1/2A History Lesson

Very Nice of you to hook us up to that article. Great reading and lots of information to boot.

Wow, good stuff. Saved it.

Only engines listed that I don't have are the Canuck, O&R Marine, and the Wasp (I think). Even have the Arden Plug.

Wild stab at it but Tem-Trol might be a shortened Temperature Controlled

Yes, I remember reading that it meant temperature-controlled machining. Not sure about the details, probably had to do with the temperature of the cutting fluid.

Temperature control or TCC, Was used by Cox in Santa Anna, CA. Also used by K&B/Veco. It is a process where the bar stock is kept in the exact same temperature as the Machine shop. This prevented variances in tolerances, and measuring, due tae temp differences. This is important when ye machine parts with micron tolerances

I have a friend who owns a high end CNC shop in a nearby town who had recently acquired and installed a new piece of equipment. They had to allow the it to sit for at least 72 hours before they could calibrate it -- as noted above, to stabilize its temperature to the ambient shop temp.

I really like the inked illustrations used in many of the ads -- done when draftsmen were craftsmen.
