Introduction: Chemical Mixer

About: Andy McLeod, Design Engineer. Creative studies major. I still want to save the world. Maybe I need a cape.

Does anyone still mix D-76 or other photochemistry in their kitchen? It doesn't disolve too well with the agitation that you can supply with your arm and a spoon. Making a stirrer out of 3/8" tubing was much easier than finding and buying one- camera stores are not what they used to be by any stretch of the imagination.

Step 1: Cut and Knot 3/8" Plastic Tube

The stirrer is just a 3/8" plastic tube, probably vinyl from home despot or similar. 2 feet is about the right length for stirring in a gallon milk jug.

A simple knot near the end makes a weight that will swing around when you spin the tube.

Step 2: Chuck Into a Drill

3/8" tube barely fits my 3/8" chuck. Make sure to size your tube to fit your tools.

Step 3: Rock and Roll.

This works much better than arm supplied agitation, a lot faster too.

HEY! DON'T FORGET TO FLUSH THE CHEMICALS OUT OF THE TUBE BEFORE MIXING A DIFFERENT CHEMICAL.
