Title: 3pc td longbow stack height?
Post by: styksnstryngs on January 12, 2019, 03:20:12 PM: Hey guys, I'm building a fairly curvy three piece hybrid. 15" riser, 60-62" ntn. Tips will be about an inch ahead of the front of the riser. What's a baseline or a range for stack height with 1?5" wide .040 bearpaw clear glass if I'm shooting for anything between 42 and 50 pounds? I'd rather go a bit heavy with this, especially since I can trap down weight. I also think I'm gonna keep the taper rate down to .001" and add a tip wedge but have a pyramid limb.

Post by: kennym on January 13, 2019, 07:34:53 PM: .002 taper may produce a slightly heavier bow. My SWAG would be .330 for 50# on a 64"

Post by: kennym on January 13, 2019, 09:10:31 PM: Correction! I looked again and it is .325 for 50@28
