    Hi Everyone 
    I am tillering an ash lath to somewhere around 45 lb draw weight. The lath is 33 inches nock to nock (83cm). I know I could give it a draw of as much as 15 inches but I was going to go with between 10 and 12 inches. Any thoughts?

    That's playing it safe that's good. I think the 1/3 of the bow length determines the draw length is a good reference. Another rule of thumb I heard for bows was double the draw length + 10% which would be perfect since your bow is 33 inches long. But, I think it be definitely pushing it even though a overly long bow definitely has problems with slow arrow speeds but, so does a overly short bow since even though there's not a lot of limb mass there would be a lot of set which would reduce arrow speed or in this case bolts. Also since this is a white wood bow I think it be better not overly short since it might crystallize the belly which could eventually cause the bow to fail. What you might want to consider also is heat treating the belly it make it less prone to set and make it snap back faster. Also since the belly would be denser it would make it faster since you would have to take off more bow wood.
