Hi, i have built a few bows and am still learning the trade. Please help me with the following.
- I am building a 58" boo, core, raiser, boo bow of 40 lbs at 24", my raiser is 12 1/4" long.
- I would need a min one inch raiser in order to cut in a shelf.
-I have fail on my previous same speccification bow as the fade out is too adrupt thus causing a bad hinge one inch after the fade out on both limbs.
-have been told to make the fade out more gradual at least 3 inches into the middle of riser and at the point 3 inches, the thickness should not be more than 1/4 "
-I find it hard to keep that 1 " raiser if I did the long taper in. And the profile of the raiser will not conform to the lams. Need help on this area.
secondly, after final tillering, If i cut in a raiser of 1.5 inch from the middle. Towards the fade out area, at what point does the limbs stops bending 1/4" 3/8" ........this will tell me how far I can cut in for the raiser from middle towards the fade out area.
Hope I have explain clear enough, if not please feel free to ask. Thank you for your comments.

Check out this link. Here is how I did it. That riser is 12" long and just over 1" total (the red riser wood). The sight window is just about 1.75" from back to belly.
