I'm replacing the vertical and rudder and it's not fitting.
My plane... Mid-90's slow-build RV-6. I think it's a very old serial number.
Several problems..
I had a heck of a time finding a vertical that even looked like it fit right. There are at least 4 "flavors". I finally found and stuck with the smaller counter-ballanced vertical/rudder. I think is one of the last QB RV-6 vertical/rudders built.
So I put it per the plans with the normal front spar tab and plate and bolted the rear spar to the last bulkhead.
First problem...
The rear spar bends at the fuse bulkhead only a little, but it's bent and the flanges are even buckling a little.
Second problem...
The lower cowl has to be way out as it interferes with the lower attach bolt.
Third (saved the best for last)
The counter ballance interfers and scrapes the top. It needs to be about 1/8" higher, which is a ton.
Here's what i think I need to do *please help*
1 - move the rear spar up higher
2 - Cut the front spar down so it sits lower
3 - Shim between the top of the fuse bulkhead and the rear spar till it's straight.
4 - Open up the counter balance, drill out the rivets where it joins and make a new counter balance section that's higher.
1,2 & 3 should result in a straight rear spar
I'll post pictures in a minute.
Thoughts?!
