Stringer glue-up!

Waiting for the epoxy to cure on the stringers. We laid 4-mil plastic under each stringer, over each epoxyed joint, and stacked the next stringer on top, added weight to keep the joints level, and turned up the heat. We used the fast hardener, the temp was an estimated 65-70 deg. F. It took about 4-hours for things to cure to the point we felt safe in flipping them over.
