I was cleaning the group with JoeGlo and decided now was the time to go after it with a countersink bit. Countersunk the piece above the screen and used a vise to press the screw to seat the screen. 20 minute job. I'll report back on the effectiveness.

Very cool. Though their must be a flat, like sized screw that one can find at a local hardware store. Thanks!

M5 x 12mm stainless steel again. Sure is a big difference from that first pic. My only concern is I was getting used to seeing the screw head imprint to tell if I was getting full puck expansion. Ironic, huh? We'll see how it goes. :) (Click for larger image) back to top Jeff_K Senior Member Joined: 7 Jul 2005 Posts: 1,426 Location: Chicago Expertise: I love coffee Espresso: LaCimbali Junior D/1, 60s La...

Posted Fri Mar 14, 2008, 10:38pm Subject: Re: Silvia Dispersion Screw   Wouldn't it also work to further countersink the dispersion piece and then just mount it all back to the group and let the new M5 screw form the dimple in the screen?  I'm just mentioning that if someone doesn't have the equipment to press as you did.  Might work that way. Edit - forgot to mention nice work...you'd think they should just come that way from the factory. back to top BradS Senior Member Joined: 11 Jun 2007 Posts: 32 Location: St Louis Posted Fri Mar 14, 2008, 10:39pm Subject: Re: Silvia Dispersion Screw   Wow!
