« on: May 28, 2016, 02:05:04 PM »

This is one of my all-time favorite bikes

I usually hate yellow stuff, but the stickers/parts/frame always sucked me in...

Sometime around 2004/2005 I got a red shaman from Chris Cotsonas (odyssey), off of bmxboard.

It was the frame that was used in a black-and-white evolver (brake) ad. somebody please post that ad. I've found it in my magazine stack a few times, but never scanned/capped it


sadly, a friend's brother took the bike out and got it stolen one night around 2006, and I STILL stress over that thing. Any bike I see at the dump gets my hopes up.

I never took pictures of the bike itself aside from this one

but here's my bmx-test profile on it from ~2005

Freecoaster is new
Chain is new
Sprocket is brand new

stuff often comes with way too much grease in it.  have you taken the hub apart at all? seen the youtubes of how to do it?  ediot should know what he's talking about here, regarding the stickyness. Or maybe it's something else, I don't know. I've had the hub for a year now(?) and still haven't built it up, but I know that george has mentioned the grease/lube a few times - that you don't need to add any when you install it because it already has more than necessary...

ediot, please post the yellow Standard. I never get sick of seeing that bike

Airbus APWorks unveils 35kg 3D printed electric motorcycle
http://www.3ders.org/articles/20160520-airbus-apworks-unveils-35kg-3d-printed-light-rider-motorcycle-yours-for-50k.html

May 20, 2016

http://www.lightrider.apworks.de/#!en/dkqv3
https://www.youtube.com/watch?v=Fad7zXGR85c

APWorks, a subsidiary of Airbus Group, has built a fully functional 3D printed motorcycle. The vehicle, which has been dubbed the ‘Light Rider’, is made from APWorks’ Scalmalloy material and weighs just 35kg.



Ever since APWorks first announced the creation of Scalmalloy, a high-strength aluminum-magnesium-scandium alloy, the Airbus subsidiary has been keen to show off exactly what the material can do. First came this super-lightweight, 3D printed airplane partition, and now an entire vehicle has been made from the stuff. The Light Rider is, admittedly, smaller than your typical Airbus vehicle, but before the aerospace giant 3D prints half its future airplane fleet, this 3D printed motorcycle, unveiled today in Ottobrunn, Germany, demonstrates just why Airbus and APWorks have so much faith in the potential of Scalmalloy. “With the Light Rider we at APWorks demonstrate our vision of future urban mobility,” said engineer Stefanus Stahl.

Weighing in at just 35kg, the 3D printed Light Rider is around 30% lighter than conventionally manufactured e-bikes, can zoom from zero to 45km/h in just three seconds, and has a top speed of 80km/h. The secret to the impressive bike is its 3D printed frame, which weighs just 6kg, part of the reason for the vehicle’s 60km battery life. Although its appearance might take some getting used to, the topologically optimized structure of the frame is designed to eliminate mass where it is not required. APWorks actually developed a special algorithm, inspired by bionic structures and natural growth processes, to work out where material could be eliminated and where it needed reinforcing. The result is a skeletal, almost organic-looking structure, with not a gram of surplus material in sight.

According to APWorks, the lightweight, optimized, 3D printed frame could not have been produced using any other manufacturing technique: “The complex and branched hollow structure couldn’t have been produced using conventional production technologies such as milling or welding,” explained Joachim Zettler, CEO of APWorks. “Advances in additive layer manufacturing have allowed us to realize the bionic design we envisioned for the motorcycle without having to make any major changes. With these technologies, the limitations facing conventional manufacturing disappear.”

APWorks has worked at the forefront of additive layer manufacturing (ALM) and advanced materials since its launch in 2013. "3D-printing technologies have revolutionized the design and manufacturing process – not only in terms of structure and aesthetics, but also in impressive weight savings on parts and equipment," says the company.

To create the incredible 3D printed frame, APWorks used a selective 3D laser printing system to distribute the Scalmalloy powder in layers just 60 microns thick. By 3D printing these parts, APWorks was able to create unusual shapes and reduce mass, while also reaping the other rewards of a bottom-up manufacturing approach: many of the Light Rider’s 3D printed frame parts are hollow, which allowed the designers to integrate cables, pipes, and screw-on points directly into the motorcycle body.

