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 replies.... I definetly do not want a split line in the part if I can help it. Especially since where it would need to be is the most visible point of the tunnel. I will do as Matt sugested which is more or less what I was thinking.

IF for some reason it doesn't work my plan is to infuse past half way from each side them do a few inch strip on the top then bond the strip to one half trim everything and use Dzus fasteners to put the two halfs together.

Getting closer to doing my first infusion and I am both excited and nervous at the same time.  I was a neverous reck the other day after I made my first molds wondering if any of the plugs were going to to release and if the surface would look ok. Everything so far is good.

Thanks, Dennis
