Post needs to be shaped and hinges drilled out and set.
Wasnt sure I could accurately cut the elongated ‘V’ into the top of the post and the trailing edge of each rudder rib so got a local company to assist. They marked and cut with a grinderandmade a great job.
Hinges are pcked with temporay washers to get the hinge sitting in the middle of the bracket.
Rudder horn is cut from plate, drilled to take alloy turned collar and then pushed onto bottom of rudder post. This proved quite tight and so had to be chamfered down to take. Rembering to leave rudder leading edge hole rivet free to act a hinge point.
Before mounting, drll 13mm hole through bottom of rudder post to take trailing edge, then temporary first fit to see it it looks right !
Paul advised that the trailing edge is overized to allow builde to cut down so that the ribs fit tightly
