For experienced bowyers out there, I'd like to take about 4 pounds off a hybrid longbow with trapped (angled) limbs.  Have done this before with straight-edged limbs (Hill bow...counted sand strokes and checked tiller as I went, worked fine) but on trapped limbs should the sanding angle follow the angle of the trap or should it be 90 degrees to it (i.e., the same sanding angle as with a straight edge bow)?

I would take some off of the sides (Narrowing each Limb) as well as some off of the Trapped Surfaces.

Thanks Carbon C, but how much would be 'some'?  Maybe 50/50 (sides to trapped surfaces)?  60/40?  80/20?

I would take 2# off by sanding the sides, and then after that was done, I would finish by sanding the traped surface.  Go SLOW and Stay Consistent.  I just got done taking 7# off of a longbow by trapping it.  It had a slight trap to the belly, and I ground @30degree trap on both limbs from the fades to about 6" from the tip.  I was going to refinish the bow anyway, so I sanded the back and belly lightly as well as rounded all the glass edges.  I couldn't be more pleased.  It is a better shooter now to my non scientific "feel".  4# should be pretty easy.  BTW I would stay away from the last 4-6" of the limbs when you reduce it.

Get to it!!!

Sounds good CC, I appreciate your advice.  Time to sizzle some sandpaper...
