@Piloter: Don't be the farm on you not seeing it in your lifetime. Plasma torches, CNC Mills/Waterjets, Rapid Prototyping, and really spectacular computer diagnostic systems have all percolated down in the last 10ish years - I have very little doubt that there will be at least a niche demand for being able to do this…

There is another thermal spray process that's even cheaper but Daimler has the patent. The wire is held in the center of the cylinder and a massive capacitor (~20k F) discharges and makes the wire explode and deposit on the wall. Pretty cool but the main problem is the it creates something like 170 dB when the wire…

@Adam Spano: No... Respray and rehone.

Reading through the technical brief, I had a realisation of sorts that people are becoming less and less patient.

@TR3-A: Don't worry about rebores. This technology is simple and affordable. Auto machine shops will have it on site or can have it done.

This technology has been around for quite a few years. I recall first reading about it in aerospace journals a couple of decades ago. The process can literally spray any metal on to any surface. One ad for a company who sold the equipemnt showed an apple sprayed with some metal, tungsten I think. The apple was…
