  1. Nevertheless. I fear such force is still too much for my frame to bear. Perhaps I'll consider the other suggestion once my other mode of transport bites the dust. Aah, to be a child again and be able to make medieval weaponry without (too many) side-wards glances. Speaking of which. The patang is finally finished. To be honest, it is much too heavy and balanced too far towards the front for my tastes, but my colleague loves it. He says it makes him feel like home, and I don't think I can get a better compliment than that. That really warmed my heart.
  2. After a jump from the 4th floor I doubt my boyish figure would still be maintained. I'd venture I'd be as compressed as the spring. And all that compressed mass would have to go somewhere. I built an onager for the traditional water fight between year 10 and year 13 students once. Not quite the scale of a trebuchet, but fun nonetheless.
  3. And now I've just learnt that there are more than one sort of pyrite. And to think that geology was my strongest subject at uni... My brain must've been working in the background on what galena is, as I just got a mental notification telling me galena is lead ore. Sure is pretty though. Not a bad idea on the bar stools. My brain mainly goes towards catapults. I thought I could make a pogo stick, but seems you have to be about 500 pounds for that to work too, and at that weight I don't think having both feet off the ground simultaneously is recommended. The yellow springs were new one
  4. Picked up some coil spring from the scrapyard. These two, plus their respective twins. Any suggestions to what I can make of them? Also did some more work on the patang. Approaching finished now. Really not a fan of working with big blades I've figured out...
  5. That is odd, but at the same time it makes sense. Different approaches for the same result. I didn't expect that in geology though. Just finished up my bike chain axe. Here is the final result:
  6. Now now. I don't mind learning a bit of geochemistry. Pyrite isn't deposited by water like other silicate based minerals is it? That's gotta be some of coolest fossils I've ever seen!
  7. That sounds like some great fossil sites Frosty. Didn't even know fossils could be formed by pyrite. That's amazing! I'd love to get my hands on some opalised fossils, but that's just another pipedream I guess. I'd imagine not knowing the trilobite location is a bummer. Trilobites are certainly among my favourite fossils. How's this for a project by the way? Bike chain and rasp tomahawk. Or my Mad (M)axe if you will.
  8. Makes sense that they're used for railroad ties. Gumtrees are used for that here too, but then again, that's the most abundant kind of timber here. Very heavy and very gnarly timbers. Unpredictable grain directions I find, so I often get a fair bit of tearout when planing. Haven't worked with blue gum specifically though. Wonder if it's one of the timber species that has high silica content so it wears edges quickly. Fossil hunting is great fun! Surprisingly few places in Queensland you're legally allowed to do it though. I am not a huge fan of the amount of rules and regulations regardin
  9. Marine fossils from what was previously the Eromanga sea. Didn't find anything spectacular, but a couple of fish skulls and bones. And here's a part of a jaw with a tooth still attached. I thought that was really neat! Yep, those eucalypts are certainly tough. Spotted gum has very similar physical properties to hickory, so it makes a great wood for handles. As a bonus it's pretty cheap. Assuming the blue gum was imported as a plantation timber? I imagine the climate in southern California is quite similar to large parts of australia, so would grow pretty well.
  10. The family and I have been outback hunting for fossils. Fun times! Now back to real life (and the shop). Made a handle for my axe. Was going to use spotted gum, but had a piece of silky oak laying around that I thought would look nice though it might not make the best handle. Should've gone with spotted gum as the handle broke on the final fitting...
  11. I like that idea Thomas. A set of shipbuilders tools is high on my wishlist. I would particularly like some traditional Norse tools, but some of the axes they used are much too daunting a project for me yet. Will a wrapped eye adze work well? Interesting info Frosty. I can't do much about my anvils at the moment, but it sounds like I have some hammer faces to dress.
  12. That's exactly it. I would even argue that it's probably better to use just blocks of steel, as that would eliminate any uncertainty around anvil shape, composition and manufacturing process of the anvil and other things I may not be thinking of. But also as you say, the results could only be applied in general ways. A spherical anvil in a vacuum sort of situation, although that would be useful to cut through a lot of the confusion. From your anecdotal data I can gather that anvil hardness is in fact quite important for its efficiency in moving metal. How tall are your anvils? I
  13. Aha. Clearly my Knowledge falls short here. I know nothing of mesquite trees, other than that they're great for smoking pork. Anecdotal evidence can absolutely be useful. I can get a bit too hung up on numbers sometimes. I like the experiment though. Maybe do some analysis of variance and see if there is a significant effect on efficiency from the hardness and mass in combination. That's probably enough for an experiment, but would be interesting to know how much energy is lost if the anvil is not securely mounted. I've seen a lot of youtube videos where the anvil goes for a walk. At leas
  14. I can't imagine you'd walk away from an accident like that and be the same as before. At least not after a long time. Took quite a while after my dad had a couple of accidents before he was the same again too, and one of them was without injury. I'm not sure i would like to moved down by a ten foot cactus either though. I've heard New Mexico can get surprsingly chilly winters. A lot of people will start complaining around here when the mercury drops below 20 degrees celcius. I'm quite happy in shorts and a t-shirt year round. Then again everyone will have to deal with my whinging at summe
  15. Chris: Surface area wise it is only slightly larger and roughly the same shape as my current ALO, so I know (at least some of) the issue that I will face and can dress it appropriately beforehand. Rebound wise... Well it's quite similar to my current sledge hammer head, despite significantly more mass under the hammer, which is why I am considering hardening the face. Or am I wrong in assuming Rebound is a good indication of force transferred to the workpiece? Frosty: That was a lot more injury than I had imagined. I am glad you were able to walk away from that with your life. I'd
