Judy,
Why do you say that rivets or tapped machine screws are OK to attach the
bail to the mast, but a thru bolt is necessary on the boom? I would think
that the stresses would be about the same on each. Do you recommend not
using a thru bolt on the mast? If so, why? Do you think it might weaken
the mast? I've got the "heavy" mast and was planning to use a thru bolt
on it to mount the bail for my new vang.
