Bending 3/4" plywood into right angles with a 4" bend radius

I have an idea for a stylized plywood coffee table that is all made from a single board of 3/4" Baltic Birch plywood. I've attached a .jpg of a coffee table base-design to this email.  The bends on either side are 4 inch radius bends. Although I have basically no experience bending plywood, I sincerely doubt 3/4 inch plywood is going to bend into right angles at a 4 inch radius. I may be wrong, but if it is possible, I do not know how to do it, and certainly do not have the equipment. I've seen on the internet very flexible sheets of plywood, but wouldn't that just get glued into position and then just collapse once un-molded? I can't believe that I am the only person who wants to do something like this. Any input?

Circuit Bending Workshop at Discovery World (Milwaukee, WI)

Circuit Bending is the art of rewiring and short-circuiting a device to create entirely new sonic possibilities. In a DIY interactive lab environment, learn the basics of electronics by reverse engineering old toys such as the Speak and Spell and other gadgets. Bring an old toy or instrument (check your local thrift store for anything with buttons and a speaker). Then dismantle, adding switches and knobs to create new from the old; this is electronics recycling at its finest. We will be offering two classes in September in October: 1: Intro to Circuit Bending Wednesday | Sept 23 | 6:30 - 9pm $25 Members & MIAD students | $35 Non-Members In this interactive crash course we'll cover the equipment, tools, and techniques needed to start you on your own bending adventure. 2: Circuit Bending Workshop Wednesday | Two-Part Series - Sept 30 & Oct 7 | 6:30-9pm $55 Members & MIAD students | $65 Non-Members In a comprehensive two-part series, participants explore the process of turning toys into noise instruments. We'll cover everything from basic bending and probing techniques to creating noise instruments with knobs, body contacts, photo sensors, and amplifier outputs. CALL (414) 765-8625 FOR RESERVATIONS. Workshops will be held in Discovery World's Electronic Lab, with a maximum class size of 15. What you need to bring: Something to bend- basically anything with buttons and a speaker that runs on batteries (old toys like the Speak and Math and Furby, older Casio keyboards are very bend friendly, guitar effects pedals can be drastically altered), and fresh batteries for your device. Due to the nature of circuit bending there is a high probability of damaging a device beyond repair. If it is valuable to you, don't take it apart! Equipment and beverages (beer for 21+) will be provided, as well as a limited number of toys to bend. Feel free to reply to this post if you have any questions, or e-mail

Wire bending machine or jig for small scale / jewelry findings

So the DIwire looks exciting, but the more I examples I see, I notice it's a bit "low res". I'm wondering if there's a smaller scale solution either electronic or mechanical for jewellery production purposes. I would like to find a way to produce non-standard, custom jewelry findings. Is there a high quality, customisable jig on the market? I want to avoid the inaccuracy of hand bending findings... Also, has anyone come across a concise book on the topic of well designed, innovative or commercial jewelry findings? All I can seem to find is a bunch of ugly "craft" or DIY style books. I'm more interested in having a large collection of finding examples at hand than a book of just 12 DIY walkthroughs. Thanks!

It is not advisable to copy the activities shown in this video.

The Modified Toy Orchestra have a philosophy of performing everything live with a collection of re-purposed children’s toys.., converting abandoned playthings into exotic new musical instruments, and then exploring the latent potential and surplus value inherent in these liberated circuits. Guided by this hidden world they seek to make a form of music devoid of personal narrative or autobiography, instead they ask bigger questions about our relationship with “the next new gadget” the desire for the constant upgrade, and the possibilities for problem solutions hidden from our gaze by perceptual habit. The result of this on going investigation has been called cinematic, dark, joyful and life affirming. It is rare to hear an electronic live performance that has no midi, no sampling, no synthesizers, no laptops, in fact no conventional instruments of any kind. MTO have live dates coming up: 8th September at Birmingham Town Hall 10th September at Manchester Bridgewater Hall Hey, what about the title of the topic? Oh, that's from the band's appearance on the BBC website.  After all, these AA batteries are dangerous... Freeno & Olaf from Modified Toy Orchestra on Vimeo.

