RJM,
cool!!! [8D]

I'll tell you what, if you have a steel door you may want to consider going to magnetic building system. Great Planes sells one for $130, but it's an overpriced plastic piece of junk. I built mine from scratch. RCU member Cafeenman has the instructions on his website, but unfortunately I haven't seen him on here since Katrina hit and I'm afraid he got hammered in that storm. But trust me, it's well worth the effort of putting one together. One of the biggest expenses is the steel for the building board, but since you already have that you're more than halfway there.

If you're interested let me know and I'll see what I can do to get you instructions.
