I started having a bit of trouble doing the inside ribs and the leading edge rivets, so I bought a couple of portable work horses and found this a lot easier to work around instead of on the bench. So far I have 4 ribs done and 3 to go. Once you get into the groove it works out fine, definately getting easier the more I do. It takes between 1 to 1.5 hours per rib but this time includes all the set up and clean up.
