Thanks! I didn't realize the flexible cutoff wheels could cut through the brass. Did you use a grinder attachment for the smoothing?

I used a 2 1/8" hole saw on an unpressurized Saeco (Starbucks Barista) PF and a drill press. Worked OK, improved the crema 100%

It seems that a lot of people use the 2-1/8" hole saw because it is more readily available.  I believe it is the standard size for a doorknob.  However, iirc, a 2-1/4" hole is required if you want to use a triple basket.

I used a 2 1/4" holesaw.  Don't need to buy an expensive one.  The one for wood which costs about $5 will do it easy.  I didn't use a drill press.  Just be careful, line it up good and let 'er rip.  Worked perfectly.  And, yes, 2 1/4" is necessary for the triple basket.

Caffeguy,

I was looking into doing this to my non-pf saeco too.  I did not think it could be done since most of the handle thread would be removed as well.  Can you post a picture of the your pf?

Regards, Mark
