I know this is risky. I just want to see if anyone has ever done this. I have a 1996 Hoyt Raptor bow. I'd like to add a Vibekiller side mount string dampener to dampen the string vibration. I do not have any rear stabillizer holes in my Riser. The onlty rear facing hole in my riser is an offset hole used for the cable dampener slide thingy. My riser is not machined. It is either cast Aluminum (likely) or cast Magnesium (doubtful.) There is a lot of metal on the lower riser area. I think I could successfully drill at 1/4" hole using a drill press, through the riser with no ill effects. What do you think? Crazy? Dangerous? Do-able?