Rings of Light: Bending u-channel stock

Hello! I'm trying to make rings of brass with a channel/groove on the inside to fit LED strips into. I want the LEDs lining the inside of the brass rings to illuminate the center, but I want them hidden from view for aesthetic reasons. I'm trying to get 7 different rings, varying in diameter from about 7" to 2'. I can't figure out the best way to do this though. Here are some possibilities I've come up with, and I would love your thoughts on their feasibility, how I might tweak them for better effectiveness, or if you all have other ideas that might work better! 1) Bend U-channel stock in a tube bender. Would this deform the u-channel, though, and can rectangular stock go through a bender? 2) Mill a small trench shallower than a standard u-channel into bar stock, then bend it. See concerns in #1. 3) Somehow mill a channel into bar stock once it's already bent..? 4) Bend hollow tubing into a ring, then use a cutting disc or bit on a dremel to cut an opening on the inside, and snake the LED strip through the tubing. 5) Bend hollow tubing into a ring, then drill out holes at the interval of the LED lights, and snake the LED strip through the tubing. Thanks so much for your thoughts, feedback and help! :)

How to bend plastic optic fiber ?

Hi, I have 0.75, 1 and 1.5mm plastic opic fiber that I am using for my project (which will be the topic of my first instructables ;) ) I need a way to bend the POF in right angle. I don't care if the bending raidus is not very important (spec says max radius is 10 time diameter, 15mm radius is ok for me, and I don't care if I loose a little brightness). I want the POF to stay bend after I have bent it : it must keep the curve I gave it for at least 24 hours. I manage doing something not so bade (but really time consuming) by heating the POF with an hair dryer. I wander if anybody has a better tested idea ? (in the meantime, I'll try putin it in boiling water to see if it kep the shape once cooled). Regards, tReg.

Maker Faire 2009: Peterson Neon

The first year at Maker Faire (2006) the Instructables/Squid Labs booth was just across from Peterson Neon. (She also works near our old Emeryville digs.) It was incredible watching Shawna Peterson bend neon tubing for signs - lots of fire, slow careful movements that carefully bend the glass to match the angles of her templates, and the occasional puff of air to re-expand a bit of tubing that has softened and constricted at a bend point. The sign is worked from the back, so the front looks properly flat and legible.Check out the video Bilal took to see how it's done.

Sample and Loop Frog (Bent toy)

Hey Folks, i ordered this frog at dealextreme. com.Its called a "Digitally Recordable Motion Activated Visitor Welcoming Door Chime Frog". Originally it is a toy that says "Hello" when someone passes by. You can use your own sample, simply by pressing a button to record it to the frog. Nice toy for circuit bending i thought. Here's what i made today. I added loop, pitch control, input and output jack and a button to start the sample manually. Okay it has still a few bugs, but it works. Hope you enjoy the video:

Metal rod stock for furniture (especially loops)

I wanted to make some shelves like this but I have no idea which metal they used or how to bend it. Is there anything strong enough to support even some books that can be bent with pliers? If so, wouldn't it be really hard to get anything good looking? If not, how to bend? I know there are shop brakes, but aren't they only for sheet metal? And, surely you cannot make a 180 turn that small with a shop brake? Also, what gauge/material rodstock to use? Is there some way (even approximate) to relate gauge and material to weight supported?  Many thanks in advance Joe

