are you using plywood? it kind of looks like indoor paneling your using to redo the bottom of the fuse, If so... and this is just me talking.. you might want to try and get some actual plywood from the hobby shop.. I'm not sure if that stuff looks sturdy enough... but hey.. whatever works... and nice workstation... not sure about the leading edge of your wing though.. that'll be a tough one.. or atleast it would be for me LOL... because of all the stress on the wing at that point... anyway.. good luck on your repairs...
