table saw blade question

Probably -- check the maximum rpm listed on the blade, then compare to the speed of your table saw. Most likely the table saw is slower than the maximum for the 7 1/4" blade.

The quality of the cut is not going to be as good as you'd get from a decent

Sure. Currently I've been using a 7¼" blade designed for cutting sheet metal to cut plexiglas.

Huh? If the blade is secure on the arbor, all distances from the center spin at the arbor speed.

No, the larger blade will develop a greater rim speed. Otherwise, pulley size would not make any difference in speed on machines. harrym

what brand you using, and what kind of results do you get?

Ok, I concede after thinking about it a little. The fact is that the teeth move at the same RPM as the arbor regardless of diameter which resulted in my post, but the larger the blade, the faster the teeth have to move to accomplish it. Got it.

Here is another that makes you think(at least it did for me). Your squirrel hunting in the woods and one sees you before you see it. It takes refuge behind a large tree so you can't see it. As you move around the tree facing it, the squirrel moves accordingly to stay completely opposite and hidden from you. You eventually circle the tree but of course never see it. Did you go around the squirrel? I say that you do, but the question has become a source of debate among many.

Not really. The very center doesn't move at all.

If the squirrel continues to face you at all times, You do not go around the squirrel. You go around the location that the squirrel is at. Until you are Have gone around all sides of the squirrel, you have not gone around the squirrel. Had you truly gone around the squirrel and there was no tree to block your view, you would have been able to see his back side. To go around an object, you have to be expose yourself to all its sides.

Actually the very center does move. Not in a circle but turns on its axis. If the center did not move, the blade would not move either.

Let's say that the tree was a glass cylinder.

For me to go around the squrrel, I would have to see his left side, his back, his right side and his belly.

If he goes around the glass cylinder as I did, I would never see those sides.

Works for me.

I'm afraid on this one, we disagree. Let's assume that Pluto and Earth rotate around the Sun at the same speed. I know, based on the original question, that makes Pluto moving like hell, anyway - lets further assume that the starting point puts Earth and Pluto on opposite sides of the Sun. I belive the Pluto goes around Earth as well as the Sun even though it never sees us, with your line of thought, it does not - correct?

Another example going back to the saw blade. Put a dot with a marker very close to the arbor but still on the blade. The other dot goes on the other side of the arbor but clear out toward the teeth. Your viewpoint is that the outside dot does not go around the inside dot. I think that it does.

Re-reading this, you'd think I'd have something more constructive to do today, but my shop material hasn't been delivered and it's just too hot out today in Iowa.

So, if there were no tree and you did not move but the squirrel did a pirouette, then your would have gone around the squirrel? Oh, you have to move? Well, if moving is required, then in relation to what?

(Do you have to flash the squirrel, to "expose yourself to all its sides"?)

OTOH, does a geosynchronous satellite "go around" the Earth?

BTW, a propos the saw blade speed questions: At the equator, Earth travels at approx 1000 MPH, while the geo satellites must travel at approx 7K MPH to keep up. So, maybe these sats do not go around the earth. Yet, their positions are often described in terms of their orbits. So, what, if anything, are they "orbiting"?

As with many things, it's all a matter of definitions. (Ask Bill Clinton.) What matters is the purpose of a conversation and that there are certain agreed-upon terms -- if there is a common interest in resolving an issue. For example, will we use English or French or Farsi or Thai?

If I want to say that "A going around B means this ...", then it can mean that. Or not.

Where in Iowa are you? I am in Des Moines.

No. Pluto and Earth both rotate or circle the sun but Pluto does not circles the earth. It Circles the earths orbit which is an entirely different thing.

No, the outer dot goes around the inner dots path or orbit not the inner dot. Since both dots rotate in an exact relationship to each other neither rotates the other. The orientation of both dots is always exactly the same to each other. In order for one dot to circle the other, it has to be exposed on all sides of the other dot at some point.

Ok, I respect the opinion, but have one small wrench to throw in as long as we're not doing anything more constructive. If the Earth rotates on it's axis faster than does Pluto, then Pluto would in fact go around the Earth by your defintion because all sides of Earth would be exposed to Pluto before it completes it's outer orbit - right? The mere fact that the Sun sits between us is simply an obaqe object obstructiong the view. My last post on the subject, you get the last word. I just wanted to spur a little imagination this morning. On to woodworking again.

No, the squirel simply truned in a circle and you stood still. For YOU to circle the "squirel", and not simply the location that the squirel is at you have to move around all sides of the squirel.

If you are refering to a satelite that remains in the same position above the earth such as one that a dish antenna gets it signal from 24 hours a day, NO, the satelite does not go around the earth. It never sees the other side of the earth. It simply goes in circles along the earths orbit but never circles the earth itself.

They obit the earths path but not the earth. To make that easier to visualize, imagine a circle that goes around the sun that represents the Earths path. Now leaving that visual circle in place but removing the Earth altogether, what is the satelite circling?. The circle that represents the Earths path. If they truely orbited the "Earth", contact with the satelite from any one specific receiver or transmitter would be lost at some point in the orbit.

Yes and or the wrong words used to describe an event and or situation.
