Re: Cutting Keyway in Rudder Shaft for AP
If you presently have an existing steering
quadrant, and not a tiller arm as you originally stated, fill and thru bolt the wedge shaped opening in the quad with hardwood fillers and aluminum
top and bottom plates to hold the ball joint.
Have fitted a number of A/Ps like this.
I was referring to the AP tiller arm, sorry for the confusion. I also installed an ap on another boat
on the quadrant because the owner really wanted it that way. I personally like the shaft idea because if one of the quadrant cables
ever breaks(I got spares and check the existing ones), I can use the AP to steer the boat
Yes, the emergency
tiller fits on top of the shaft and there is still about 2 1/2" of room but I think it will not be enough. If one cable breaks, then the AP also breaks down, I can unbolt the tiller arm and then fit the emergency tiller there.
Sounds like a harsh day
