Yeah most grinders like this have some sort of ball/spring that click into detents to hold that setting. I took my Infinity apart and removed these parts so I simply spin the hopper where I want the burr alignment to be and it's stepless. Not rocket science, but it does have pretty much an infinite amount of settings. Instead of being stuck with marked settings that click in place you can really fine tune the grind. Only thing I don't really like about the grinder is the way the grounds are retained on the carousel (under the lower burr). I'm going to modify that part so it sweeps the grinding chamber, instead of the grounds being flung away all over the place. It's not my primary grinder, so I haven't taken the time to do it, but will let you know how well it works and possibly take a few pics. Later!
Yes. Was this an older version that was modded? The screws look like torx type, but they don't appear to be a standard size on my torx wrench set. Maybe you modify the settings from the top of the grinder? I would be interested in more detail.
The Infinity I took apart is about 2 years old. It does have those weird Torx screws with the little knob in the center of them, but I bought a set of Torx drivers with a hole in the middle of each one for screws like this. I simply took it apart and removed the ball/spring and this allows the hopper to be turned in any direction with no clicks to bother with.
I've been thinking of coming up with some sort of sweeper system for the grinding chamber so the grounds retention is minimized. That's the only problem I find with this grinder. The burrs are nice, but a lousy grounds delivery system.
How well does the Infinity work with Silvia? Later!
Interesting. So you removed the bottom rather than the burrs? (There are 3 ball bearings beneath the lower burr, I assume these aren't the same bearings you refer to. ) I guess I just need these special torx drivers--do you remember which size you used? The hole in the driver must allow for a little play if the size isn't standard? Thanks for the info.
Yes, I was told by many people that the Infinity wouldn't work with the Silvia. I don't find this to be the case, but I made sure to get the LM baskets which help. The only issue is that almost every espresso roast comes in between clicks, but it seems like this is pretty easy to work around. I just, for example, grind 1/3 of my dose the 3rd lowest click and 2/3 of the dose at the 2nd lowest click. A tad annoying, but maybe this takes me an extra 5 seconds? No big deal, but it would be nice to make it stepless since it sounds easy enough to do...well once I get that damn screw off!
Yeah I removed the actual metal housing. I have the metal bodied version and it's held in place by those Torx screws, same as the lower burr, just different size I think. I remove the lower burr every now and then to give it a good cleaning. I'm going to modify the carousel (nylon part the grounds fall onto) to give it a sweeping effect. Instead of the grounds falling onto it and then being slung down into the chute, I plan to modify it so the grounds fall onto the grinding chamber bottom and then get swept out, like I've seen on many conical design grinders.
Just checked the size..... the burr screw is a T20, which you might already know. Can't tell you the size of the 4 housing screws. They were Torx, but when I was able to get them out I installed allen head screws of the same thread size.
If you get the housing off you'll see a place where there is a steel ball and a spring. This is what lets the collar click in place for each number. I simply removed those 2 things and now I move the hopper exactly where I want it and that's it. No more steps.
I had thought about using the burrs from the Infinity to make some sort of hand grinder. Mount the lower burr on a shaft supported by ball bearings with some sort of threaded mechanism to make micro adjustments, make the upper burr stationary and make the adjustments by moving the lower burr up/down. This would allow the grounds to fall straight down and would leave nothing behind. But for the cost of most hand grinders it might be more trouble than it's worth. Later!
After cleaning out the grinds and re-inserting plastic (poor design) hopper, the corner ends on the bottom of the hopper snapped off. I believe it still functions good enough for my Gaggia Classic. Where's a good place to get one?
Only place I know of is directly from Capresso. A few years ago I was washing the hopper for my Infinity and having slippery hands caused me to drop it and that snapped the lip off the bottom. I think it was only $5 and shipping.
I will probably post this in the Buy/Trade section....... I'm going to sell my Infinity (metal bodied version) and the first pump machine I had (CapressoBAR 351) so I can buy a nice hand grinder to match my Cremina lever if you know anybody interested. Later!
I found that when this happened you could set the hopper on like you normally would & then turn it clockwise until it drops in & engages with the slots. Once it does then turn it back to the normal install position & the burr should lift out again.
