From my research so far. It looks like earlier years were made of cast aluminium. Later they were changed to stainless. I was able to talk with Rudy. (Yes, he is still around.) He has not had a request for the new stainless stem head bow roller shown above for 8 years and he sold the last one. He gave me the name of the company that might have had the blueprint but the company no longer has it. The company that originally made them is out of business.
I went to a local marina today to see if I could find another example of the stem head that I need. Almost every sailboat new and old had a single stainless strap that connected to the forestay and roller furling drum. Even a smaller model O'day used a stainless steel strap. I wonder if any of the newer 86 to 89 34/35's used a stainless strap instead of the combination stem head plate and anchor roller? I have a call into Rudy but I have not heard back yet.
Can anyone think of why I wouldn't be able to convert mine over to a SS strap? Much larger Catalina's and Beneteau's have them. What load factors would need to be considered and what thickness of SS would be needed?
Any help on this would be very much appreciated. I'm running out of options.
