Finally back to work on the rudder. After replacing the VStab fin skins with the carbon ones, I fit the rudder again to make sure of the fitment and the width at the counter balance horn. Thankfully this seems to be good. I did take of very thin layer of foam from the side still to be covered to compensate for the .5mm thickness of the carbon when I sheet it.
Before I can get to sheeting, I trimmed the trailing edge using a straight edge and then sanded it with a 50cm long block to make sure it is straight. This was required as I want to install the trim tab into the trailing edge before I put the final sheet on. So, before I could do this, I sanded the trailing edge and then put a bit of flox on the trailing edge just where the polystyrene was trimmed away to smooth the sharp uneven edge. I did this because I put down another layer of carbon UD, just the width of the trailing edge, but I put the inside edge up onto the polystyrene, over the flox bed I prepared. After ensure a good wet out, I stalled the trim tab using flox, smoothing the edges with flox. I then finished everything with peelply and laid a straight edge over the the peelply and weighted it down with dive weights.
The rudder was put on the polystyrene cradle from which it was cut to ensure a straig trailing edge. I trust I'll get the perfect edge I'm after with a solid trim tab.
The plan is to put another 2 layers of UD over the the trailing edge and trimtab before the final carbon sheeting is done.

- Trial fitment of rudder with the new carbon skins. Also trimmed the skins trailing edge so they are equal

- Rudder on its cradle and trailing edge to be trimmed straight

- Trim tab weighted down with straight edge under the peelplay

- Straight edge on the trailing edge for curing
