Intro: Chemical Mixer
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.
