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!

Haha yeh I concur. The PID is the most expensive bit, the rest of my oven including element and fan/motor was only around AUD$100-150.
