PVC Unistruts??

Hi, I need to make 10 garden carts. They have to be light weight, capable of handling 400-600 lbs, have a 4' x 5' adjustable height platform, and on casters. I was thinking about making the supporting structure out of a high tensile strength poly vinyl rectangular or square tubing. Anyone know of a source??? Thanks

Caustic Soda vs Soda Ash, using to clean a bast (stem) fiber. Do they have the same affect on the strength of the fiber? Answered

I'm working on a project to clean (dissolve) bark off of some fiber that adheres to the inside of the bark. I've used caustic soda (sodium hydroxide) successfully but it weakens the fiber. Soda ash (sodium carbonate) also works and seems to have less affect on strength but I'm wondering, chemically, if there's any real difference. I don't have access to any gear to accurately measure the real tensile strength. Thanks for your help. Shanti Mama Kathmandu Nepal

k'nex pump-action with a dropdown removeable mag?

I am trying to biuld a k'nex, pump-action, dropdown magisine, with stock and sight. I have everything running smothley apart from the magisine & i need help! The things i am looking for is,... # The magisine has to be removable. #The magisine runs smothley without cataching or jaming. #The magisine has a good amount of shots. #It must include a clip to go on the gun for it to slide and clip into. #And it must have a tensile to push the shots into the chamber. If somone manages to do this and follow all of the things obove I will post an instructable about my gun. With all credit to your name for the magisine. (I tryed to add pictures but my camera was playing up).

Adhesive/fill material needed

I need an adhesive or fill material with some special properties. It should be a moderately viscous liquid that sets up into something very flexible, jellylike would be ideal. It should be applicable in very small quantities. It should flow before curing and be self leveling unlike silicone adhesive. Tensile strength is relatively unimportant. It should not adhere to two part tin based casting silicone. An analogy that comes to mind is E6000 adhesive but it's viscosity is a bit too low and it sets up way too hard. UV cured resin like Loon UV Knot Sense (great stuff that I learned about here) comes close and has the right viscosity also but also cures too hard. If you know of anything, I've got a project on hold until I find something and would greatly appreciate advice.

Sitar bridge mod (for floating-tailpiece guitars) idea

The characteristic sound of a sitar is created by a bridge that gently rolls away from the strings; this creates a buzzing timbre which quickly depletes higher overtones in the string's vibration (I could draw some diagrams if anyone's interested). This type of bridge is something I'd like to make as a removable modification for a guitar. My guitar has a "floating tailpiece" as I believe it's called, in which the strings pass beyond the bridge to the tailpiece. The segment of the strings below the bridge have no part in tone generation, and so could have an object attached to them (a piece of wood wedged between the strings, perhaps) without affecting the guitar's tone. If some object (the "clamp") were attached to the strings immediately below the bridge, another object (the "sitar bridge") could be affixed to it some minuscule distance from the vibrating portion of the strings. The sitar bridge would not make contact with the strings at rest, and so would not be a node of vibration (and not affect the strings' pitch), but when the strings are played, their vibrations would make them rattle against the sitar bridge - much like the bridge of an actual sitar. So how about it? I think it'd be an interesting and relatively simple mod that could be made to be removable and not destructive at all to the actual guitar. I unfortunately have no idea how to refine the concept any further than what's written, so I leave it up to any willing DIY-ers. It all makes sense in my head, but I may have accidentally left out some important particulars of this kind of mod, so please ask any questions you have. Because this mod relies on the strings below the bridge in a floating tailpiece guitar, I don't think it would work on most solid-bodied guitars, but if anyone can come up with a similar mod for the more common bridge type, be my guest. Also remember that the "clamp" below the bridge cannot rely on the tensile strength of the strings, as not only are they not terribly strong, their tension needs to remain intact so that the guitar can be played in tune.

