I purchased a kit from Binghams to make a 68" 60# longbow(.418). After seeing some of the R/D bows I have changed my mind from straight to a R/D design. I an planning on using a takedown sleeve and changing the design to T/D R/D. 1.25 D with about 1.25 R. The Tips are close to the back of the riser. What kind of poundage increase will I get going from the straight design to the R/D design. Binghams charts show their shallow T/D as .404 and .335 with the pronounced. My riser from fade out to fade out will be about 16". I'm wondering if I should just order new laminations.
Its hard to say what you need. You might try a thickness somewhere between the two and see what you get. I have found you have to build a couple to see where to go with thickness recepies.
So it is still a TD? Is the riser 16"without the wedges? If nothin changes in the riser section,I'd guess it would gain a few #.
Like Mike says,the first is an educated guess.......
The riser would basically be the same length as the normal riser for a Bingham Longbow(Not the T/D). I need to square up my form after cutting it to the shape I wanted. I an using the sleeve like 3-River's sells. I got my sleeves from Northwest Archery several years ago when I was in the Seattle area. I plan on setting up the sleeves like Wes Wallace where the sleeve that slides in will be the lower limb which would keep out water etc.
