i am doing this mod and came across a problem that i dont have and cant find a drill bit small enough i have a 1/16 but it seems like it will have to much slack it gives .015 clearance. that seems like it will make the wheels rock and it should have more around .03. I have looked in many places but all i find is 1/16 i know they make smaller of course and brownells sells them but i dont want to wait for shipping. So if any of u guys know a chain type store that will sell them plz let me know (like a home depot or somthing along those lines) Thanks
