31st August 2009 - Ribs and rework

It's been slow progress over the last few days but there are now 7 ribs completely finished and one with glue setting before the gussets are installed on the second side. I've also made a jig for the two root ribs and the first root rib has been constructed, glued, and is setting in it. For the root rib jig I've just pinned blocks of wood to locate the rib structure to a piece of polythene over the full size plan as there only two ribs to make so the jig does not need to be too durable.
I was intending to have a first go at covering starting with the rudder which is the smallest and simplest structure but when working out how to fix the fabric I realised that it was going to be difficult to get a good seal round the rudder horn. In order to give somewhere to glue I welded a small plate either side of the front rudder spar round the horn similar to those installed previously around the hinges. Then this needed the priming touching up where it had been sanded or burnt off so it's another seven days for the paint to completely harden before this is ready to cover.
