I just recently started to enjoy a cup of coffee in the morning. I had a "helicopter blade" coffee grinder for years and decided to upgrade to a cheap hand-crank burr grinder (Kyocera CM50 - $39 on Amazon). This grinder has conical ceramic burrs that produce a MUCH more consistent grind for drip coffee than my previous grinder. I was astounded that I could actually taste the difference - much smoother once I found the right grind setting!
I then started looking into motorized burr grinders. Most high quality grinders were $500+. The cheapest conical burr grinder I could find was the Bodum which was $80. Not bad, but I thought, why don't I make a burr grinder attachment for the KitchenAid mixer that's taking up a ton of my counterspace?
When coming up with the design, I held myself to these rules:
1. Priced below the $80 Bodum
2. Meet or exceed the grind quality of the Kyocera CM-50
3. Able to be made with tools a "tinkerer" might have - no fancy CNC milling machine parts
4. Easy setup/removal (less than 15 seconds each)
NOTE: I designed this for my Kitchen Aid 600 mixer I have a design in mind that would work for all other square-drive Kitchen Aid mixers and will post shortly.
