longbow layout problem
« on: January 10, 2011, 07:59:00 PM »
I have BBO build going and my geometry must be off. Th long string is tracking to one side. I looked at it from the tips and it looks like I have one side of the limbs almost straight and the other side angled from the center of the grip. The angled side is the one where the string tracks toward.

What glue did you use?   You can't tell how the string will track until you put on a short string. Make it a 3" or 4" brace height. The long string is only to get the limbs bending evenly and together but only out to about 8" of tip movement. From there, if all is OK go to a short string and low brace.
  Got any pics?

TBIII. It is tracking off at about 2" of brace. Been looking at it over and over. It is really obvious. Due to some sideways slippage during glue up I had to cut more off of one side of the riser.

The result was an almost straight limb profile on that side while the other side is angled towards the tips. I think I can clamp a straight edge from fade to tip and get it fixed. will lose an inch off of each end probably.

Can you post pics?   One from end to end would help. Maybe one braced and one unbraced from that angle.
  If all else fails you can heat the bow up to 150deg(F) and the glue will release. I have done this with hickory backed bows but boo should work fine too. Just start at one end, heat it and get a chisel or flat tipped screw driver between the two and work down the limb adding heat as you go.  Once off you can clean up the glue surfaces and reglue.
  If you tape your components together after glue up but before clamping it should help keep them from slipping.
