 I made my Microcasa bottomless p/f using a hole saw in a drill press. 
Dressed it with hand files & it looks professionally done. P/F was clamped 
in a vice securely clamped to the d/p shelf. Also opened up a La Spaziale 
bottomless the same way when I went to a triple basket. It's not rocket 
science but you do need to exercise common sense & take the same precautions 
you should be using around any power tool.
