A few days ago, I realized that I screwed up where I cut the pockets for the drift pins. When I measured the distance to cut the pockets from the leading edge of the rudder, I didn't take into account the width of the shaft so as a result, all but one of the pins extend into the pockets only about 1/2 inch. Technically enough, but I wanted the washers and nuts to sit on a nice flat piece of wood so I planned to glass in some hardwood pieces and the 1/2 inch just wasn't enough room.
I was planning originally to use some leftover sapelle holesaw cut outs from my grabrail project, but because the drift pins only extended about a half inch into the pocket, there wasn't enough room except for 1 of the holes (I don't know how I cut that one correctly and all the others were off). So I basically made a dutchman patch at the bottom of each pocket and epoxied sapelle blocks in for the plywood I cut out. All in all it achieved what I had intended, but it took more time than I had originally planned and I'm still kicking myself for not paying more attention to my measurements.
I left the rudder for a few days to let the epoxy cure and then bolted on the lower shaft and took everything (including the upper shaft) back over to the boat yesterday afternoon for a finally sanity check fitting before starting to glass the rudder up. Assembling this in place is a bit of a trick and is probably best done with 3 people, but I just had my wife to help me. The process goes like this:
- Insert stainless shaft up and into boat. This is where a third person would be good to have to just hold it in place while the other steps are done.
- Take rudder and lower shaft and insert into bronze shoe pin at base of keel.
- Wiggle rudder in between welded straps on top of shaft.
- Insert upper drift bolt and tighten nut.
Next up, I'll be applying a coat of CPES to the entire rudder before I do the actual glassing. It may be overkill, but I've heard it makes a good substrate for epoxy to adhere to and ultimately, there is no way I'll keep the water out forever, so this should provide a last line of defense against water intrusion.
