If by "a couple of inches" you mean "five or six feet" I'll go with that. I've had small pieces similar to what the OP described vibrate into the back of the blade and cross the shop. Type of blade, type of wood, blade height, phase of the moon -- there are a lot of factors that can allow it to happen. *Normally* you only get a couple inches. *Occasionally* something a lot more exciting happens. That is why it is a good idea to keep out of the line of fire.
You are describing your experiences, Leon, which are a valid data point, but they do not define what is possible, only what *you* have observed.

True, but that would tend to be thrown up face-ward, not horizontally belly-ward, wouldn't it?

Oh...or is _that_ what Leon was going on so about--that it isn't necessarily gutting time? I had no thought whatsoever about anything other than it's possible for an offcut to get hurled--I figured "how high" was sorta' immaterial if it's heading your direction and you're a fair target.
Anyways, as noted earlier, my lesson was taught in mid-forehead--unlike my grandfather who had a faint outline of a hoofprint from a mule that clocked him when he was a teenager to the day he passed, I can't see a mark any more but I can still feel the place it struck if I need a "don't do that" reminder. :)

LOL, no, I still stand behind the fact that circumstances have to be just right for a loose piece of scrap to be thrown with any force regardless of blade positioning. That all goes out the window if there is something providing resistance when the scrap hits the blade. Several years ago there was the talk about wearing a glove when using a TS. The fear was that the blade would catch the glove and pull your hand in. I conducted an experiment and pushed a canvas/leather glove in to the spinning blade, the clove cut just like wood, no shredding and no pulling into the blade, just a slot/kerf spot was the result. I don't think gloves should be used, if your glove hits the blade you may be startled and actually push you hand into the blade as a reflex. And yes I have flipped small pieces of scrap in to the back of the blade and back tooth area with no constant resistance. The pieces simply flipped back out most often still landing on the TS table top. Typically the scrap is going to go right back in the direction it came from.

I guess this kinda got off track as the OP had no problems until he caused the problem. ;~)

Sure. And I wouldn't have had a problem if I had not been cutting wood. Caused my own problem, too. Really Leon, I think you are missing this one.

What I am saying is that you should let scraps lay, don't move them while the blade is spinning. The scraps are 99.9% more likely to simply push off of the blade and go no where so to speak unless you physically push them into the blade with resistance using something like a push stick.

Oh... I understand now. Yeah, it depends. If I can clearly get the piece safely, and there is some danger of it getting caught, I will get it. If I can not clearly get it safely, and there is some danger of it getting caught I tighten my sphincter while I reach for the off switch.
You are right. I certainly don't want to push it into the blade!

And typically a cut started will be successfully completed. Otherwise, I don't think I would bother.

Depends on the blade height. I always work (for through cuts) with my blade as high as possible. If an offcut hits it, it lifts a little but doesn't fly forwards. Working with the blade lowered "for safety" will put offcuts in contact with a portion of blade that's travelling forwards instead, thus throwing them at you.

I have never witnessed any pieces being thrown anywhere unless it was trapped, in many years of wood working.

Lesson learned huh Gordon? ;~) Apparently you trapped the scrap between the blade and the push stick. Better to leave the scraps and let the next scrap push through the pile or turn the saw off. "Unless trapped" between a fixed object, push stick, fence, jig, and the blade, the scraps will simply push away from the blade.
