27th September 2011 - Tapes

The next few days are going to be spent applying finishing tapes to the fuselage and vertical and horizontal stabilisers. I'm following to Stewart manual and videos precisely. Rib tapes are stuck at one end and the glue allowed to dry to a reasonably strong bond. Then the glue is applied along the rib until just before the other end. All excess glue is wiped off with a paper towel. The tape is pulled tight to cause it to conform to the shape of the covering and the glue again allowed to dry. Finally, the tapes are cut to length and the end glued. The joints between the fuselage sides and top and bottom will be reinforced with 3" finishing tape. In this case the tape is folded in half to get a centre line. The centre of the longeron is painted with a glue line which is allowed to get tacky. Then the tape can be positioned accurately over the longeron centre. The glueline is ironed to thermal soften the glue and bond the centre of the tape in place. Next the tape ironed flat against the top and side. Finally the edges of the tape are lifted and glue appled about a foot at a time with the excess wiped off. So far I've got the tapes completed for the vertical stabiliser, the top fuselage side joints, the right fuselage side stringers, and the horizontal stabiliser ribs. I've also applied the reinforcing tapes along the top stringers ready for the fabric attach rivets.
