May day today (which is different from 'mayday! mayday'!) Don’t know what that means, but it is a nice day today, anyway. I looked over the keel spar carefully and tried to put the tape measure down the inside of the aft tube to see if I could detect the edge of the inner sleeve. I couldn’t tell with certainty, but it seems like the tape measure hung up on something some distance down from the cut-off part. By adding up all the numbers, it would seem that if the inner sleeve runs from the place where the tape measure hung up to the end of the spar, the length of the inner sleeve would be 30” and would strengthen the tensioning area. That makes sense. In an earlier e-mail to Larry Miller, he thought the inner sleeve might be at the attach point, but that is where the outer sleeve is, so it makes more sense for the inner sleeve to be at the tensioning area and the outer sleeve at the attach point. Of course after I measure and diagram the hole positions we’ll cut up the spar and I’ll verify the sleeve configurations. This was much more complicated than I anticipated, but I think I have a handle on it. The left leading-edge spar is not as complicated; just a single tube that will simply require the holes to be positioned in the right place.
