Builders: Square engine, Over Square, or Under Square for you?

I knew all this stuff when I was a mechanic and machinist and stayed with it, but I've been out of touch professionally for a long time now. We all know how out of touch mentally I am.

Use it or loose it what I was told.

I write stuff down now. If I don’t make a too do list, I do nothing.
My library still yet grows.