Light Sensitive Chicken Coop Door

Hi, I recently started keeping my own chickens and have really enjoyed the whole experience. The chickens were all really friendly and provided hours of amusement. Until a few weeks ago I had 4 of our feather friends in a nice Coop. That was fine until one night, for the first time ever, we forgot to close the door to the coop. Unfortunatley the fantastic Mr Fox must have been casing the joint for some time and siezed his opportunity. Three of the chickens were nowhere to be seen, the fourth lay dead under our rhubarb. So why am I telling you all this sad tale? well, I have stumbled accross a solution to this ever happening again. On Ebay I can purchase a 'VSB Automatic door opener', but it'll cost about £100. This is also not ideal as by current door for the coop opens horizontally not vertically, which would mean replacing the door. I'm also concerned that the light unit will be underneath a roof with this design, so it may close prematurely, leaving the chickens trapped in the yard. I'd like to have a go at making my own automatic closer for the coop, possibly solar powered (with a rechargeable battery) that could be mounted to the side of the coop. I don't mind adapting the door to make a vertical opener, if that makes the project easier. The specs for the bought units are: Compact geared motor with steel gears ensuring extremely long life. Battery life now 3 to 4 years with an HS sliding gate or 2 years with a 1.5-kg sliding gate featuring a 50-cm lift. Dorkeeper operates considerably more quietly now. Thanks to 40-kg breaking strength, the rope can hardly break any more. Electronic shutdown of motor within one second when the sliding gate is blocked.Once the blockage is removed, the sliding gate will be opened within three minutes. The strain on the batteries is virtually negligible. Tensile force: 200 g to to 3 kg, with idler UR on the sliding gate (pulley) 6 kg. Does anyone have an ideas how to make something suitable/similar? I have included photo's of the coop showin the current method for closing (Metal foding arm)

Amazon's very expensive cable, and the comments for it.

Http:// I was flipping around on Kotaku, and came across a page talking about the MASSIVE rip-offs involving HDMI cables. I read the article and found this link in the comments. This is a $9,000 audio cable from Amazon. I went down to the comments (mostly to see if some idiot bought this), and found some interesting comments. And by interesting, I mean I fell out of my chair laughing.  -------------------------------------------------- Some comments: " We live underground. We speak with our hands. We wear the earplugs all our lives. PLEASE! You must listen! We cannot maintain the link for long... I will type as fast as I can. DO NOT USE THE CABLES! We were fools, fools to develop such a thing! Sound was never meant to be this clear, this pure, this... accurate. For a few short days, we marveled. Then the... whispers... began. Were they Aramaic? Hyperborean? Some even more ancient tongue, first spoken by elder races under the red light of dying suns far from here? We do not know, but somehow, slowly... we began to UNDERSTAND. No, no, please! I don't want to remember! YOU WILL NOT MAKE ME REMEMBER! I saw brave men claw their own eyes out... oh, god, the screaming... the mobs of feral children feasting on corpses, the shadows MOVING, the fires burning in the air! The CHANTING! WHY CAN'T I FORGET THE WORDS??? We live underground. We speak with our hands. We wear the earplugs all our lives. Do not use the cables!" - By Whisper ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- "If there is one cable I would whole-heartedly trust to my Chimera-hunting needs, this would be the cable. No other cable has the tensile strength to properly and efficiently garrote a lycanthrope, asphyxiate an Esquilax or even gag a mermaid. Last week, using my trusty AudioQuest K2 (retrofitted with lead weights, bright orange latex paint and a generous coating of crushed glass stolen from the window of an abandoned church at midnight), I managed to snuff 3 golden unicorns in swift succession!  Pros: Quickly tears through scales, fur, bone, and adamantium with ease  Coils and uncoils from hip holster (optional) quickly and quietly  For a product fabricated from 1,000 Onyx Dragon fetuses, the price is unbelievably reasonable!  Cons: Shipping from the R'lyeh took far too long  Doesn't come in 10' lengths (which would be perfect for hydra, cerberii and other multi-headed creatures)  After every use, I can feel 6 ounces of my soul slipping from my core into the ether. But this may be due to the fact that I prefer to work without gloves. YMMV.  Overall, I would recommend that any hunter buy one, nay, two, of these immediately, and experience the difference that upgrading to the K2 will make in your next quest!" - By Valannin "Pantheon Outcast"
