I think the parallel legal thinking is this: it's up to the patent (copyright) holder to defend the patent (copyright). That means they have to issue fair warning that the patent (copyright) is being

If the light goes on at variable mileage, but always in the 12K miles range, my guess is that the computer is tabulating the time the engine is running or is proportionally factoring mileage and runn

You're quite right about that. I'd forgotten that they are closing plants in the US (there was some hubbub about one of them in Ohio being cut back noticeably a few months ago). Cheers. -- Michael D.

Apart from what else has been said, be sure to check the rules governing materials for cages. Some rules do not allow 4130. It is stronger, but also somewhat more brittle. If there's sufficient loadi

Quite the case. Vulcanizing changes the composition of the rubber from a thick liquid to solid, and there's no easy way to change it back again. The combination of sulfur, heat and pressure modifies
