Thanks for the post.
Now I won't have to look for a local plywood source. I live just up the road in B'ville. I'm still in the planning stages of my build. I'm leaning toward a 5'x10' Comet type tear.
I work construction, so I'm going to hit up the "tin knockers" on the job for a source for aluminum.
I got the bug bad. Can't go into Lowes, TSC, HD, HF or the local hardware store without looking for ideas for my tear.
I have a very understanding wife.
