I have been re-building my steering system on a 1989 Catalina 30. I just replaced the wire and I am in the process of trying to secure the take-up eyes and re-assemble the Radial Drive Wheel. I replaced the chain a few years back and honestly the boat does not get that much use, therefore I re-used the existing chain. I had to replace the wire as it was frayed and in bad shape. I had followed Alan Gomes excellent fix by bypassing the take-up eyes and securing the wire cable directly to the top of the Radial Drive Wheel. I have not been happy with the steering tension for the past two seasons and finally decided it was time to go back to the original design. It is a poor design which causes the rudder post to get cut as the take-up eyes dig into the tube. I may be selling the boat within the year and do not think the steering system would pass a marine survey if left as it was.

I have now spent two afternoons attempting to re-connect the Drive Wheel. Either there is not enough slack to put the pieces back together, or there is too much. I have connected and re-connected the cable so often I lost count. I have contacted Edson, and they have been great, but their advice is generic and does not pertain to the specifics of the Cat 30. The boat is on the hard and the shimmed the rudder so I could remove the Drive Wheel and not have to worry about rudder moving. Actually, since I am a Wing I cannot drop the rudder anyway.

Does anybody recall doing this project and have any advice? I need to keep enough tension to allow the take-up eyes to do their thing. Otherwise my steering will be too loose and the wire will jump the Drive Wheel. It seems the two clamps have to sit so far back, they do not have enough room to allow me to reassemble the Drive Wheel. If I move them up, then it is too loose and I start over again. The only thing I have not tried is assembling everything with the wire off of the Drive Wheel and then attempting to reassemble the entire system. I am going to attempt one more time and then hand it over to the Yard. Something I have been trying to avoid. Also, any suggestions on how to cut off the extra cable. I must have 3 feet left over. I noticed the cable supplied by Edson was cut with a torch since the ends are fused. I am concerned about the cable fraying. I was going to simply wrap it with electrical tape and cut it with a borrowed Cable Cutter. That is unless someone has a better idea.
Many thanks.

use a right angle grinder and cut off wheel. still wrap the cable with tape though. you shoujld get a faily clean cut if you let the wheel do the cutting. I don't have a Cat but the cable ends on my edson steering have u bolts clamping them and the eyebolts are long enough to actually over tighten the cable.

Catalina MKII Vancouver
Just went through this exact procedure, and it was a nightmare. It took two of us, all day to install the new radial wheel and cables. We had the system together and apart many, many times before we finally got it right. Many explicative words were uttered throughout the process. I believe the main problem here is that Edson intended the radial wheel to be used where there would be bottom side access for assembly. This is not the case with the C30 MKII where the radial wheel is located in a shallow pan in the deck. There is no bottom side access so a lot of it is done by feel. Getting the cable length just right is pure misery, as well as positioning the clamps, and this is where all the time goes. The clamps and tension eyelets will want to rub against the tapered fiberglass post, not what Edson intended, I'm sure. It takes a heck of a lot of fiddling to get things positioned as best you can, with the clamps positioned such that the protruding screw ends face away from the rudder post, or they'll gouge into it badly. As horrible as the job was, in my case, I would not have let the yard do it. I suspect they would not have been nearly as careful in getting everything positioned just right. I don't blame Edson for the misery, it's just the way Catalina employed the drive wheel in the MKII, IMO.
