1/2A History Lesson
Sorry if I'm duplicating someone's post here (I thought I found it somewhere else, but can't find the original link).
Seeing this last night shocked me to see how far back my memories of this hobby went. The Leisure Dynamics entry was earlier than I remembered. It was a good, fast read.
Enjoy!

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.

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.

Re: 1/2A History Lesson
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

Re: 1/2A History Lesson
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.
