I finally got the mast for #223 re-cleared and I'm now re-assembling it. Unfortunately, it's been so long since I broke it down that I don't recall how the jib halyard sheave was fastened. The self-tapper is obvious. But how should I through-bolt the loaded side? Screw head out? Screw head inside? Where should the washer(s) go? Can I assume that no backing plate is required since it's in a reinforced section of the mast? I'd appreciate any input, including any pointers regarding the methods for getting it done inside the tube. Thank you.
