Next, I had to keep the grinder assembly from falling out of the mixer.

The mixer comes with a 5/16" screw and the drill/grinder comes with a 3/8" bolt.



I looked around my basement for anything that could connect these two. Luckily I found some 3/4" aluminum bar that would work perfectly. But aluminum is not necessary. A few wraps of string, a bunch of rubber bands, etc would accomplish the same thing: Keep the grinder shaft from falling out of the mixer.



If you do want to duplicate my design, 3/4" x 1/8" aluminum bar can be found at Lowes, HD, ACE for less than $5. i would honestly recommend looking around for an alternate before buying the aluminum as this is a low-stress part.



If you like the design/look, here's the process I used

1. Look at drill/mixer top/down

2. Sketch curve on MIN 3/4" plywood (NOTE: Gentle curves/transitions are best! Sharp bends are weak/hard-to-form)

3. Cut plywood in half with jigsaw - following sketched line

4. Place aluminum bar between plywood halves - in vise

5. Crank vise until aluminum bar is bent

6. Drill 5/16" hole in mixer end of bent bar

7. Attach bent bar to mixer

8. Mark spot where 90deg drill intersects with aluminum bar

9. Drill 3/8" hole at intersect spot

10. Connect mixer to grinder assembly
