In this Instructable we will build a small mixer just perfect for those small jobs. This is the mixer I used in my project titled Laying Your Own Eggs, so to speak.
- 3/8" threaded steel rod - 6 inches
- 1" x 4" x 1/8" flat aluminum
- Two (2) 3/8" nuts
- Cut-off saw - or hacksaw
- Electric drill - handheld, drillpress, whatever
- 1/8" and 3/8" drillbit
- Metal centre punch - or a nail
- Metal file
- Adjustable wrench
- Compound square - ruler or tape measure are fine too
- Eye protection
Step 1: Making the mixing blade
I am using a compound square here to give a clean square line. The reason I am marking so close to the end in the photo is that the end was rough and I wanted to clean it up.
The second photo shows all lines marked. The length between end cut lines is 4 inches. The diagonal bend lines are simply 45 degree angles from the cut line. Make your diagonals the same as shown in the photo to ensure proper mixing rotation in he finished tool. The squiggles on either end are simply the areas to be discarded after cutting.
Now would be a good time to measure the centre of your piece. I don't show it marked here because I forgot to do it until it came time for drilling.
In photo 3 you will see the flat setup in a mini cut-off saw. These saws create quick clean cuts in metal, but a hacksaw will work just fine. Use whatever you have handy.
In photo 4 I am using a small deburring tool to remove burrs left from cutting. Very handy tool when working with metal and should only cost a few dollars. Simply filing the ends works well too as shown in photo 5.
Your threaded rod can be cut at this stage also. Just measure 6 inches from the end and mark with a marker. Cut just as you did the aluminum flat, and clean the end with a file. That's it for the rod.
Now, let's move on to the next step.
