@jerzone there are power tools that do this and fit into tight spaces, but i opted for the $140 manual tool vs. the $399 dewalt tool that would work with all my batteries. maybe if i am building a cabin someday, that will be worth it. but for this purpose - i was able to make all the joints and make the assembly in my shop, i only had one joint to make on a ladder/in a tight-ish space.
