update if anyone was still wondering the outcome.
I have ordered 3 different strings from 3 different makers but to this point only 1 has arrived. I have also made some small modifications to the bow bolt system, my finger tabs, arrow shelf, and arrows. The over all outcome is good and most of the problem are gone or almost resolved.
1st. I found that there is (was) a void in the bow bolt system between the top of the bolt and bolt socket. I used silicon based mud to figure out the exact size of the void and then filled it with a cotton based foam. Filling this void reduced the high pitched harmonics a great deal.
2nd. The new string was made from the Mercury material (same as the original) but this one is an 18 strand vs 14 strand. I then installed (3) 2.5" pieces of paracord outer shell as silencers. HUGE DIFFERENCE!!!!!! over the 14 strand and cat whiskers.
3rd. I replaced the leather strike plate and shelf mat with protective felt used for furniture on hard wood floors. Another HUGE DIFFERENCE!!!!
4th. I started playing with arrow weight, brand, and arrow balance. First I tried the bowyer recommended arrow and arrow set up (Centershot 600's 50gr inset and 150 tip) I got 2 out of 5 attempts to actually stick in the target, the other 3 flew so weak nock left they wouldn't stay in the target. A buddy gave me a Axis traditional arrow test kit with some Ethics inserts with sleeves. The 400's at 30" with the 110gr Ethics insert/sleeve and 150gr point bare shafted like lasers out to 20yds.
At some point while I was playing with the bow bolt, string, shelf, and arrows the arm striking stopped and the face striking was now just a light brush. So I tried one more thing and changed the thickness of leather on my finger tab from 2 cordovan leather pads to just one. (this tab is a home made version of a Yost) Now this thing is dead quiet, smooth, accurate, comfortable and kind to shoot.
In 38 years of my archery journey I have never worked so hard on a single bow to get it to shoot well "for me". I guess I have always been lucky and just been able to tune some arrows and go enjoy a new bow. I still don't think some of the things I've had to do should have to be done to a new high dollar custom bow from a very well know bowyer. However, now I think this just adds to the partnership this little piece of wood and I will have for years to come. It is truly a one off custom bow now.
Thank you to all that gave me suggestions resulting in the ideas that helped me figure this thing out. The Tradgang family truly is a great one.
