I was given a 20 year old Hoyt Mystic Rebel xt. First thing I did was take it down and learn how to put it back together and tune it. It’s not precise but getting there. I don’t have a way to paper tune it now that I’ve put a drop rest on it. I’m hoping to learn if there are cams or limbs that can be put on this bow to increase its draw strength. Maybe 1 of you has done something similar or can point me to the right thread. I’ll keep looking.
Cardboard box, cut a square you can shoot 10 or so arrows through without crowding them, use Reynolds freezer paper and tape it over the hole. You now have a paper tuning setup. I use the painters blue tape. It holds really well when shooting, but pulls right off when you want to change the paper out. I tuned my arrows from the ground up with this setup.
