I like the longer conical horn as it tapers to a finer point than my Old World German. Not as good as my bigger anvil but it will work just fine. The anvil returned the hammer well enough. While my hammer control has improved since I did the review of the Russian Anvil, this anvil showed no marking of any kind after my first project. I plan to chain it down to reduce the ring. The TFS anvil is just sitting on top of the stand. The anvil rang more than my 170 pounder but my big anvil is chained down to the stand. Last of all, I fired the forge and made my first tool for this anvil: a bench dog type hold down. The manufacturer says the anvil is hardened to Rc52 and the rebound and file bite suggests this is about right. I put it on the wooden stand and repeated the test with the same results. After repeated testing, I would say that this anvil averaged about 80%-85% rebound over the entire face. I put the anvil on my garage floor and did the ball bearing test. My question is: how much longer would it take to grind these castings with some workmanship and pride? The casting gates were roughly ground off and evidence of their presence remains. The parting line was ground but not cleanly. The anvil appears to have been cast on its side. It is only an aesthetic issue and the blemish will cause no problems. Evidence of grinding to remove superficial defects was found on the horn near the cutting table. The horn and face were ground to an acceptable finish, not further grinding is necessary except for rounding the edges. The anvil body was painted flat black and it had no rust on it. The anvil came wrapped in cellophane, no crate. Not cheap but not that much more than an eBay anvil of questionable heritage for which premiums are usually paid. The anvil retails for $550 and county taxes added another $32. It took only a week to get the anvil to Houston and I paid no shipping charges. I ordered the anvil from a local Farrier Supply who said they bought from Delta Horseshoe. My shop anvil is a 170# Old World German Pattern that has served me very well for the past 5 years. After about a year of fruitless searching, I purchased a new Texas Farrier Supply 100# Blacksmith anvil. anvil to use for demos and to take to meetings of the Houston Area Blacksmith Association. See the pattern? The force drops off with the square of the distance.I have been looking for a 100-lb. Ten times the distance, one-hundredth the force. If you triple your separation, the force drops to one-ninth. If you double your distance from the planet, the force is one-fourth. On the other hand, the farther you are from the center of the planet, the weaker the pull between the planet and your body. If the planet you are standing on is twice as massive, gravity also pulls on you twice as hard. If you double your mass, gravity pulls on you twice as hard. First, it depends on your mass and the mass of the planet you are standing on. ![]() This force of gravity depends on a few things. The Relationship Between Gravity and Mass and DistanceĪs stated above, your weight is a measure of the pull of gravity between you and the body you are standing on. It still has inertia, and hence mass, yet it has no weight. If you grabbed the anvil and tried to shake it, you would have to push it to get it going and pull it to get it to stop. Are you or the anvil mass-less? Absolutely not. If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. ![]() This force of attraction between you and the Earth (or any other planet) is called your weight. How? All you have to do is stand on a scale! Scales measure the force of attraction between you and the Earth. For everyday-sized objects, this gravitational pull is vanishingly small, but the pull between a very large object, like the Earth, and another object, like you, can be easily measured. The amount of attraction depends on the size of the masses and how far apart they are. Every object in the universe with mass attracts every other object with mass. ![]() Mass is a measure of how much inertia an object displays. This quality or "sluggishness" of matter is its inertia. Once you've got it moving, it wants to stay moving. If the stone is at rest, it wants to remain at rest. If you shake an object like a stone in your hand, you would notice that it takes a push to get it moving, and another push to stop it again. An object with mass has a quality called inertia. The mass of a body is a measure of how much matter it contains. We often use the terms "mass" and "weight" interchangeably in our daily speech, but to an astronomer or a physicist they are completely different things. ![]() Before we get into the subject of gravity and how it acts, it's important to understand the difference between weight and mass. ![]()
