I am wrapping up the plans on my new shop. It will be 32' deep x 45' wide with 12' 2x6 walls and roof will have a 6/12 pitch. The shop is configured as 3, 15' bays. Bay 1 will have a 10W x 8T garage door, scissor trusses (on a 4/12 inside pitch) and eventually a lift. This will be the bay the Camaro gets rebuilt in. Bay 2 will be exactly like bay 1 except no lift. I will park my truck in this bay and also use it for maintenance on my vehicles. Bay 3 will be the workshop portion of the shop. It will have a walk in door and will house all the shelves, workbenches, welder, compressor and that type of stuff. Bay 3 will have the regular, triangular trusses allowing for a 12' ceiling. I want the garage door tracks to follow the 4/12 pitch, similar to this picture... This way the garage door will not interfere when a vehicle is on the lift. I stopped by a garage door company today at lunch and tried my darnedest to explain to the lady how I wanted the tracks to be installed. She kept trying to sell me a roll up door instead. Finally she told me she never heard of installing a door the way i mentioned. Then I asked for the rough out dimensions for the 10x8 doors...she tilted her head sideways with a big question on her face. I did resolve one thing, I am not buying my garage doors from this company!!!!
