The A-Frame design is intended to be sturdy and simple. On paper, it certainly seems to be a simple task... bolt a few pieces of lumber together, in the shape of an "A" and stand them up.
Unfortunately, the building inspector required heavy 2x10 douglas fir lumber (we had planned to use 2x6 pine) and we questioned whether we could even do this without a crane. Given the size of our "A" (24' x 24') we opted for two piece construction figuring a full 24' truss would be too heavy to stand up. Our heavily wooded hilltop site would not allow for even a scissor-lift to be brought-in.
We decided that a practice run was in order, so we pieced together a lower truss in our driveway. The trial truss went wogether easily and we stood-up our "lower A" with no problems... as you can see, we were pretty pleased.