Equation for accurate bending (kerfing) of plywood

I am planning out my first Instructable. It will be a bent (kerfed) plywood coffee table, There have been a growing number of projects out in the 'makeosphere,' where people are cutting slits or kerfs that go almost completely through a thicker piece of wood, allowing it to be easily bent. I am on a super-tight budget, and cannot afford to ruin my $22 sheet of plywood, so I was hoping that someone might be able to help me with some measurements for cutting the kerf-slits in the plywood. Here is the idea all sketched out. I need help with the measurements that are in bold.  * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *  PROJECT DESCRIPTION:  Materials: 1x | 4 ft. x 2 ft. 3/4 in birch plywood 2x | 3 ft. 5/8 in threaded metal rods 8x | flat washers 4x | standard nuts 4x | "end nuts"  Steps: On the sheet of plywood, measure in X inches and mark X number of cross cut lines, X inches apart. Measure in 2 inches from each end of the board and draw a line. Measure in 2 inches each each side of the board, and draw another line. Drill out a 5/8 inch hold at all 4 of these crossed lines. Thread a standard nut onto each end of the threaded rod and screw it on 1-2 inches roughly, then slip a flat washer over the threaded rod. Bend each end of the board up to create almost 90 degree angles. Insert each end of the threaded rod into the holes, slip a flat washer over the threaded rod and screw on each of the four "end nuts."  Use the standard nuts, and the end nuts to fine tune the bends into 90 degree angles.  Flip the table over, and enjoy.  * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *  Stability is more important to me than curve radius. I don't know if spacing cuts close together for a small curve radius is more or less stable than placing the cuts further apart for a larger radius. I've never done this, but I have seen that there is an equation for this. I haven't been able to find the equation actually expressed, I've just heard that there is one. Does anyone know about this area of woodworking/physics?

The department has placed a containerized data center next to the Ella Morris and Muessel-Ellison Botanical Conservatories and Potawatomi Greenhouse in South Bend, Ind. The waste heat generated by working servers is piped into the greenhouse where it is used to keep succulents and other desert plants warm. reports the university is expected to lower its equipment cooling costs by $100,000. The city will save $70,000 it spends to heat the conservatory. The use of the waste heat is part of the Botanical Society of South Bend’s plan to help make the greenhouses self-sufficient due to budget cuts. ------------------------------ Pretty smart.

For Sale: 30 Jaws musical cards. *UPDATE*

Hey people. I recently got a bunch of Jaws musical cards, and don't have a use for them all. So I thought I'd sell them to you all ;) They play the Jaws music when you open them. And you can rip the card open and get the circuit board and speaker out if it. What can you come up with to do with them? There's one circuit bend that I could find for it, and it's a pitch bend. It sounds pretty cool =) The pitch resistor is R1 on the board. The price is $2 for the first card, and then $1 a card after, plus shipping.  Message me and we can work out the details =) *UPDATE* I just went through all the cards to make sure they work, and had to take some out.. There are now 22 cards for sale. I still have to glitchy ones if you want them. Again, message me and we'll work it out.

knex firing mechanism thingy

I didnt look around much so this may be old news... you can just delete this if it is the idea is that when you pull back and a little up the bolt pops out of the barrel and rests against the front of the chamber, until you push down on the hammer, which puts the bolt back in the barrel again :P if you make it with reds or grays they bend a bit much but it still works the problem is that theres no real way to make it bolt-action

PVC catamaran

So I was thinking of building a catamaran out of two pieces of PVC pipe, either 6 inch or 8 inch. I don't know how long it would have to be to support me or maybe others. Does anyone know of a buoyancy calculator I could use to try to figure this out? Or maybe I could use ABS plastic. This is very easy to heat and bend. This way I could actually shape it a little more, instead of having it just be round and less controllable.

The Future of Invisibility

It is reported that a team of researches at the University of California, Berkeley claim to be on the doorstep of invisibility. Using a special type of metamaterial they are bending electromagnetic waves and negatively refracting visible light. Their ultimate goal is to render entire objects invisible to the naked eye. After reading this, I conducted some invisibility experiments of my own. Based on my initial experiments with invisibility cloaking, I must concede that we are not quite there yet, but are getting close (see image).For more information, read the full news report

I got 217 ft. for range. I measured on google earth. Also, I found that if you do it right, you can use duct tape for the fins. I like the duct tape because it's sturdier, and doesn't bend or deform as easily.
