Hi all,

About to cut out and bend the ribs for my Bearhawk wings in the next week or so, and I know I'll have to, at some point shortly afterward, cut out the rib stiffeners and attach angles (90-degree strips riveted to the side of each rib). Just perusing one of my fellow builders' logs, and he had 370 of those little monsters made up at the time he created them. Since my building partner and I are building two of these aircraft, that'll make 740 of them, and wondered if a tool like this one would pay for itself in time saved for such an event:

Of course, it'll be handy for plenty of other metal operations on the plane as well, and maybe its big brother, too:

Any opinions on these devices?
