I think I have a decent picture and idea of what you are describing. I have built a variety of things before so I am sure I can get something decent built. I will have to look into those materials and see what is locally available.
I surveyed the damage last night....luckily my two orchids with spikes seems unharmed. The one has five spikes and the other just has one, but it is one that I want identified so I can't wait to be able to take a pictures and post them for ID.
It was very late when I got home after 11, so I didn't get everything done that needs to be. It seems that only one pot was broken and only one seedling lost. I am hopeful that the seedling will re-surface. I do have several others though. All in all I think I am pretty lucky damage was not worse.
