a PS (in case some high schooler wanted to try this) Trying to measure the depth of the impact depression directly probably too difficult/expensive. But what this depends on is the modulus of elasticity of the material and that you can find other (easier) ways to measure. In other words, your project just needs to defend that the substitution of test method is valid. So ...... a) Impact device to measure resistance to denting (how hard can the wood be hit and leave no dent). Move stock along with gradually increasing impacts and note at which point dents begin to appear. b) Modulus of elasticity measured by beam deflection or something similar. |

Go for it, try to have fun, and buy enough stock to build two units; the first one might not work out correctly. *My* rantings are about collecting enough information for wider recommendations on woods, especially those wood types available outside of Asia. If the burden and cost are low, I certainly agree with just trying it (and the advice on building two units). My focus prevented me from this, potently best, recommendation of "just do it". Lots of materials will result in a playable board and I'm sure you'll greatly enjoy your homemade board! Though I would add that the Janka hardness of the wood might affect what material your stones are made of, whether you risk breaking slate and shell, or glass, or just go with plastic (or wood). |
