Title: raising poundage?
Post by: larze_fat on December 14, 2010, 11:07:47 pm
I have a hickory backed cherry bow thats 60 inches tip to tip, it curently is at 30 to 35 lbs, i was wondering how i could raise it up to the 50-55 lb range.

What draw length are you drawing?  Sinew or piking the tips. If you sinew ,then you would have to re-tiller and possibly lose some of the gain.  But doubtfull that you would increase 20 lbs even if you pike it and sinew. Maybe best to past to someone needing a lighter bow and make your next bow ;)

Either add another hickory backing or an ipe or osage belly and glue it up in reflex.   I increased a 60" static recurve from 47#@26" to 55#@26" by adding a thin(1/8" to 0 taper in 18") argentine osage scrap that David Knight gave me.

I tried backing a bow with linen flax to raise the poundage a little. Maybe I didn't apply it properly, I don't know, but that did nothing for increasing poundage.  ??? I thought I read somewhere that it would increase poundage, but I have been wrong before.

Your best off to start over from scratch. That kind of draw weight/length out of a bow with a cherry belly is just asking for trouble. Cherry is not that great in compression. It will almost certainly fret under that sort of stress.
