So has anyone ever drilled/tapped their top plate for a new basket? I was going through my boneyard and found a old blown 15" audiobahn. Its got a pretty beefy magnet so i figured id recone. The cast aluminum basket is cracked so its out of the question. Im thinking about going with a 12" 12 point aluminum basket from psi. only problem is the original basket formed around the motor and bolted to the back plate. So i have to drill and tap the top plate to accept the new 127mm x 60 degree mounting pattern of the basket.
I figure if i leave the top plate attached and drill it i wont have to re attach it to the magnet (taping off the center to prevent shavings falling in of course). anyone ever done anything like this that can add a little insight?
