Thanks, 



Hi Wesley, sounds like you have worked out the problem.
If cosmetics are the priority once the resin reaches the vac outlet and all the cloth is wetted out I clamp off the vac line. On a sheet that size I would leave the feed line open for another 30-40 seconds to ensure the part is resin rich before clamping off. A good guide is the resin feed connector, leave the feed line open until the connector just starts to feel loose under the bag. One slight downside to this is that your silicone connectors wont last as long (5 or 6 parts), you will have to dig them out of the resin. Not expensive and certainly cheaper than a scrap cf part.
 
If strength/weight are the main factors then as soon as the resin reaches the vac outlet clamp off the feed line followed almost immediately by the vac line.
If the bag has a perfect seal and the resin has traveled through the part at an even rate then resin shouldn't even reach the catch pot. Just a few inches up the hose. People tend to see the bubbles in the hose and think that there is still lots of air in there and leave the vac line open. The bubbles are actually tiny amounts of air expanding under vacuum making them appear much bigger than they are. I have seen people fill the catch pot with resin waiting for those bubbles to disappear, they wont.
Hope that makes sense and helps a little.

Warren
