When I picked up the squeezer yoke from local builder Kent Stitt he mentioned he had used the yoke as a bucking bar in some tight spaces. We gave that a try and it worked like a champ. Finished the flush rivets and then completed the rib to spar rivets. Jason's friend Andy visited the shop and we used the extra hand to secure the stab while we drove the last few rivets. Vertical stab finally done!
