The injector section was cut like you say with dremel then filed and sanded etc.

It can of course be done. But for the time, effort and money saved now days there is no need when they are on offer for such reasonable prices.

Also doing it by hand will take ages to match each port the same. Even done by machine all my plates are finished and checked by hand.
