infusion time was 38min. I was guessing it would take 45 min so it was better than I expected.  I did make this in one piece. I had the infusion point in the middle on one flange with spirial runing the length of the flange then down the two sides to the deepest points.  I then put two vaccum ports evenly spaced on the other side with spiral running the length on the flange. Seemed to work well. Neither side finished way before the other. I just hope this part comes out well.....Really dont want to use up another 3 yards of C/F.

I am 3 for 4 on getting bags to seal. They may not look pretty but the hold.  I had one I just could not get to hold so I had to rip the bag off and do it again. It was such a slow leak I could not find it. I think it was in the bagging material but had no idea where.
