I don't know what to use. Should I use tips that explode or tips to spear. The torpedo I am currently making is made for ballistic tips but which should I use?

Hello to everyone who took the time to read this update/list. So I have not forgotten about my promise to upload the Solidworks files and cutting plans. However that will be taking a backseat to finals until summer break. I will however go ahead and list off the items finished, in progress, on hold, or currently only in Solidworks form. Finished -6in Axe: 3lb head on an oak clad 1/4in steel flat bar about 20in long total -3in Tomahawk/Axe: 1.25lb head on a para cord wrapped 1/4in steel flat bar about 20in long total -27in BoneSplitter: 3.2lb aluminium reinforced steel construction. -18in BoneCracker: 2lb aluminium reinforced steel construction. -18in All steel BoneCracker: 3.5lb steel reinforced steel construction. More square handle and better center of balance than previous version In progress -10in Bearded Axe: 3.25lb head. To be mounted on oak clad 1/4in steel flat bar handles 18in, and 30in long. -10in blade Pugio: Model made of mild steel for practice and training. Needs to have bevels, and fullers ground plus handle and guard mounted. -8in blade Pugio: Model made of mild steel for practice and training. Needs to have concave edges, bevels, and fullers ground plus and guard mounted. On hold -14in Blade tester: Simple test bed modeled after BoneSplitter to test viability of various band saw blades(Metal and Wood cutting) for use as cutting edge for mild steel blade carriers. On hold due to the band saw blades being too hard to drill through. Only existing as Solidworks files --27in Revised BoneSplitter: 4.5lb Aluminium reinforced steel construction. Better center of mass and more square handle than MY previous version. --37in blade Bastard sword: Aluminium reinforced steel construction. Should be very close in terms of center of balance and stiffness when compared to its hardened steel companions. --20in blade Stacked steel Gladius: Twin riveted steel support plates with detoothed metal cutting bands saw blade used for striking edges. --blade Hispaniensis Gladius: Single piece of metal for the blade. --blade Cinquedea: Single piece of metal for blade. Multi fuller blade. --8in blade Pugio curved: Same as other 8in Pugio except for the convex curved dagger tip --14in blade Spear from Fullmetal Alchemist: May upload the variant of this in which the "wings" are separate pieces of metal. --3.25in square Warhammer: 8.5lb head Assembled from 13 1/4in steel plates pinned together. Front is covered in 3/8in spikes poking through a steel striking face to prevent separation of the plates. Back end is a 4in spike. --5.25 square Warhammer: 16.25lb head Assembled from 21 1/4in steel plates pinned together. Front is covered in 3/8in spikes poking through a steel striking face to prevent separation of the plates. Back end is a 4in spike. --Straight edged War Axe: 7lb head Inspired by Ironclad Industries' Riftclaw. Made from 7 1/4in steel plates pinned together. I am aware that the riveted and pinned construction of these items makes them inherently less durable and less corrosion resistant than single piece construction. However I am a college student who is working with mostly scraps and whatever has to be purchased. Since mild steel thick enough to carve the Warhammers or War Axe is not common scrap material around the college's machine shop the only way to economically create them is to use stacked plate construction. As for the BoneSplitter, BoneCracker, and Bastard sword the stacked plate construction is used to both reduce the weight of the item and stiffen it at the same time.

I was making a bamboo hunting spear (Which I will make an instructable on soon), and when I found the heart of the stick, it was gross! The inside was covered in this snot-like substance that smelled horrendous, and the sponge type thing that is usually inside bamboo was practically gone! Does anyone know what could have caused this?

I have seen videos on Youtube & Instructables about make a Spear/Arrow head stronger, i was wodering if this is due to tempering (Ex. Steel Heating, cooling rapidly for stronger atomic bond) or due to some other method of strengthing I do not know about ( I only know the Steel method due to mass History/Science channel fanatical-ness) Plase help me uderstand this.