Scalmalloy, the aluminum-magnesium-scandium alloy used by APWorks to create the Light Rider’s frame, is a corrosion-resistant material which purportedly exhibits titanium-like strength. Designed specifically for additive manufacturing purposes, the material combines strength with a high level of ductility, making it ideal for robotics, aerospace, and automotive 3D printing projects.

APWorks plans to build 50 more Light Riders, available to buy for €50,000 each. A €2,000 deposit is required to join the waiting list.

I got some sort of mongoose from the dump a few weeks ago with big chrome powerbend bars and primo logo grips... psyched.

28.5 X 9" or so, might be a bit taller/shorter, but it's right about 9. I don't know about using them for tricks and stuff, but just wheeling them around they feel really good.

also, why have I not seen anybody else mention mat breaking his old height record, on a 30ft ramp, in 2015?

...I started playing around on Big Ramps again. I rode one in March at the Old School get together at Woodward West in Tehachapi, CA. I was pushing 20 feet comfortably and felt I could go higher than I had before. There were a lot of people around and I knew I needed to do this just for myself to get the focus needed. I had been in the ER many times recently, so I second-guessed myself and walked away to prove I could and to give it more consideration. It kept burning bright, so I decided it’s in me and I had to let it come out.

I’ve been riding a lot but also flying wingsuits, which I think has helped me cross train by harnessing aggressive energy better, become one with it and flow, like the big ramp demands. Painting more has helped sharpen my focus too, plus I’m 43 years old (the holy grail of BMX or so we claim), so I decided I was mentally ready to take on the challenge.

Danny Way talked to me earlier in 2015 about designing a ramp to get more air. He wanted to go so high nobody would want to step to it. So he built this ramp (30 feet tall), kept it a secret and was ready to test it out this past May. At the same time, I had committed to push my limits on these big ramps again too, so the timing was perfect… he invited me out for the test ride.

I went out there and had a private session. I set up some unmanned cameras and filmed the whole session(s), which I’ll show later this year. I was able to break my past record. This sketchy pic was one I shot of a camera screen from one of Danny’s friends who captured it at my first session. It’s definitely not print quality but I liked how the style was so much like the original air I did on my original Big Air ramp in 1991, but higher.

It’s now been 25 years since I made a bike I could trust my life with going bigger than ever before. Let my life be an example to never give up, follow your heart and do what you want no matter how many times you’ve been knocked down and people tell you you’re crazy or it’s impossible. Keep getting up and keep your dreams alive. Keep your game true to your heart and push your life’s passions and skills, no matter how ridiculous they may seem to others. Always following your dreams to wherever they lead….

Love Life and make your dreams happen, no matter what! This is what 25 years of Hoffman Bikes is about to me. I was 18 when I set my first high air record. I had to build a bike I could trust my life with to achieve this. Now I’m 43 and I still make a bike that can back my dreams no matter how big they go….

Go Anywhere, Do Anything! Hoffman Bikes 25 years Strong!

Peace, Love, BMX – Let’s have fun in 2016!

point being that A LOT more people have smartphones than 3d printers.  It'd be more accessible, more people would be doing stuff with it/making advancements.  Easier for more people to get artsy/experimental...  progression/expansion.  Not creating anything new, just making it more accessible/cheaper for others to do it.

I'm cheap as fuck and I want this to be as easy as possible...

I kind of struggle to see how a phone screen can fling out enough light to cure resin quickly and accurately enough, when our little sla machine uses some sort of death laser and still takes a while... Cool if it does work though.

I haven't seen it/that video until now.

Paused at ~12 seconds in to log in/post this.

the music, the voiceover, the actors... seems fake, like an snl sketch


just finished it.  I can get deep into conspiracy/surveillance stuff about how it might definitely eventually be possible for phones to do this -  apple patents for camera lenses/sensors between pixels, laser stuff, iris/retina/finger tracking stuff, etc - but I'm pretty sure this is just another 'microwave your phone to charge the battery instantly' type of thing, getting people to cover their phones in resin.  I also don't believe that those guys are italian...

I'd be psyched if it's real, especially for the potential metal casting stuff, but it feels like a setup for a shitty old joke...

