Modifying a Capresso Infinity for stepless grinding

Modifying a Capresso Infinity -- and side note: I'm told that in recent years Capresso updated the burrs on the Infinity, so maybe that's why the various reports on the Infinity as to whether it will do espresso grinding well enough -- is drop dead simple.

Note: I did this on the ABS plastic version, so YMMV with the stainless steel version.

1. Unplug the grinder from the wall. Seriously, don't want anyone getting hurt here.
2. Remove any beans from the hopper and pull off the hopper off, as if you were going to clean the thing. (In fact, cleaning the thing while you're at it is probably a good idea)
3. Pull out the ring burr (aka the "upper burr"). Set it aside in a safe place. Be careful not to drop it or bang it against anything, because you don't want to dull it up.
   
4. Turn the grinder over. You'll notice 4 'pry' points that are present as notches. Stick the back end of a spoon in each of the four pry points and pull on the top. The whole top will come right off.
5. Inside the grinder, you'll see the grind chamber. Attached at the top ring of the grind chamber is black plastic guard. Note the position of the guard in relation to the two white posts alongside the grind chamber. Gently pull this off the white nylon adjustment collar.
6. Remove the white nylon adjustment collar itself. That's the ring with all the holes in it. There are (I think) 3 clips that hold the thing in place. You can gently pry them with a table knife if you need to to remove the collar, just be careful not to break them.
7. Looking now at the top of the grind chamber, around the outside of it you will see the previously mentioned two white posts that stick up. In one of the posts, you will see a spring and a ball. These are just sitting in the post, if you turn the grinder upside down and shake, they'll fall out. Just make sure your hand is in place to catch them so you can reverse this mod later if you need to.
8. Put the collar on and the black plastic piece guard back on it.
9. Put the lid back on carefully, noting the position of the guides on either side of the bin/portafilter basket holder. These guides will help you get the top back on correctly. Pull it back down until it slides into place
10. You're done! Congratulations! You now have a stepless grinder.
