I did a quick search on this but couldn't find an answer so here is a new topic! Can a household oven be used for curing? Other than a vacuum bag port of some sort, what modifications absolutely need to be made for it to work? I have access to a cheap used one that i could put in my garage but wont bother if it wont work well for composites!

If yours is a gas oven rather than electric, then I wouldn't want to suggest an ideal controller as gas ovens are not a familiar area of expertise and the potential to blow up your house is quite high if the gas burner is modified and not properly checked.   The PID controllers generally are switching, via a relay, an electric element which in most cases has a fan to ensure even heat distribution in the oven.  I would imagine a gas oven would not be that evenly heated.
