  1. It's been a busy couple of months, heaps of progress.

    Pin and cap rails installed, lower masts completed, lower yards shaped.

    The steps up to the poop deck don't look right from some angles, very awkward to get right as the decks run off in different directions, nothing is nice and level or square.

    The size of the lower yards surprised me. They extend past the rails 5-6m either side.

    I've noticed a nasty problem with the 2 lower fore stays from the main mast. The rigging plan shows them running under cleats on the fore mast then to their deck fixing UNDER the forecastle deck. Just to complicate things, there is a windlass for the stays to go over. This is what happens when you start something with no real idea of what you're doing. Another "teaching moment".

  2. Where I'm currently at:

    Note to self: stay focused while shaping masts.

    This started a series of mistakes, it took 3 attempts to arrive at the finished items. The second pair were correct.....until I followed Underhill's advice to check the sizing of the mast above before committing yourself on the lower one. I'm becoming quite proficient at manufacturing masts from square stock as a result.

    The "lug" on the cap for the crane caused some problems, snapping three 0.5mm bits or off centre holes on the underside while trying to drill holes for the crane pins. Drilling 1.04mm holes through the brass and brazing in 1mm tube sleeves with 0.5mm ID worked a treat.

  3. Thanks Phil,

    I've had a look at Wefalk's work, amazing stuff at that scale.

    There is a "tipping point" with twisting. Too much and you end up with cable. I'll try using the rope walk, it may give more control over the process.

    The copper "chain" blackens quite well after it has been annealed to remove the protective/insulating coating and soften the wire.

  4. Persistence has it's rewards. The book linked by Highwayman (Rudimentary treatise on masting, mast-making, and rigging of ships by Robert Kipping), if I've understood it correctly, provides sufficient information to work out the chain sizes.

    This knowledge has created problem.....the smallest chain obtainable afaik is up to 42 links per inch, which works for the bobstays and jibboom shrouds, but not for the sheets etc.. These range from (if my reckoning is correct) 65 to 106 links per inch at 1:60.

    Any suggestions on how to imitate chain at this scale?
