Is it possible to make a silicone recess ???, because I don’t want to put silicone were the starbursts were, and I want it to be O-ring like (like the FHZ silicone recess)
Yes, it is. It is fairly bumpy so you need a Steady hand or something to hold it in place but it worked for me.
I was going to try silicone it, but someone suggested to weave yo-yo string through the holes where the starbursts were, then place 2 medium Duncan spacers and a bearing. I tried it and it works great for me.
Here is a link to the discussion I made: http://yoyoexpert.com/forums/index.php/topic,5816.0.html I hope this helps.
