So I'm installing a reinforcing sleeve into a boom, and I've got a couple new questions.
Based on previous threads, I already learned to check the rules in Rule 18 for a diagram, and rule 18a, which tells me that the reinforcing sleeve is placed so that the outboard end of the reinforcing sleeve is at most 48" from the inboard end of the boom. This surprised me because it meant that the reinforcing sleeve is NOT placed right at the (inboard) end of the boom, but reinforces the area between the vang attachment point and mainsheet attachment point, while extending a bit beyond both of those.
SO, here are my questions.
1. Did I get that right about the position?
2. The reinforcing sleeve is somewhat smaller in diameter than I'd expect; it's not a snug fit by any stretch. Any suggestions on how to place it within the boom? My thought is to try and have it resting against the bottom of the boom, so that the rivets that attach the mainsheet block go through boom and reinforcing sleeve with a minimum of space, and then once it's fixed in position by those rivets, drill and rivet the vang attachment strap into place.
3. I'm pretty handy with rivets, but while I've got all the hardware off the boom, are there any fittings that folks would recommend I go immediately to a "through bolting" technique on rather than riveting? Through bolting anything that isn't right at the end of the boom, where you've got good access in order to place internal nuts, looks like quite a pain.