NAHBS 2016: 3D printing hits its stride
http://cyclingtips.com/2016/03/nahbs-2016-3d-printing-hits-its-stride/

March 18, 2016

Once solely the stuff of dreams, prototypes, and engineering experiments, metal 3D printing is finally starting to trickle into bicycles that people can actually buy. Moots and Reynolds both previewed 3D-printed dropouts at this year’s North American Handmade Bicycle Show, while two builders — Bastion Cycles and Métier Vélo — have based their entire frame designs around the technology. What once was the stuff of science-fiction movies is quickly becoming reality, and an entire new world of possibilities has opened.
Fully custom geometry from Bastion Cycles and Métier Vélo

It still isn’t practical to build complete frames on a 3D printer. The printers are too small, for one, and there’s no advantage to using the technology for simple tubular structures that are better served by more conventional manufacturing methods. However, that hasn’t stopped Bastion Cycles and Métier Vélo from using 3D printing’s advantages where they make the most sense: at the joints.

Both companies are taking a similar approach, using 3D-printed 6/4 titanium lugs bonded to pre-formed carbon fibre tubes. The benefits are the same from either outfit: the possibility of fully custom geometry with no additional tooling costs, along with the ability to create structures that otherwise wouldn’t be possible (or practical) through forging, casting, or machining.

“Performance-wise, [3D printing] enables us to really manipulate not only the external shape of the titanium. to get stiffness and strength into it, but on the inside, we’re able to manipulate the structure with things like lattice work and ribs and variable wall thicknesses. to put the strength where we need it,” Bastion Cycles co-founder and managing director Ben Schultz told CyclingTips. “This means we can achieve the weight and stiffness and strength of a carbon bike, but using titanium, which, when we use it selectively at the nodes, actually creates a better ride comfort than if it were carbon fibre.”

Indeed, Bastion Cycles’ single initial model — a disc-brake equipped road bike — could easily pass for a moulded carbon composite frame, had the company chosen to cover the structure in paint. The printed titanium lugs are artfully sculpted with character lines rarely seen in metal frames, and with a surface finish that’s remarkably smooth for a printed part. Those lugs are then bonded to filament-wound carbon fibre tubes.

Métier Vélo, on the other hand, still highlights the lugs’ 3D-printed origins, but with shapes more reminiscent of classic steel, with scalloped and pointed sleeves as well as the company’s stylised fleur-de-lis logo integrated right into the surface of each lug. While the adjoining tubes are still carbon fibre, Métier Vélo founder Jamie White has opted for roll-wrapped tubes from Rock West Composites, located nearby in South Jordan, Utah.

“[3D printing] is total design freedom,” White told CyclingTips. “This kind of approach is ideal for small custom builders because it costs the same to do one bike as ten bikes. There’s no real economy of scale.”

“One thing I’m offering is free repair or replacement,” he added. “If anything happens to the frame, I just want people to bring them back. [Repairs are] pretty easy to do. If there’s a dinged carbon tube, I can just replace the tube and if there’s any titanium damage, I can just reprint the parts. It’s a nice way to build a bike from a repair and durability perspective.”

White takes a consciously conservative approach to his frame design, using lugs that he considers “overbuilt” by supplier GPI Prototype & Manufacturing Services, with wall thicknesses ranging from 0.75mm to 1.5mm depending on location. Likewise, whereas many carbon fibre frames have paper-thin tubes you can literally squeeze between your fingers, the tubes White sources from Rock West measure a stout 1.3mm. Even the bond surface areas are three to four times what White considers to be necessary for the applied loads.

“There’s about 400-600g of titanium, and the rest is carbon,” he said. “The software package I use has some finite element analysis in it. All of the lugs are way overbuilt. That’s one of the things I consulted with GPI about. The modelling I’ve done shows that the carbon tubes will break before the bonds or lugs give out.”

White has some destructive testing planned for later this year that will likely allow him to pare his frames down a bit, but even then, he doesn’t plan on ever catering to weight weenies.

