Hickory "run-outs"??
« on: October 22, 2011, 03:04:34 pm »
  When dealing with hickory board bows, is there an acceptable number of grain "run-outs" you can have in the board and still make a good bow if backed with rawhide?

I haven't made many board bows but the grain on top and on the sides has to be considered. If you have a runoff that comes to a point on the edge(top and side grain) it will probably be a problem. With a wood backing it would be less but even with rawhide the side grain can lift a splinter along the edge. A pic would help.

The angle on the run out is what is important !
Hickory will take more than most of the others !
how far down the limb to how far across the limb does your grain run ? How heavy a draw weight you doing ?

2 per lim for 50-55# max. If there are more, back it with silk linen or burlap.  Jawge

  I plan on making a wide over built flat bow, 65 inches long, somewhere around 2 1/4 to 2 1/2 inches wide at the fade.  I am not sure if I want to go with a pyramid style limb or run it parallel to just past mid limb and taper the sides from there to the tips.  It's just in the planning stages right now, but I would like to end up with a bow of about 45 pounds at my 27 inch draw length.

  I've never made a board bow. But I'd think you sure would want any run off. PAT problely right with a wood backing you'd less likely to have a splinter.

Backing it with rawhide will allow you to use a pretty nasty hickory board and still make a great bow. I wouldnt concern myself unless the run outs are at a sharp angle and/or if there are plenty of them. Put the "best " section of grain on the bottom side and build away man!

  I took a super close look at the hickory I plan on using for this bow.  There are absolutely no areas where the grain comes to a point on the corner edges.  And it appears that the actual grain on the sides of this piece where I think there is "run-ups" or "run-outs" are no more than 5 degrees to the back or belly.
