I have some problem when I try to used the tapered buff I got with your wheel smoothing kit. Maybe it’s me who doesnt install it the right way. I simply slide it on the tapered adaptor as far as I can but the adaptor is only half the length of the buff so the upper half has nothing to hold it straight. So when I try to use it on a drill I got way to much vibration and the buff deform itselft. What am I doing wrong ?
