What did you use to cut the portafilter?

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% -George

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. John

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
