Steve — I’ve never heard of using silencers to tune before. But considering the source (I won’t embarrass you here by mentioning your considerable credentials re engineering), I’m game to give it a try. I would presume that the heavier or bigger the silencer, the more influence its position would have on tuning?
So, now we have three incredibly simple ways to fine-tune a bow to arrows: brace height, depth of arrow shelf, and string silencer position. I’m anxious to try it but since I’m all tuned-up for turkey I’ll have to “invent” some slightly untuned arrows to experiment.
Thanks for the tip, which may be decades old but living in a cave as I do, I’ve not heard it before.
