The tired old warbow (80# @ 28# max 32") is now about 45# @27" . It needs a string making for it, the nocks polishing and to be shot... maybe it will shake itself to pieces!?
It's looking good for now considering it was just an experiment.
Update:- I made a string (I haven't done the centre serving yet) and took a test shot. It was unremarkable, no vibration, rattle or shock. Very smooth and shot like any other of my ELBs, it was about an inch above and left of the scrap of masking tape on the boss that I was aiming at.
