Getting label glue off glass? - DIY - do it yourself - tribe.net Andy, We live in Phoenix, so completely understand your point about conserving water. For what it's worth, you can reuse any bin of water to soak a bottle, if you're just trying to remove a label. <i>"other products with long chemically sounding names are in fact natural and/or very safe for people and the environment. Is that true? And, an enormous amount of chemical products on the market are not required to go through long-term studies, to find out if they are, indeed, "safe." namaste, alex P.S. And, I understand your point. Biopunk: DIY Scientists Hack the Software of Life (9781617230028): Marcus Wohlsen Top 10 Essential DIY Skills That Aren't as Hard as You Think I think it depends on your definition of "maintenance." I wouldn't hesitate to change my own oil or something like that but I wouldn't dream of replacing a radiator myself. That isn't my idea of "maintenance." That's fixing something. Sorry you are afraid of doing that stuff, but even a complete engine rebuild is easy to do, and no you don't need "special tools" unless you call things beyond a hammer and screwdriver "special" I can do a front end alignment on a car in my driveway with a tape measure and a couple of carpenters squares along with the wrenches most people would have. Also if you do buy the cheap but special tools you can replace your own tires and balance them better than the "laser computerized" balance machine at the tire place. In fact the only expensive special tools I need are a Crane and engine run stand. Danger? This is why I don't take my cars to the dealer for any routine maintenance. Aside from that, dealers are inconvenient.

RUBBER WOOD GEARS (RECYCLED ) - by kiefer This is a true reuse recycle project which will come in handy for some future projects .The gears as you see them are made from two layers of 3/4” plywood glued together and a strip of timing belt from a car engine that was going to the garbage .The timing belt is bonded with GORILLA SUPER GLUE to the plywood hub .These are some pics of how I made them .I rough cut the discs on the band saw then sanded them to size checking the fit by wrapping the belt around the disc and sneaking up to the perfect fit .I cut off a short section of the belt as a alignment piece and clamped at the joint . The application for this according to my grandsons are for wheels on a tractor and on and on.I can see this as a router lift application and a box joint jig indexing device .I would like your thoughts on this and welcome any comments .Have fun with this me and the boys sure have .

Amp Up a Laser Pointer From Wired How-To Wiki Illustration by Lab Partners Your laser pointer could be doing so much more than highlighting PowerPoint slides and blowing your cat's mind. It could be sculpting ice, sparking campfires, or searing one bad mofo on your leather jacket. Here's how to give a standard pointer a power upgrade. This article is a wiki. 1 Disassemble the unit by removing the batteries, opening the housing, and taking out the laser module. 2 Search the circuit board for a variable resistor. 3 To intensify the beam, use a small screwdriver to gently tighten the resistor. 4 Reassemble and aim your potent pointer at safe targets like ice, wood, or plastic.

3D Printers: Make Whatever You Want On most weekends, 14-year-old Riley Lewis and a few of his eighth grade friends gather at his house in Santa Clara, Calif. The group of about five, depending on who’s around, grab some chips and bean dip and repair to the garage, where Riley and his dad have created something of a state-of-the-art manufacturing hub. The boys can pretty much fabricate anything they can dream up on a machine called the RapMan. The kids obsess over what versions of the Linux operating system they run on their laptops and engage in awkward banter. Author Ashlee Vance as rendered by MakerBot Riley and his friends have accepted as a mundane fact that computer designs can be passed among friends, altered at will, and then brought to life by microwave oven-size machines. Like many 3D printers, the Lewises’ RapMan melts plastic (similar to that used in Legos) and then squirts it out of a movable nozzle in a controlled fashion. To a range of industries, 3D printers have become indispensable for doing business.

Alternative rocket casings - APC Forum We just flew three more of the rockets: All were 3 inch cheap winchester hulls filled to the crimp line with composition, and finished up with bentonite plugs. Weights with 4' sticks were all between 50.5g and 52.0g. 1. Rocket was cored about 3/8 into fuel with 11/64 drill bit, was not wrapped with tape to prevent meltdown. When lit liftoff was instantaneous, gone into the clouds. 2. 3. 1&3 were very similar in design and performance. Not sure what else to tell you except they had right around 19g BP in each motor. Now to make them lift something! My video skills suck, all I managed was a bit of the lift off of the first one, then nothing but sounds for the next two.
