Hi Don,
I hate to show my ignorance here, but where do you put the model to dry?
Do you put it in the plastic container on top? - This would indicate to me you are using the light bulb to create a convective flow of air for drying? - if so, do the circles I see on the plastic top act as cutouts to allow warm air in and then it exits at top of the inverted plastic container?
Sorry for the dumb question, I was thinking the parts to dry originally went in the wooden box with the bulb and that did not make as much sense to me
Thanks - I am getting ready to build something similar
Joe
