Looking for a Machine shop near by to remove 1/8" from the inside of this American Turbine 6" extension.

Santa Clarita - San Fernando Valley - Maybe further if necessary.

You can see the 1/8" lip inside, even with the slight obstruction coming out of my Aggressor 9 vane bowl the boat really likes it. Don't want any obstructions.

Should be able to put this on a lathe and knock it out pretty quick, 6061 aluminum.
