Squeezed into footwell on modified platform. Clearance is improved, but still unable to set blind rivets in baggage door inner skin; too difficult to get both arms into work space. Wedged wood into hinge area to support hinge on fuselage side during match drilling of hinge. Took two tries; taped wood in place and got first hole drilled and cleco inserted. Progressed from there until all hinge holes were match drilled.
