I'm building a 32x32 ft barn with a Gambrel type roof. I have the design for a gambrel rafter arrangement which uses plywood gussets on BOTH sides of the joints between rafter sections. I plan to glue the gussets, but also nail them on as per the plan (concrete nails used due to high shear strength).
Can anyone suggest a good way to set up a jig for assembling these, that has some way to nail BOTH sides of the gussets without turning a large unfinished rafter unit over the other side up??
I could maybe put the whole thing up on the side of the barn frame...
I plan to lift finished units with my small crane, up to the second floor, so "right side up" seems like a good thing...
I know the commercial units use those metal gussets that are hydraulically pressed into place...
Anyone done stuff like this? Suggestions appreciated!
