  1. I appreciate your problem - we've all been through this at one time or another! There are a number of ways to deal with this. Ideally there is a small amount of stretch in the shrouds that will allow for micro-adjustment. However, don't overdo it or either the lanyard will give way or the mast will pull out of line.

     

    For the main part of the process I will loop the end of the shroud up (once it is in place over the masthead) until the bottom of the loop is at the level you want the deadeye to be. (A bit of water on a brush applied to the shroud at the bend will help it behave.) I then secure the deadeye in this loop with a spot of glue. Take the shroud off again and complete the lashings around the deadeye on the bench rather than in the air. Then re-install the shroud pair and reeve the laniard.

     

    Other folk will doubtless provide you with other remedies. One size doesn't fit all - try them until you find one that works for you.

  2. I've used many different methods over the years. I began with black tissue, graduated to Allan's paint/PVA mix, and now use dark brown acrylic paint (burnt umber) along the outer (show) edges of joints on one side before gluing up. I find black a little too visually contrasty, but that's a personal preference. For minor seams such as planking, soft pencil along the show edge does the trick for me.

     

    Try different methods until you settle on the one(s) that you like.

  3. I quote a retired civil engineer (I hope she won't mind) who designed bridges world wide:

     

    I saw the newsreel of the bridge collapse in Baltimore yesterday. I had always felt that these American 'girder bridges' were too lightweight (part of America's planned obsolesce design practice in place in those years). But I was astonished to see how little protection was provided to the main supports. It's a no brainer - if you knock out a main support, the bridge collapses! And the main supports next to the navigation channel require special attention. On the Queensferry Bridge, which was downstream of the Forsyth Naval Dockyard where they build and maintain aircraft carriers, we carried out a study, including model simulation, of just such an event and designed the main pier caissons not to fail. Luckily, the Americans loved simple span construction for their approach viaducts and this acted as a fuse . . . [for] progressive collapse of the whole crossing! . . . .  what happened using 'the past is a foreign country' adage. It was opened in 1977! I was working on the Itchen Bridge then in a similar, but not as exposed, location upriver from the port of Southampton. Our River piers were protected by a massive caisson that extended out from the main columns by sufficient distance to guard against the superstructure hitting the bridge even as the hull of the vessel crumpled onto the caissons.

     

    So, there you have it.
