Foam latex oven

A couple weeks ago, we needed to cook foam latex in a three part mold that would make a skirt. The two halfs and a core piece, three part mold. Should've known that an old oven bought online would bring disaster. It did and it destroyed the core piece of the mold. Sucked, sucked alot. Repoured the third piece again in 1630 and cast the foam latex again in a convection oven. Not our oven but an oven built by the great Rob Ronning.(He also built a walk in oven where Oogie Boogie was cooked). So, after three more failed attempts at cooking the foam latex, Rob gave us some advice and we followed through. Turned out to be a success the fourth try. But having to use someone else's oven wasn't ideal with all the traveling back and forth and not being able to check the mold didn't sit well with us.

So I decided to just make an oven. My boss liked the idea that she greenlit the oven project. It took two days to build the oven. On the first day it was straight forward cutting and screwing. The second day, was the more subtle work and the most patience. The amount of cuts I received from aluminum tape sucks and still feel today. And yet, somehow without ever attempting to make such a thing, it appeared like the schematics i drew and like the way the pros have it. Add a few more points to my ego please.

My only regret is not using better material. I had to use polystyrene, which works fine and perfect, but there are better materials. had to use cdx plywood which is a lot rougher. Had to use small wheels, which are fine but there are bigger ones with the step brakes. What really matters in a convection oven is the insulation the heat source and the fan, those weren't generic. Can't be.

I think I did well, my boss couldn't stop opening the door and looking at it. We're dying to use it. It can keep a constant temperature and won't burn. But we want so badly to have our first foam latex done. Here are some pics:
