Its my month for finding odd stuff .

Whats the history on this . I know it heats up tire patches . Did they
patch tubless tires with it too ? What age is it ?



I've never used one of these hot patch setters, but I've seen them used. They
are used to press the rubber patch onto inner tubes after it has been heated in
order to fully vulcanize the patch to the inner tube. I don't think they are
used on tubeless tires any more, although I saw them used on some years ago.
The procedure was to clean the area to be patched, then use a rasp to rough up
the tube, and then apply a rubber solvent to the tube. Finally, the patch,
which contained a flammable layer was applied and lit with a match. The clamp
was then tightened over the patch to complete the vulcanizing process.
Don't think I ever remember a patched inner tube failing, at least not where the
patch was applied. I have had two tubeless tires fail after being fixed; one
bias ply tire and one radial... the plugs they use just aren't really
vulcanized to the tire like the hot patches were.
