This may sound crazy, but I've been thinking about this for other reasons..

I was just randomly looking into coating the doserless chute of an SJ, in Black Teflon, simply because I think it would look nice, and the surface would be a nice, slippery slide for those grinds. But then, I started doing some research and finding that Teflon is used in Anti-Static situations, for one reason or another, which I have yet to figure out.

So here comes the thought: Would coating the Doserless Chute in Teflon, help with the static issue that seems to be apparent, when the Anti-Static screen is removed?

I hate the screen because it causes clumping, I'd almost rather have a spray, of grounds than pebble sized clumps in my basket, which don't break up all that easily, and then I end up making as much of a mess trying to break them up.

Anyone know a place to get parts Teflon coated? I'd be willing to give it a shot.

Somewhere I have a small square of aluminium that has been Tiodized and handed to me as a sample. I don't think they do that process any more, but I got it back in '74 or so and still remember how amazingly smooth, hard and slippery it was. Never found a use for it, but never forgot the name either.

Ira,

I think that might almost be overkill... I'm also not sure on the process.

The reason I came up with this idea is because I found that a lot of anti-static products, were using Teflon, or PTFE which helped with the static issues. I was looking into the idea, simply because I was thinking about powder coating my Mazzer Doserless Funnel just to match the grinder better, then I came across the idea of Teflon Coating, with a Black Teflon, I figure it can't hurt, super slippery surface, plus possible anti static coating, may help with the over spray.

I've contacted several companies, and found one willing to do a $100 minimum order, I'm going to gather up a few parts, if anyone wants to join in and split the minimum order value, and play around with an idea.

Anyone have any thoughts on doing the Teflon coating in general? Anyone have any knowledge of PTFE coatings?

I would ask for a small sample of what to expect or at least make sure the person understands the problem. I've seen surface treatments for gears in racing transmissions that might be better than Teflon. Teflon is slippery, but not necessarily smooth. If the surface finish is not what's needed, you might find that you're worse off than before. Something like one of the following might also be the answer:

http://www.extremeion.com/whatisHCR.html
http://microblueracing.com/smooth-slipp...tions.html

And here's a price list for doing motorcycle parts, looks like you could probably try ISF for under $10.

sounds interesting...wondered why this has been done before. If I were closer I'd join in.

Seems I left the last link out!

Well my thoughts is that it's not just about being "slippery" but also that Teflon in some cases is electroconductive, and can be used as an "anti-static" coating. I've gotten a few responses on the subject, from coating experts, and they say that the version of Teflon which is formulated for FDA use, is not specifically formulated for the anti-static properties, but all versions of the coating, will carry some aspects of it. Really in all honestly, this was originally more an aesthetic thing, and I wasn't planning on going this route, but it seems like ti could be interesting.

As far as the links that you sent me, I will look into them for sure, but based on what they are geared for, one could assume, they are not FDA approved, which in this case, is a larger concern. (side note: if I got the chute powder coated or the likes, it would have only been the exterior, simply for this reason.... )

I don't think I'd worry to much about FDA, the odds that anything on the chute would come off when a bit of coffee slides by is likely zero. Besides most of what I posted is a process for making the metal smoother so things slide easier. I might try the polishing stuff followed by TiN coating if I was trying for perfection, and then I might just discover it was a waste of $100.

The only way I can think of to kill all the static is with something that gently blows de-ionized air through the grinder and out the chute.
