Re: Rudder Post/bar typo

I wouldn't think it would be a problem, if you are comfortable welding the bushing that thin. You would be at about .030".

Re: Ford GAV

On Ken Perkins Piet the GAV is safety wired in one position. We've never had a problem with having to adjust it. Ken just messed with it until he was satisfied with the idle and the pick up coming off idle. It can be slightly rich on a hot day, until you come off idle. If you think about that, it's ...

Re: Rudder Post/bar typo

John. After you weld or braze the bushing into the rudder bar you ream the bushing to accept a 5/16" bolt. You will want a snug fit, no slop. Ream to .313" - .3135". I'm assuming you are using an AN bolt to mount the rudder bar. If you weld the bushing it may be very hard after it cools down and be ...

Matt.

I have Ken Perkins Piet, N34KP, at the Gardner airport on 175th. street. Not the old naval air station (New Century), but the little strip west of town.

The Piet is currently under repair in the tail area, but you are welcome to come see it anytime. Bring your camera.