Hi Folks. My lovely better half just came home from a walk with her mum & presented me with a very old Spear & Jackson saw that belonged to her late father. It has suffered a bit over the years, it has some corrosion & some light pitting on the blade but nothing I shouldn't be able to sort out; being an inquisitive guy I'm intrigued by the wording embossed on the handle "Wartime handles and screws" . I'd love to find out more about this old saw, perhaps when it may have been made & why it has this wording on the handle, I have quite a few tools made during & shortly after WW2 which I inherited from my father but have never seen this before. Any info folks? Update. I stripped the saw & started the first stages of bringing it back to some of its former glory this evening. Rubbing it down with wet & dry & a sanding block revealed the etching under the corrosion, I'm afraid the picture may not show it up too well but along with all the usual Spear & Jackson stuff it showed the model & number of the saw, its a Spearior model 88 which according to info from the web has been in production in one shape or another since around 1920. I've come across a couple of methods online but before I start does anyone have any suggestions for enhancing the etching?

May I ask what qualifications you posess? When you say you "know the way of all the weapons and how to make them in under 10 mins" you are lying. Yes they can be made badly form odd found materials throughout the home, but to make for examble a ninja-to bokken or yari spear at best will take days.

So I've recently being trying to replicate Prince Nuada's spear from Hellboy II, and it seems that the hardest bit will be the middle bit with all its fancy engravings and whatnot (The section between the blade and the handle). Im unsure what I should use and how exactly to engrave it all. I would really rather not resort to painting it on, but if I engrave it into wood I'm worried that after a couple of coats of primer and paint I will loose all the detail. I want it to be fairly strong so I may have to resin over the engravings if I dremel the design out of wood, which would make it even less visible. What do you think would be the best way to engrave it all out?

Just a few days ago I made a portable K'nex cannon. I was just wondering If I should make it be my first instructable. Here's more info: Range: Average Accuracy: Difficult Size: Medium Extras: Loading stick doubles as a small spear, end of barrel has points, and Includes ammo carriers. Should I post it?

Anyone have any clue what this tool was used for or what it is called? It was found in the dirt on a farm. I will attempt to describe as best as I can hoping that this will help after you see the pictures. It looks like the main piece is like a large needle with an eye at the one end and a point at the other. Then there is a curved hook sideways to the main piece (see the shadow on my leg). The hole/open portion in the middle appears to be some sort of clamp. When you press on the tab piece that is closer to the eye, the hole opens up, releases the pressure on whatever may be inside the hole.

I would love to see a good spear for fishing and a sheild I have not seen many sheilds. If my message body is bad don't judge me i don't really know what to say this is my first time posting something like this and excuse my bad grammar please. Also I'm new here thats why I have not posted any instructables yet.

I'm reasonably certain that I didn't dream this up, but if I did I am sorry. No, not really because somebody should make a coffee brand called that. Anyway apparently there was back in the DDR a coffee brand called 'JavaFix'(spelling uncertain) Which is either a mistranslated or made up name or it was actually called that in which case it's awesome and I have to know where to get a tin or two. (or at least a high resolution image.) Yes I did google it and no I didn't find any appropriate links. (Presumably Britney Spears owns the whole coffee industry with something weird called a "latte" or a 'frappuccino' I assume it is some type of hard drug made of amphetamines ground toddlers and the anguished cries of dying orphans...)

What do you all think of this practice ? Coming soon to a pc near you....government trojans.A government Trojan is spyware installed on a computer or network by a law enforcement agency for the purpose of capturing information relevant to a criminal investigation. Depending on the program, government Trojan horses may intercept email or VoIP traffic, scan hard drives for relevant digital media or even record conversations and videoconferences. As this type of software captures data and then sends it back to a central server for processing and analysis without a user's knowledge, it is generally classified as a back door Trojan horse virus. Governments have approached implementing Trojan horses in different ways. Swiss government agencies have been reported to be working with Internet service providers (ISPs) to record speech on an infected PC's microphone, as opposed to of intercepting encrypted voice packets. German agencies have sought authority to plant Trojan horses on the hard drives of suspected criminals using email that would install keyloggers, record webcams and microphones and scan infected hard drives for for documents, diagrams and photography. These email messages would be tailored to each unique target, similar to the method used in spear phishing attacks.More about Government Trojans.

