![]() Where effectiveness under the hammer is concerned both anvils are more effective on steel tripods than on wood blocks and I did use stacked lumber for a short time before getting a wooden block for the Sorderfors. They (my anvils) don't move if the stand doesn't, Hammers and tongs are right THERE and they've taken the ring out of a Soderfors and a Trenton, both known for a deafening ring. My hammer and tong racks wedge between rim and anvil foot to secure it. The interface between my anvil and stand is a flange up angle iron rim the same size as the anvil foot. I don't know what the angle of the legs is on my stands but the more vertical the more rigid, the more rigid the better. ![]() Marc 1 and I prefer a steel tripod though I haven't seen an improvement with a steel plate to bolt the anvil to, nor heard a lessening of ring by filling the legs with sand let alone sand and oil. Placed in contact with an anvil concrete pulverizes without improving anvil performance. Concrete is strong in compression because it doesn't compress measurably and has virtually no rebound. resonance being the waves reflecting from opposite sides till they eventually stop. the anvil while true isn't very accurate. ![]() What you're referring to as the "energy of the hammer blow" compressing, etc. High compression strength is NOT impact strength. It's an intuitive thought but a concrete stand is actually worse than wood. The thoughts have been discussed a number of times here. The energy of the hammer blow then goes more into moving the work. With everything bolted down, bouncing, flexing and lateral movement are significantly reduced. The base also improves once it is attached to the ground. An anvil which is firmly attached to a solid base has different characteristics than one which is simply resting on the base. How can we recover that energy?Īttachment is the crux of the matter here. That energy was not used to deform the work. The shock of the hammer deforms the anvil slightly, which then continues to deform at its resonant frequency until the energy is used up in heat. An anvil will ring because it is free to do so. If I weld a 200 lb anvil to a 500 lb block of steel, instead of just resting it on top, will that change the characteristics of the anvil? If so, then at what point do they essentially become one mass? My point of reference on this question is whether all the pieces resonate at the same frequency. That's an interesting thought, and one worthy of discussion. Two different materials with an interface do not become one as much as one would like them to. For reference, the approximate weight of 1 cubic yard of concrete is only 4024 pounds Any type anvil stand is a compromise to a direct connection to bedrock via the pier. If you can not find bedrock, then pour a massive concrete base to substitute for the bedrock. Anything less than going into bedrock is a compromise (the stand resting on different types of dirt or material above the bedrock). What is the most solid way to connect the two? One way would be to drive a large pier into SOLID bed rock, and then attach the anvil via a solid connection to that pier. Will it work the same? (This disregards the size differences of the anvil face, hardie holes, etc)Īnother way to say this is the anvil of YOUR choice (the one you use) is connected to the ground (earth) via the anvil stand (for convince and height). With the 500 pound anvil resting directly on the ground, we can construct a 450 pound stand for the 50 pound anvil and get the same mass in contact with the ground. If the stand weight adds to the mass of the anvil, then why do we have different weight anvils? For discussion let us take a 50 pound anvil and a 500 pound anvil. To get perfect contact you can use a 3 point contact system, but that raises the stand off the floor except in those 3 locations, and makes the stand to floor connection with an air gap under a lot of the stand. Unless the floor is flat and in perfect contact with the stand it can wobble a bit. Put a pad in the mix and it fills the air gap but does not improve the design. Will there be, or develop in time, an air gap between the wood and the anvil (anvil now supported on the concrete) or an air gap between the concrete and the anvil (anvil now supported on the wood)? If an air gap develops then the shorter length material has lost its effectiveness. Give some thought to the interface between the anvil and stand.
