I probably could use a tin can and a funnel?
Milo and I both modded our Rossi RR45's into doserless models. I'll show you next time you're over.
something like this?
I did run across a thread that might be of interest to you (Still have the KitchenAid?)
http://www.home-barista.com/grinders/modifying-kitchenaid-proline-to-hold-mazzer-mini-burrs-t2811-30.html#p75344
I've modified a couple of Prolines and there is a bit more to it. I didn't notice in the thread any mention of drilling and tapping due to the screw hole placement. The area where the stationary burr sits needs to be ground down to allow the burr to sit flat and center hole of the burr is filled with the material of your choice. A problem on at least a few of these grinders is a warped auger or warped moving burr backing plate (aluminum). Easy enough to remedy on a lathe. Even with stock burrs, the two I worked on would not allow the burrs to zero as the rear of the auger bottomed out first. That was also taken care of on the lathe.
Comparing to the Zip, Macap and the Bunn LPG commercial drip grinder sitting around the house, the Kitchenaid comes fairly close after the mods. However, unless you already have one sitting sitting around and like to play, I'm not sure it's worth it. We like it because of the build, looks, size and zero static cling.
And also, I like to mod things.
