I several follow on questions about homemade oven/bulbs/heat and baking time. My homemade oven is 24L x 12W x 20H' lined with 3/4 inch foil backed styrene insulation and using two 75 W bulbs. From cold start to 10 minutes heat is 155 degrees; 10 to 20 minutes heat rises to 225 degrees; 20 to 30 minutes gets to 240 and then 30 to 40 minutes to 250 degrees. I allow oven 10 minutes preheat time ( about 10 minutes). I spray a piece and hang in the oven. I spray additional pieces and hang as well. I bake everything for 40 minutes; unplug oven and allow pieces to cool. Enamel paint (using Hennings train enamel) is baked hard, BUT lacks the luster of the other pieces I see on this thread. Am I baking to long? To hot?
