Well, almost.

Consumer-grade stand alone burners, which virtually no one uses anymore and not many people ever did, require a "music" cdr and won't burn to a "computer" disc. Before bit perfect digital audio inputs were cheap, it was an economical way of getting your DATs/band demo/whatever onto your computer, even with the disc surcharge.

Likewise, virtually everyone I know in the DAT world used data grade DDS tapes instead of actual DATs. 60m (120min) tapes are identical and 90m (180min) tapes, while the actual tape is thinner, are well-tolerated on a large number of decks. Even consumer level decks had no way of knowing if you were using a DDS or a DAT.

A properly designed sand casting is defect free with proper quality control. Most of the sand that is washed ends up in the gates and sprue. Most of the surfaces (somewhat rough in a sand casting) are going to be shot peened and machined smooth anyway...

A foundry that produces sand inclusions in their castings without any quality control will not stay in business very long at all.

Diesel engines were originally designed to be run on plant (peanut) oil, not BD.

Old diesel engines can be modified to run on SVO (Straight Vegetable Oil) or WVO (Waste Vegetable Oil) but the high injection pressures and tolerances of the pumps and injectors of modern diesel engines do not respond well to the much higher viscosity of SVO or WVO, even after pre heating. The glycerides (which are removed in the transesterfication process to convert to biodiesel) left over after burning will gunk things up badly.

Modern diesel engines: Biodiesel=yes, SVO and WVO= no, if you care about the life of your engine and injection system.

Yes, because it's not like there's a government agency designed to test and enforce workplace safety. And companies surely love to expose themselves to huge amounts of liability, especially companies that manufacture safety equipment. I'm sure no one has ever studied the effectiveness of auto-darkening welding lenses. Now let me go extensively test my certified safety glasses and hard hat before I go back to work.