We're used to thinking about the cost per unit of energy (e.g. $/gallon of gasoline) with the implicit assumption that cost is a rough indicator of what is required to obtain that energy. The Oil Drum has a nice piece on Energy Return on Investment (EROI) and the implications of using low EROI energy sources. To dive right in, it's instructive to think about the EROI of domestic oil production as a function of time:100:1 in 193030:1 in 197011-18:1 in 2000EROI on the Web part 2 of 5, (Provisional Results Summary, Imported Oil, Natural Gas)Energy return on investment, sometimes called EROI and sometimes called EROEI, is thought by many, including myself, to be a critical issue for determining the past, present and future status of human society. It is usually considered in terms of energy return on energy investment, but it can also be considered in terms of energy return on monetary investment. While much of human progress has been attributed, rightfully, to technology, much of that technology has been a means of using more energy for human ends. This is true for fire, knife blades and spear points (energy concentrating devices), the development of agriculture and the increase in its productivity and, essentially all aspects of the industrial revolution.EROI is simply the energy delivered by an energy-obtaining activity compared to the energy required to get it. If the numerator and denominator are expressed in the same units (barrels per barrel, MegaJoules per MegaJoule) the result is a dimensionless ratio, i.e. 100:1 or 10:1). Obviously a higher ratio implies a more desirable fuel than a lower one, other things being equal (which is rarely the case). The concept is extremely simple in theory but often very difficult in execution, mostly because society generally maintains its records in monetary rather than energy terms. Another problem is that the U.S. Government has not supported such studies in a consistent fashion and it is my perception that the quality of some energy records as are kept by e.g. the U.S. Departments of Energy and of Commerce appear to be deteriorating in recent years. Thus deriving the energy cost of getting energy (or most other things) is generally somewhat, and oftentimes exceedingly, difficult. A second problem is that the usual measure of the quantity of a fuel, its heat value, often does not give a full assessment of that fuel's ability to do economic or other work. Most simply electricity and thermal heat from e.g. coal or oil have a great difference in their ability to do work, such as we are willing to trade three or four heat units of coal or oil in a thermal plant for one thermal unit of higher quality electricity. Thus if the input and output fuels are of different quality then it is often thought desirable to weight in some way the inputs and the outputs. A third problem is that it is important to consider boundaries: how large should we draw the boundaries of the energy analysis for the inputs? We will consider these issues in far more detail in later publications but there are many reasons why it is important to make summaries of EROI available at this time even though many uncertainties exist in the numbers that we present here, and indeed with any numbers that might be possible to generate.via jforbess

