It is indeed quite easy to make an oven to do this kind of thing.
We made an oven for post-curing carbon-epoxy composite parts, primarily wing tips made with epoxy that requires a 150F post-cure.
The "oven" is just a box made from 2" styrofoam insulation available at home improvement stores. We pin the panels that form the box together with bamboo shish kabob skewers. Then we tape all the seams with 2" wide aluminum foil tape.
The heat source for the oven is an electric hot plate from Goodwill, and a 6" desktop circulating fan. We use a couple of oven thermometers stuck through the foam to the interior to monitor the temperature.
With the big L-39 "CEllipse" racing tips in the oven, it takes about 2--3 hours to get up to 150F, which is what we want for the post-cure cycle. Adding another hot plate would bring the temperature up faster obviously.
Becoming a repeat offender! Starting another RV-8 that will have the composite tapered wings
