Brief Description: Mounting VS
|
|
I finished the mounting of the vertical stabilzer today -- almost.
First, though, I fabricated the two rudder stops and put them aside for later.
Next, I checked the level of the fuselage and rechecked everything I did yesterday. I removed the VS and drilled and bolted the F-812B rear spar attach angle/control stop to the fuselage.
Then I remounted the VS and spent some quality time getting it aligned and perfect. Then it was drill, cleco, check the alignment, drill another hole, cleco, etc., then increase the hole sizes until each was big enough to insert a bolt. Everything worked out great except one hole at the lower end of the tailwheel mounting weldment, which is a bit oblong because of a bonehead error on my part. I may install a fourth AN4 bolt down there to make myself feel good about it. Otherwise everything looks spot-on, square and lined up.
The only thing left to do is to remove the VS and install the 11 rivets that connect the forward spar to the connector plate (the clecoes in photo #3).

I made the rudder stops in accordance with Van's plans. Bad idea, as I'll find out later.
