Hey everyone im looking for some advice on converting some old hand layup molds to infusion. These were some of my first molds and ive added a flange to one and tried to infuse but there are some pinholes and airleaks that i was unable to shutdown. Ive laid more glass over the back. Really tried to lay it on thick and ive tried even gelcoating over it. Im wondering if its not a lateral leak in the mold and this is why im not able to close it down. I can see where air is entering when making a part but applying anything on the back of the area doesnt cure the problem.
A friend suggested to put some glass on the back and put the whole mold in a bag and infuse using mti hose.
Short of remaking the mold which is problematic if i cant make a leakproof part to infuse a new mold from is there any way to fix what i have? Im probably making it harder than it needs to be but ive tried a decent number of things to make this one mold infusion capable and so far im not having any joy.
And i still have a bunch more molds id like to upgrade.
