Ok Aiph5u! You are extremely knowledgeable and resourceful without a doubt, but damn if you are not killing my wallet! 
Those look pretty awesome, and I love how the avoid tearing up the holes with the split shaft and a 5 degree angle. I am keeping those in mind for sure if I start having problems with my milled ones. I am going to try to make my own first and give it a whirl (hopefully “whirl” doesnt end up referring to my stock. 
)
Thanks for these awesome ideas!
