Rotten Cookies posted:About where I'm at now. (taken before inlays) That looks loving awesome! What color is the body going to be, or are you going with some sort of natural finish that shows off the grain? If you're going with a solid color, maybe you could add an accent color/stripe at the bottom rather than recutting the body? Like, a blue body with a sky blue accent stripe along the bottom, with a white paisley. If not that, then maybe consider adjusting the location and/or shape of the paisley control cover slightly? A burst finish would solve the problem itself. That's a really cool shape guitar you penned, well balanced but unique, and I'd hate to see it change this late in the build.

M_Gargantua posted:Electric Pocket Rocket. FireStorm has the right idea. Glue together the frame in popsicle sticks (6 thick? maybe 12 thick for the rear trailing arm), then wet the finished frame in epoxy, wrap it in carbon fiber tape, then wet the fiber. Carbon fiber is expensive, but for a project like that you'd only need 1-2 yards of the stuff. Look at what people are doing with lost foam carbon fiber methods and recumbent bikes; a wood cored frame wrapped in CF is going to be similar in strength. While 10' of 3" CF tape is $60, 30' of 3" fiberglass tape is only $10.... http://malricsworld.blogspot.com/2008/12/29-december-2008-friend-of-mine-gilles.html  Click here for the full 1600x1200 image.

ant mouth posted:If you have any questions or ideas as to ways to go faster or handling, shoot em my way! My dad built recumbent bikes via trial and error similar to how you guys are building gravity bikes. Some student used one of his bike designs to test his rotational stability software (or something equally fancy-sounding). The bike had two stability peaks, the first around 32mph that looked like a standard deviation curve, and then a second peak at 62mph (it was a short wheelbase bike, something like 36" from hub to hub on 20" wheels). I'm not sure if this was an error in his software or if this is common, but I'd be curious what your average speeds were and see if you couldn't tailor the bike for better stability in your ideal speed range. Also is there any correlation between gravity bikes and soap box derby cars? There's a rebel league of gravity cars out in SF from what I've heard.

I honestly have no idea what criteria they used. I think the student was just sharing the results with my dad. That data (and the equations used) are locked away on a decade old hard drive in a garage somewhere, and I was 16 at the time when he told me about it. If I had to guess, they were based on wheelbase length, center of gravity, gross weight and wheel diameter... but you probably already knew that  Have you done any tests in the Cascades? I grew up near Tacoma and my dad would spend hours pouring over contour maps (this was in the early 90's, before things like google maps existed) trying to find the longest, steepest continuous downhill highway stretches in the state. I remember a couple of 6-14 mile 4-6% grade roads where we'd hit 47mph (speedo verified) on 10 speeds road bikes. From what I've briefly read, it sounds like Maryhill Loops Rd is quite a bit safer than the damp state highways we were riding on, particularly at the speeds you're hitting.

ant mouth posted:Getting our average speed is tough. As for instrumentation we've currently gone through a few speedometers due to crashing and haven't bought a new one. It is also difficult because it depends on the course were running. The higher the grade and fewer turns means we can hit speeds of 90+. Courses like Maryhill with 17 banked turns we're probably between 35-60 mph. I would love to know what variables your father modified based on the input he got. Ok, well I finally ran across the physics calcs some student did on the max stability of the bike based on rake of fork, center of gravity etc. They don't make much sense to me, but maybe they can help you. http://nearlydeaf.com/files/bikestability/Rocket_Hedstrom.htm http://nearlydeaf.com/files/bikestability/SWB_Hedstrom_noforkoffset.htm

Corla Plankun posted:Use a transformer to get it down to a lower AC voltage, and then rectify it to about 9V DV and use a linear regulator to provide 5 regulated volts of DC. It's really easy. You've already done the part that is a pain in the rear end. Since the generator is already DC, wouldn't it be easier to just use a 12v DC car charger? Rectifiers tend to be hot and heavy IIRC. (and not in a good way) If you had disc brakes on your bike with an even drill hole pattern, you might be able to mount some sort of crude gearing system to it to drive the generator, rather than putting what looks like a big friction brake on the tire.

The problem is that being older, this has an actual wood veneer, but it's started to chip off on the edge there. I can't even think of where I would buy wood veneer, or how to repair these chips. Any ideas?