MARKET STREET PROTOTYPING FESTIVAL OPEN CALL Autodesk Keystone Project Call Opens: July 11, 2014 Call Closes: September 2, 2014 Shortlist Interviews: September 17-19, 2014 Proposal Selection: October 1, 2014 CALL SUMMARY: The San Francisco Planning Department has partnered with Yerba Buena Center for the Arts (YBCA) to produce the Market Street Prototyping Festival: an innovative, hands-on, publicly sourced approach to creating the next chapter of San Francisco’s public life. The Market Street Prototyping Festival builds upon a five-year, multi-agency effort for a Better Market Street to re-establish San Francisco’s civic spine as a place to stop and spend time, meet friends, people watch, or just stroll and experience the scenery. As a formal piece of the planning process, the Prototyping Festival will commission and exhibit up to 50 design projects that aim to improve lives by improving public spaces. Each of the selected prototype projects will be installed on Market Street for the full duration of the three-day festival, which will take place in April 9-11, 2015. Matched with one of five Festival Districts on Market, selected teams will work directly with community members to shape the direction of their designs. The call for applications for those 50 projects is currently open and will close on September 2nd, 2014. More information on that process can be found on the Market Street Prototyping Festival website. Market Street will be broken out into 5 districts along the corridor: Civic Center, Central Market, Retail, Financial, Embarcadero. Each district, or "Block," will be represented by a Block Captain. Each Captain will mentor 10 selected prototyping teams and will be responsible for developing their own Keystone Project that will serve as the primary focal point for each district. As the Block Captain for the Embarcadero district, Autodesk is seeking proposals from engineers, industrial designers, architects, artists, and interactive designers for a large-scale Keystone Project to serve as a physical, visual and social anchor for the Embarcadero section of the festival. While there is no official theme for the festival itself, the Autodesk Keystone Project should relate to the ethos “Inspire, Design, Create.” Additionally, it should connect to the character of the Pier 9 Workshop where artists, designers and fabricators are empowered to test the limits of existing technology, both digital and mechanical. Special consideration may be given to projects that incorporate the following themes related to place-making and the unique social and spatial conditions of the Embarcadero district: • site specificity: social, cultural, geographic, and civic histories • connecting digital and physical realms • daring experimentation/playful prototyping • edge condition: city + waterfront • wayfinding and transportation networks LOCATION: Over the course of the festival, the city anticipates foot traffic of over 300,000 visitors. The Keystone Project may be installed anywhere within the festival’s Embarcadero district, which starts at the intersection of Market and Spear Street, extending to the traffic island at Embarcadero and Market, possibly including Jimmy Herman Plaza. See the map on the Market Street Prototyping Festival website for more details and note that Autodesks main San Francisco office is located at 1 Market. PRECEDENTS: The following projects are examples of what the application review committee is looking for in terms of scale, tone and available resources. These samples are meant to serve purely as a reference and are not works that will be featured at the festival. - Sukkah City, Various, New York - 21 Balançoires (21 Swings), Daily tous les jours, Montreal - Light Drift, J. Meejin Yoon, Philadelphia (Note: Projects for the 2014 Urban Prototyping festival cannot be installed in the bay.) - Digital Empathy, Julianne Swartz, New York LOGISTICS, EXPECTATIONS, AND SUPPORT: The selected project and team will be fully supported by the Pier 9 Workshop! We look forward to having you join our creative community of Artists in Residence, other Creative Projects Teams, and the folks who make Instructables.com go. We provide ample opportunities to collaborate with other designers and makers, to receive training on any of the machines in our workshop, gain software support for all Autodesk products (including free software licenses), and call upon the expertise of our fantastic Shop Staff. We can supply a modest office workspace and 24-hour access to the workshop. All basic workshop supplies will be covered, including hardware, sheet goods, finishes, and prototyping materials. Additional funding will be provided at an amount to be determined. We expect to support an innovative and inspiring project that reflects the use of our world-class facilities, at a scale similar to the precedents listed. For more information on the amenities available at Pier 9, see the Pier 9 Overview and Machine Catalog Instructables. Your project will also receive support from Autodesk’s public relations team, marketing team, video and photo documentation team, software specialists, and workshop fabrication specialists. There will be an expectation that you will work collaboratively with all of these groups to share the progress and product of your work. Finally, we have an Advisory Committee representing expertise in areas of landscape architecture, sustainability, and digital fabrication that can be called upon for consultation and critical feedback at particular points in the project timeline. The selected artist or team will be expected to formally share their progress throughout the development and fabrication process with the creative community at Pier 9 and beyond. This includes: • posting Instructables related to the making of the project • 2 presentations to the Advisory Committee for feedback • 1 lunchtime presentation to the full Pier 9 community, near project completion TIMELINE: July 11, 2014 —RFP Release July 22, 2014 —12pm lunchtime RFP Info Session at Pier 9 September 2, 2014 —Proposals Due September 17-19, 2014 — Semifinalist interviews October 1, 2014 —Keystone project announced October - December, 2014 — periodic consultations with members of Advisory Board Early December, 2014 — Presentation and critique with the Advisory Board Early February, 2015 — Follow-up presentation and critique with the Advisory Board 2 weeks before festival —Dress rehearsal (deadline for full assembly and functionality) April 9-11, 2015 —Installation and three-day festival presentation APPLICATION REQUIREMENTS: - 1 page statement regarding the concept, siting, and fabrication strategy for your proposal - Up to 5 photos/videos of mock-ups or prior work - CV including exhibition history (if applicable) - Proposed budget outline (Please include direct costs, materials, artist fees, contractors, and any additional project contributors or contractors) - Draft project calendar including proposed dates for prototyping workflow, workshop production time, completion time(s), and out-of-town dates (if applicable) - List of anticipated machines and materials needed ABOUT PIER 9: Autodesk’s Pier 9 workshop is a world-class fabrication facility on the San Francisco Bay. The Artist in Residence (AiR) program gives artists, designers and Instructables authors a chance to work with us in our lab and workshops to explore, create, and document innovative projects with our tools and resources and share them with the DIY community. AiRs are invited to come for a period of several weeks to several months, during which they will work on projects that are shared across the Autodesk Studio Communities. The primary goals of the residency program are to produce top-level inspirational content and to connect innovative and creative individuals with our unique set of tools and resources. Questions and inquiries are encouraged. We look forward to learning more about your work. Please submit applications with all materials compiled in a .zip file titled with your project name to: P9PublicPrograms@Autodesk.com.
