yes, I suppose I could have mounted the light board after insulation, but I had a slight concern re protecting the wood from the light bulb heat. A bow will be in there for as much as six hours. Probably not a problem, but the thought occurred.
Depending on the height of your ceiling, low casters would be even better than my skids. I'm looking for a set that's low enough for me to get away with.
Final comment, if I were doing it again, I'd look really hard at that all foam constructed one like Areonaut's. Maybe not as durable, but probably plenty strong enough with reasonable care, and would be much easier to handle.
