I am looking for advice on how to reduce grinder static in my pasquini moka grinder. I have been dealing with flying grounds for awhile now but it has finally driven me to the edge of madness with grounds flying everywhere when I dose.

It's not a settled topic, and this is second hand stuff (since nobody is replying first hand). In many cases the problem is with new grinders and goes away as the grinders break in. In some cases, grounding the path where the grinds are going eliminates the problem. Finally, there's a device still made that originates from the old record days, the zerostat.

Wow, Jim, I have one of those!(somewhere)
I purchased it back in the late 80's when I had time to be an audiophile (Mark Levinson, and AR tubes, Magnaplanar, Linn Sondek, etc) RECORDS!!! :lol:
I wonder how long the shelf lif is on one of these. Gotta go to the basement and try to find the dang thing.
My doser-less modded Rio SJ already has a some static charge. I can only imagine this winter with 20f temps, and 30% humidity.
So, assuming the OP and I have a Zerostat in our trembling hands, where do we discharge?

I'm still running some Maggies in my living room, and I've got an old Harris Broadcast C-12 to make my records dizzy! Let me know if you want any of 'em!?! ; >

I couldn't find the alt.coffee thread where this was discussed, so you'll need to rely on my memory. That version is to zap the chute and/or doser with the zerostat.

Sorry, I can't come up with more.

I do have one reality check. Fine particles make up at most a 1/2% of the grind by weight, but about 20% of the visible surface area. In other words, if the static is mainly affecting fines (i.e. the sticking stuff is a fine powder), you are very likely thinking the problem is a lot more serious than it actually is. It could be that it's mainly a cosmetic, housekeeping type thing.

Static is not terrible, even for the doserless, but I know it will be in our extra dry winters here. The hair in my nose feels electrified :lol: Sorry. :oops:

When I received the grinder, the Mazzer little wire thingy (well most of it was already installed...) a little piece had been broken off.
I some ways, doserless is cool, especially when utilizing the WDT...grind falls right in...just a tap on the funnel gets the clinging grind off the inside, and no grind clinging to that stainless cover piece in the doser...hated having to brush that each time. The doser did provide less clumping, of course, but the WDT takes care of most of that.
