    First topic message reminder :

    Hi All,
    I "carved" the beechwood down to about veneer thickness and it's still 'stiff as a board'.  That's okay because I've set it aside and a hazel stave is coming along nicely . . . I think; I'm nearly at the point of needing a tillering stick (has to be a milestone in the life of a crossbow builder).  I'm going to try, if it doesn't become too time consuming, to work in a wippe-like addition to it.  It will provide some measurements for when the time comes to make the one for the finished crossbow. 

    Anyway, Mac, I'm looking forward to what you have to say about prod width vs. thickness; I think it will be an issue very soon - if not already. 

    If anyone has experience with cutting new wood in the forest any thoughts would be much appreciated.

    This one pulls about 100 kg or bit more with 123mm power stroke ( 220#-250#/5" imperial)
    Wood Prods - Page 3 J_mk_1

    String is 48 cm.
    Bow is yew branch stave, 33x23mm mid-limb spread out legth about 60cm . Stave is steamed to brace-height deflex.

    Just scale that up about 35% and you get 26" wide bow with power stroke just under 7". Draw weight for same limb width could be up to 300lbs . So 180#/7" should be trivial exercise.

    Wood prods really benefit from high deflex. For given power stroke limbs can be about twice as thick as they would for a low braced, reflexed longbow type tiller.
