Title: Finding the brace sweet spot
Post by: huntin_sparty on August 22, 2010, 10:40:00 AM
I have been working with a new to me Morrison ILF mini 14 riser and TT black max carbon wood limbs long to find minimal vibration and noise.  I was up to midnight messing with it I went from 6.5 to 7.25  recommended is 6.75 to 7 with the best so far being 6.5 ish but still some noise and more vibration than I would like.  I am newer but anything else to do other than add or remove twists to adjust BH?  Do some set ups just not get a sweet spot?

What would it shoot like at 7.5" or a little more? worth a try bud.

Are you sure you have your arrows tuned before starting. Maybe that would help. Sometimes by the time you take a string off and re-shoot the bow it is hard to notice a difference. I like to shoot through a conograph and have a sound meter and make a chart. I have done quite a few bows and have always found a difference even if I might not notice it by having to listen after the time lag of changing the string.

Sweet spots are where they are...you just need to find them. Since you are shooting an ILF bow you might want to tinker with the tiller a bit. I have found that on my DAS riser, no matter what limbs I have on it, it shoots best for me with zero tiller. Good luck and have fun. It's almost hunting season.

Good points HB3.  I don't have a sound meter or a chronograph.

I'm not sure that I can always tell by listening.  Subtle differences in sound are hard to detect, especially if you are losing some of your hearing.  I haven't checked into sound meters, but I would think they would be a good tool for this.

I work mine to what I can detect as a low noise spot, and consider that as a starting point.  Then it might take me a month of adjusting and tweaking to get to what I will finally settle on as the best spot.

Its funny cause I was getting frustrated keeping track of which brace seemed best.  So I set up a recorder and set it right in front of me shooting, and the only thing I heard on the recorder in a certain range was the thwap of the arrow hitting the target.  Even in that range I was hearing noise when is wasnt there through the feeling more handshock than I am use to!

On my ILF,I went through the same as you recently.I messed with the tiller and mine is a hair 1/8 positive and at my 25 in draw 7.5 works best for me.I even adjusted the lateral setting alittle to make sure string is centered.My ILF is only 54" and it shoots like a dream for me now.I love to tinker and it is cool to be able to fiddle with all the settings.This bow is fun to shoot.Enjoy.These bows will not only shoot great but they have a way of encouraging you to buy more limbs to try.  :biglaugh:
