    Re: Treatment of old tarred hemp ropes

    Do the turps dissolve the wax? I found that turps, as opposed to alcohol dissolves tallow, which is a very nice feature of that substance.

    Very interesting, in the recepies (6) I've found, from 1899 to 1955, linseed oil (raw) is only mentioned in one, and it can be read as it should only be added when used on wood!

    Treatment of old tarred hemp ropes

    The term for this is "lappsalvning" in Swedish, the goo used is called "lappsalva".
    What is the term in English? Boat soup?

  6. Re: Sailing/rowing/motor sailing dinghy decisions.

    My point is that you cannot really deal with the bow raise.
    You either have to go at a relatively slow speed, or put enough power to get it planing.

  7. Re: Sailing/rowing/motor sailing dinghy decisions.

    Correct me if I'm wrong (I'm not a power boater) but isn't the bow rise what happens in-between when the boat is going at the theoretical maximum speed and when it starts planing, without any...

    Since steaming dries the wood, I'd soak it in water for a day or two, then resteam it and bend it with some extra support as nedL suggests.

    Re: door furniture

    12 mm seems a bit thin for a door, so I would use that for panel/s and make thicker frames. A panel door (is that the name for it) looks an awful lot better than a flat one too.
