Main Message Board / Rudder Play Fix options
November 21, 2021, 06:51:00 PM
I have walk thru 1.5 with rudder play – bottom of the rudder moves about ¼ inch and I can feel it while sailing. "Play" appears to be in the bottom tube
I'm aware of 2 possible fixes – epoxy and mylar film
I almost decided to go with epoxy but My quadrant has at least 4 thru bolts "corrosion welded" to aluminum quadrant and did not budge when encouraged with 12 inch driver. (I applied some pb blaster but I did not have time for longer soak)
I'm going to give it another try next weekend possibly with some heat applied and an impact wrench possibly beaker bar. I would applicate feedback from anyone with experience in this area.
My big concern is snapping these bolts and opening whole fresh can of worms.

Above makes me reconsider mylar shim approach.
Catalina instructions do not mention how to insert mylar strips into the rudder tube past the stuffing box packing?
Should I attempt to shim it from the bottom instead?
2 inch strips or wider?
What is the longevity of this approach?
Again any tips and suggestions from successful shimming operations are welcome.

I'm in the middle of electrical upgrade and found interesting product from BlueSea:  Automatic Charging Relay ML-ACR 7620 and 7622.
Is there any reason why either one should not be used as an "emergency combine" switch and ACR in one ?

One of the friction stays on my trapezoid hatch broke off yesterday. Carnage reviled 2 snapped rivets...

Quick internet searches makes me think it is not uncommon problem.

I have seen following recommendations:   (does anyone have experience with this problem or any comments ?)

Options :
Blind rivets
Solid rivets
Other fastener ?

Material :
Aluminum
Monel
SS

Anti-corrosion compound:
Duralac 

Rivet size
Looks like 5 mm diameter,  not sure about original length ...
