Hi Nick,

I just tapped the holes in the beam and used countersunk bolts. No need for nuts, plenty of Duralac in tapped holes and check them for tension occasionaly. I think some Mossies are done this way also <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />. Some Mossies seem to work OK with rivets, with low profile tracks, again plenty of Duralac (dissimilar metals jointing compound).
