      Hi Nels, Yes,the chines were slightly beefed up to take the
      fastenings without fear of having the prescribed 3/4" square chines
      split. As for the"steaming" of them,it was just a couple of
      towels,wrapped around the chine at the point of greatest bend,soaked
      with hot water,covered in plastic and left over-night with a weight
      attached to the outboard end.When I returned the following day,the
      chines had settled down to their new shape:-)

      The primary reason for my use of screws has to do with how I like to
      build.That is,I am a firm believer in the "dry fit" whereby whatever
      you are assembling all gets put together without epoxy and tested for
      fit.Once the piece is"perfect",it is unscrewed,epoxy is then laid on
      and the whole thing goes back together precisely since you can now
      use your screw holes as guides.Another benefit is that a screw will
      let you draw a work together gently without all the noise,hammer head
      dents in the wood from missed strikes and general violence usually
      associated with a swinging hammer.Ring nails are just as strong as
      screws but do not afford the above advantages.
      I suppose that one could remove all the fastenings and trust the
      epoxy to do its job.At the time when I built LESTAT,my faith was
      still somewhat shaky.

      I recall it as more a 1X6 but what's a couple of inches between
      friends :-) but yes,that is how it was done with the keelson only
      running between the two ends of the enclosed living space and not out
      to the transom nor the stem(bow transom). I wanted it for the
      spreading of the loads expected from the traditionally hung ballast
      and to prevent the bottom plywood from flexing the wrong way and
      developing a convex bottom.

      For most of the boat,I used s/s Robertson drive number 8 screws with
      some number 6 and 10 where thought best and a few number 14(yikes!)
      like the ones which secure the eye straps up forward on the mast

      Deep down inside my little black rock of a soul,I whole heartedly
      agree with you Nels..............but I'm too lazy :-)
      Perhaps if you keep asking me a few questions at a time and take
      notes,over time you might be able to throw together a manual of sorts
      and market it........I won't even ask for a royalty :-D
