[Winky Dink]

The basic process is to make a split mold of a dog bone, put some epoxy putty (or Bondo) in each half of the mold, then squish the halves together with a new resistor inside. Most of the time the new resistor is smaller than the old dog bone. If it's a low-wattage dog bone, then my 1-watt resistors might not fit. Then I either shave off some of the jacket of the resistor, use a 1/2 watt resistor, or use a mold from a bigger dog bone. I think this is a well-known process, but I have a lot of photos and I can put a photo demo together.
