DIY Knob Repair (Updated Video Available)

How to fix a broken knob. You find these on stoves, radios, (old) TVs, cars (heater, AC, radio), gas grills, etc. With a bit of practice it takes about 15 minutes.
It's not uncommon for the shaft / ferrule to crack or break. I've used this technique to fix them and so far it's been 100% and never had to re-repair one. It's a very permanent and strong repair. I even used it on the splined ferrule "pot metal" window crank of a 1966 Mustang!

MATERIALS
Slow set epoxy glue (can use other glues, but they are MUCH less strong)
Thin tube (as discussed in the video)
Sewing thread, polyester is best
Scissors and / or knife
Sand paper
Spacer (drill bit or anything of the right size per video)

Note On the orange / bigger knob: I have also used a big metal washer rather than the cloth technique. The washer is faster and easier, but I did not have one and did not want to run to the hardware store. The cloth / epoxy thing works well for repairing broken plastic cases, but it's a lot messier and harder.
