Thanks All for the kind words. Bullwhacker007--You need to make a new years resolution NOT to break any more bones! I've been through the broken foot (and ankle) thing and it was no fun.
Unless you just want a pneumatic door, I think I'd repair the L/A you have. With air you will need a tank and a pump which just means more stuff to keep fixed. I do like the idea of a single piece door, however.
As to Photobucket, They seem to be pushing a new format. I'm trying to learn how to use it but after numerous failed attempts they ask if I want to go back to the original format and let me slide. They assure me I'll "love it" once I get it figured out
I spent New Years day playing with the air door and have nothing to show for it other than a schematic for its installation and a good understanding of how a pneumatic solenoid switch actually works
. Oh well, slow work takes time I guess.
