How do you pop the caps off of a Loop 360 without causing damage? I want to add more weight to them by popping the caps off and putting flowable silicone on the inside.
Get a strip of duct tape and put the center of the strip on the cap. Grab the two ends and just pull it off.
You might do better using #10 solid solder for the weight. It’s easy to form into a circle and push into the shell.
Widen the gap (or use thinner string) and then add lube, or use shorter strings… should have more kickback (will feel as if it’s heavier) without altering the yoyo weight.