“Because I use more more titanium and carbon than is minimally necessary, my frames probably won’t ever be much below 1,100g or so,” he said. “There’s about 400-600g of titanium, and the rest is carbon. My goal is to make tough, durable, and repairable frames that perform well. If someone wants a 550g climbing frame, I am not their builder.”

Based in Melbourne, Australia, Bastion Cycles is being far more aggressive in what it can produce, using lugs with walls as thin as 0.5mm while also incorporating ribs, cross-members, and lattice-like internal structures that it says adds measurable strength and stiffness. Claimed frame weights are impressively light, right around 1kg, a substantial 200g lighter than Métier Vélo’s. However, Bastion is more comfortable flirting a little closer with the edge of reliability thanks to a full battery of in-house ASTM durability testing, a distinct rarity amongst the hand-built crowd.

Bastion Cycles is also highlighting the capabilities of its flexible manufacturing techniques with an extremely clever online configuration tool that lets potential buyers customise their frame’s geometry and build kit as well as its ride quality, stiffness, and projected tire clearances — all with an instant estimate of the final frame and complete bike weights. The online tool also generates a nifty graphic that visually compares the current selection with other well-known industry benchmarks.

In either case, riding on the cutting edge of bicycle frame manufacturing technology won’t come cheap. Métier Vélo is currently selling its frames for a whopping US$8,500 with a Chris King bottom bracket and headset; Bastion Cycles’ frame is a comparative bargain at AU$7,500 including a Whisky No.9 carbon fibre fork, headset, and bottom bracket.

3D-printed dropouts from Moots and Reynolds

Moots and Reynolds also showed off 3D-printed bits at NAHBS, and while neither project is quite as ambitious as what Bastion or Métier Vélo showed off, you’re far more likely to see one of these out in the wild. Both are being printed by i2M in Birmingham, UK.

Moots is using the technology for flat-mount, thru-axle rear dropouts on its latest disc brake-equipped road, gravel, and cyclocross frames. According to company president Butch Boucher, the 3D-printed dropouts allow for internal structures that wouldn’t otherwise be possible using more conventional manufacturing techniques, and should make for more consistent final products.

“The thing that we were really challenged by, looking at flat mount, was that it would be asymmetric in terms of where the welding goes on the chainstay,” said Moots president Butch Boucher. “All titanium expands and contracts when you weld it, and it also contracts more than it expands, so it’s going to move if you’re asymmetrically doing something. So here we have an opportunity to symmetrically weld — we can maintain alignment through the whole process so much better.”

“The consistency of the product is our biggest goal,” Boucher continued. “We make quite a few frames a year relative to everyone [at NAHBS]. When you’re doing onesies, you can kind of manipulate things and deal with them one at a time, [but] we need to have a consistent product from start to finish. It’s like a chef in a big, good restaurant. He’s got a crew on the line that he knows is going to create a consistent product. Part of that is what the recipe is, part of it is the ingredients, and part of it is the skill set of his crew. To have it be the same every time is the biggest challenge we face.”

Similarly, Reynolds is also using 3D metal printing to produce flat mount-compatible rear dropouts, although in this case they’ll be offered in both 6/4 titanium and steel — in both thru-axle and quick-release wheel interfaces — and they will be available to any frame builder who is interested in using them. According to Reynolds, its new 3D-printed dropouts will offer strength comparable a 2D-forged part along with drop-in compatibility with existing frame building fixtures.

Reynolds hopes to have them available to builders as soon as April or May, at a cost of around US$180-200 per pair.

Moots isn’t offering its dropouts to other companies, but Boucher says that while they’re not exactly inexpensive to make, they likely won’t add much — if any — cost to end consumers.

“If it’s not net zero, it may cost us just a little bit more. It’s not cheap but it saves us multiple steps.”

The Lounge / Altoona, PA trails?

« on: March 15, 2016, 04:47:08 AM »

a long time ago somebody here posted pictures of some trails in the woods near the lowes in altoona.

I lived there when the lowes was first opened. The grand opening was like a fair - spotlights and chainsaw carvers and stuff.
Then I saw the trails in person in 2002/2004 when I was back visiting, then saw them posted here a few years later.

There's some sort of Park designation/symbol right by them on google maps that says "Altoona Trails" but I don't know if it's just walking paths now or what...   

Do they still exist?
