    Begin with a component you can afford to throw away.

    There is a lot of members here who are masters in infusion. Hope they notice.

    Use 1/2" [12mm] ID tubing for everything
    Buy an ultrasonic leak detector.
    Buy a handheld heat sealer and use it to make your bag pleats.
    A digital vacuum gauge placed between the vacuum on/off valve and catchpot is useful for doing a drop test to determine if you have any leaks.

    Does the heat sealer work for regular wet bag work? I hate pleating.

    Can perforated core be infused? I'd like to try some infusion, but mostly just on stuff I can risk.

    What media would you recommend for flat material no kerfs?

    As long as the heat sealer is the proper heat rating for the bag, yes.

    Cores should be grooved and perforated.

    I don't use media. I let the material control the flow rates. As long as I keep 30 inches between the resin feed and vacuum zone always, it works out fine.

    My resin and vacuum lines are pre-made by my fiberglass company.

    Resin feed ; spiral cut hose, with a tiny amount of peel ply around it.
    Vacuum ; spiral cut hose with a 6" tail of peel ply. I was taught to pull the hose / tail end up in to the infusion bag, rather than leaving it on the part. This reduces resin waste.

    You don't want to use a ton of peel ply either, that stuff flows like crap.
