"One Perfect Part at a Time"

Measuring Up

image-aspxI was in grade school in the 1950’s. It was way back then at least as I can remember that there was a big deal made about using the metric system. It was as if the U.S. (English, S.A.,E, etc.) measuring system of feet and inches (and all the rest) was under attack by the Metric system used in Europe and/or the “rest” of the world. It was the world of science and some engineering that was promoting this new “cause”.

As a “kid” what did I know. But I did get the impression that the USA was not going… Continue reading

Resting on an Obsession

I got myself into a binge improving my websites. I have to admit that web publishing and doing it well has become a personal obsession as big as working in my shop on “hardware” projects.

I suspect that creative work is never finished as almost any design engineer, graphic artist or programmer will admit they usually come to a stopping point rather than a finish. There is always that one more little tweak that can be added. At least I find that is true for me. What it becomes is a point of diminishing return and a decision is made… Continue reading

CNC Gun Part

A local person here in Frisco asked if I could duplicate this part (the black one). I don’t usually like to take on outside projects as I have enough of my own. This part looked interesting. It is part of a tripod bracket for an expensive, but what the owner called a “toy” gun. Actually is is a very sophisticated collector item.

As can be seen in the photo the bracket had the tab broken off. It is a very nice injection molded aluminum casting but the crystallization left it vulnerable to breaking where it did.

I… Continue reading

Halloween Thought

I have discovered I might have all that I need to die happily in my machine shop. Well, almost. It’s that “almost” that will keep me alive in the long run. Just one more tool then I will die happy. It may be the “just one more tool” that keeps me alive forever. What do vampires know about immortality? HA! All that awful yucky blood and stuff…

It’s bad enough when I nick my finger.  I have a cute little scar on the back of my left hand middle finger where earlier this year I let a 10,000… Continue reading

Do You Need The Balls?

There is a common conception in the amateur machinist world that ball or roller bearings are always the preferred selection to bushing or solid surface bearings. That is not always the case. Machine engineers, of all people, should know it always depends on the application. There are many applications where ball bearings are contra indicated, meaning they should not be used. Some of those reason can be as simple as cost over performance, excessive noise or the possibility of bearing contamination in harsh environments.

The primary benefit of using a ball bearing over other types is the greatly reduced… Continue reading