Are you thinking of doing it grandfather clock-style? I don't think you could get more than five minutes of power out of it, unless you used some custom tempered steel gearing and upped the weight by about 200 lbs. You might be able to modify a grandfather clock to get 20 seconds of light out of it. Grandfather clocks generally have two 20lb weights in them. edit: if you know the weight and distance, you should be able to figure out the theoretical maximum amount of power you could derive from the system. For example a 200lb (90kg) weight falling 5 ft (1.5m) should yield about 4.5w continuous (for 5 minutes in a perfect system), or ~22w of power total. I think. It's been over a decade since I took physics so I might be off by a factor of 10. A really powerful handheld LED flashlight from walmart pulls about 2w I think.

There was the hull of a concrete sailboat floating in the harbor by my house for about 10 years, it's pretty sturdy stuff. If you run in to a rock, just sail it up on a tidal flat, lay it over and spackle some concrete + iron mesh over the crack, paint it, and keep on going. It's not as durable as an all-steel hull if you get washed up on the rocks during a storm, but more than a few concrete boats have circumnavigated. There's a 420 ft concrete boat that's been turned in to a sort of park in Galveston Bay (near Houston), it's been there since 1922. Her sister ships got towed up near Alaska where they're still floating (Barely) and have been tied up for use as a breakwater for a logging port. Some sort of WWI "conserve steel for tanks and guns" spruce goose style experiment involving concrete. http://www.crystalbeach.com/selma.htm

I picked up a parts bike for my bamboo bike earlier this week, then the day before I went to go harvest bamboo, it rained more than it had in the previous three months combined >:( Supposedly you need to wait at least a week (closer to a month) after the last rain to minimize the existing water content and chances it will split/crack when you cure it. Those are great resources, especially the instructible of the asian guy who made the bamboo fixie. He has a link to a really smart, simple jig which can just be bolted together. In the comments of that, someone links to a serviceable version made from 2x4"s From what I can tell, the two hardest parts are 1) getting that nice, smooth "calfree" style joint and 2) getting enough clearance for a 36x700c tire. The calfree style joint just looks like they sanded down the hemp fiber composite smooth and then added an additional "clear coat"... As for the rear wheel clearance issue, that seems a little scary, unless you find some particularly curved bamboo specimens. What size wheel are you using and how are your clearances? Did you have any problems fitting the wheel/bamboo? It seems that you can get some extra clearance by canting your seat tube at a pretty drastic angle, but then you need an oversize hemp blob at the top to distribute the additional leverage that creates on the frame. Also I guess you can make the bottom bracket lower than the centerline of the wheel, but that might look a little wonky, plus you run in to pedal strike issues. edit: this is the stuff calfree uses, supposedly: http://www.entropyresins.com/products/super-sap-clr How many ounces of epoxy did you end up using for your bicycle project?

Well by clearance, I mean the width of the tire, not the diameter. Looking at my bottom bracket, I'm not sure there's much room to widen the chainstays.... although I was thinking about 1"+ chainstays. The way my metal chainstays are setup, they are "crimped" where the wheel is to allow additional clearance close to the bottom bracket. We all know what happens when you "crimp" bamboo... This is my donor bike, it's very similar to yours, a 27 1/4" bike: link Nubile Hillock posted:Yellow denotes areas I want to wrap with strips of fiberglass cloth (like wrapping your handelbars, but for structural integrity...) over on the bamboobike wordpress blog, he has some pictures of the brooklyn bamboo bike studio. After tacking the frame back together, they wrap the joints in blocks of pink foam (which, I think is the same as blue foam) and then file them down in to more pleasing shapes, then wrap that in hemp fiber + epoxy. Supposedly it's just as strong, and reduces the total amount of epoxy by 2/3rds or more since it's just a 2-3mm shell of fiber reinforced resin.. in theory that should more evenly distribute the stresses around the shell and away from the joint.

That bamboo bike is coming along great! I can't wait to see how your joints end up. Are you going to use hemp, CF or other? Ropes - there's a huge grove of the stuff that acts as a privacy wall on the Katy Trail between the trail and the mansions on the other side of it just north of Blackburn St. I'm not a huge fan of harvesting things out of parks, but there's at least a quarter mile of bamboo 15-20 feet deep in all sizes, so a few poles won't go missing for a single project.

I used to have to change the posters every week. Our frames did not have a diffuser behind them. You're fine. Movie posters are printed on much thicker paper with high quality (thick) ink though, and that may cause some perceived diffusion effect.

I think you will be disappointed by how much turbulence (camera shake) the tubes perpendicular to flow of water. Cool design, excited to see how it works.
