You do get used to judging sizes. Sensing if things are correct. I've done this sort of curiosity for decades. You don't get paid for it - but it's something that you see and go .... Hummmmm.

On a spring guide. I needed to turn a segment to .530" on a length of delrin.

Made the first judged cut. Measure to verify. Of course - you want to be a few thousandths over on critical steel parts. Take a final finish cut. This part would be fine within a tolerance of +/- 10 thou. Guess my mind just said ... That'll be about right.



Do this sort of thing all the time. Haha.

When I used to occasionally make a couple of pocket knives alike - I'd accidently pick up parts out of sequence on the bench. Like a blade from knife one and lock bar from knife two. And, they'd fit and just almoooost be correct. But - just not as smooth. I'd track the problem and discover the error. Both just fit by hand - should never be close. As I say - you don't get paid for it. Often it's a nuscience. Ha.

Anyway. Finish this spring guide and I'll take a couple shots with this Outrider 50 Action.

The 'ol calibrated eyeball in action, eh?

Works for feel too, if you have enough experience. The crew chiefs / mechanics that work on helicopters get really good at judging just by feel how worn out some particular parts are, for example. By feeling the "slop" in the ball joint end of a pitch-change link they can figure if one needs replacing, or if it's still "good to go". One guy I used to work with could tell within about a half of a thousandth of an inch how worn one was just by the feel of it. If it was close to the limit, they'd put a dial indicator on it to check and he'd be right on the money every time.

That's experience at work. Precision eyeball is what we call it at our shop . That's good Karma finally going in your direction Gary . The stars are aligning , and all is well in Gary's world . Just think if you could whip up a couple on your 3D printer .... Would ya ?

Hi Kurt,

Yes, I'm feeling much relieved. The mind is starting to calm some. I realize I'm way behind. A man is responsible for his decisions. Not for fate. Fate and decisions "could" work together. Could cancel out negative karma. Very seldom does. Usually they exaggerate the error. But; you can wear it down, if you just keep at it. Haha. I saw Old Man Fate limping out the driveway earlier today. Didn't even look back.

I can never get closer than .005 by eye.

Lon

I can't even see .005 unless the other .5 is there!
