I was told that if you have two recurves the same length one has a 19" riser and another has a 14" riser the14" would have less finger pinch. Is this so? If so why? I just can't wrap my mind around this.
Thanks
Good question for a bowyer. It seems to me that it depends on where the tips are at full draw. "Super recurves, like Border CHs will open up more than a static recurve or standard recurve and have less pinch....or so it seems to me. Now, for bows of the same length, and with the same limb design, your friend could be correct. But, I think it would still depend on the tips coming to the same spot on the two bows.
There's lot of variable that will effect string angle other than riser length. (are the tips static or not? At what angle is the back of the riser cut, nearly flat like a Ben Pearson, or extreme like a Bear 48 mag? What is the taper rate of the lams? how wide are the limbs?....)
Thanks. I thought it was a generic statement.
Ya see... Traditional Archery is simple sport... :dunno: ...
I would think the limb length would pay a factor in finger pinch.....but that's just a thought.
Everything else being equal, the more limb you have working (besides the tips) the less string angle you have.
If both recurves had the same limb width and thickness than the one with the longer riser and shorter limbs will have to do more work towards the tips as it's drawn back to compensate for having less limb to work with which will result in an increased string angle.
The recurve with the shorter riser should have more inner limb doing the work (since the limbs themselves would be longer) with the tips doing less work at the same draw length as the other bow which results in a decreased string angle.
At least that's what I've been led to believe.
