    Two "handle bar" positions

    Right on, thanks, will do. I've never done hydraulics before. I was concerned about probably one foot longer cables, maybe 9" but the added length, over time, is not a benefit. Hydraulics might be better, I'm happy to learn more about that. I youtube a lot. Thanks for the tips and helping...

    Two "handle bar" positions

    Flat Tire, it may be a metal pipe clamp that secures the seating frame to the seat posts, and 3D printed parts connects/integrates the clamp to the seat mount body. I would use 3D printing more for integration than mission critical load bearing whenever possible. The general idea about 3D...

    Two "handle bar" positions

    And before anyone continues down the, but you are seating up too high for such low pedals to have a comfortable riding position path,,, it's roughly the same design as the infamous long wheelbase design that started the modern recumbent movement back in the 70's represented by the gold rush and...

    Two "handle bar" positions

    I posted that I "might" want both seating positions and thus both handle bar positions IF that can be reasonably done. But how would I replicate the motor and display controls??? Would I need a seperate controller too? Im more than willing to have only one seating and handle bars position is...

    Two "handle bar" positions

    No, it's a tiltable seat, so you can be at any incline. The second set of pedals are yet future possibility. I first want to just figure out how to deal with two different handle bar positions. In other words, how do I deal with two sets of breaks, throttles, displays, controls for the display, etc?

    Two "handle bar" positions

    Degrading will get you,,, where you probably are, not as far as being more productive. The engineer question was to get at why be against 3D printers, not against engineers as a trade, and least of all against you as a personal comment. Please try remain topical and not to get me completely...

    Two "handle bar" positions

    Here's a link to the video demonstrating increased strength by adding carbon fiber infused for 3D printing. Also, if you use mark forged I think they are called, they include a proprietary form of laying down a continuous thread of carbon fiber to add in the layer plane strength greatly. I...

    Two "handle bar" positions

    I saw serious tests showing top class strength in both the layer plane "and" 90 degrees against that plane, "both" planes of testing surpassed most other entries and demonstrated a strength and stiffness increase, not just stiffness like you claim.. Maybe if you don't use a proper printer you...

    Two "handle bar" positions

    Yes,,,,,,,, I want to steer from the recumbent seat shown. ... ............. and optionally the upright seat too. Hence the two handle bar positions question for how to control it all from both positions. That question is not, do I need more than one handle bars. Although that is part of it...

    Two "handle bar" positions

    I'm seeking suggestions for how to accomplish two handle bar positions. I'm hoping to have two handle bars and seating positions available. I guess I could try for two seperate handle bars with twice as many cables as before, to control all the controls on the first handle bars, including...

    Im back w/tandem conversion into recumbent ebike project!

    Thanks neptronix, much appreciated. Here's a graphic peak at the project.

    Im back w/tandem conversion into recumbent ebike project!

    I have been gone for a long time but I am happy to say that I am back as I am finally doing my long awaited recumbent ebike build! It must have been, IDK, 5-10 years going back when I was here last. This place brings back good memories and the buzz of fresh ideas over cool bit of awesome...

    Fat Tire tadpole trike axles & turnbuckles

    I want to use 20"x4" fat tires on my yet future trike I'm hoping to start building next spring, but I'm having problems finalizing parts for the front wheels. The question is, I'm seeking a very solid axle and turnbuckle (or kingpin), like on ATV's or small dune buggies. I can source the sway...

    Tandem bike conversion to 1-seat tri-mode Recumbent

    Here's a mockup of my present bike. I might do this as its much cheaper than buying a tandem to modify, and better turning radius and easier to store.

    Tandem bike conversion to 1-seat tri-mode Recumbent

    Here's the latest mock up,,, I like this one the best so far. I prefer more of a medium wheelbase for control and turning radius, but the medium long wheel base is next best thing. ;) Front=3" from smaller tire, 1" from recumbent position improvement = 4" front. Rear=1 inch closer to frame, plus...

    Tandem bike conversion to 1-seat tri-mode Recumbent

    Here's an updated design. I like the idea of two pedal positions. The top one for smooth airflow road cruising, the bottom for stop and go, high traffic, tricky and uphill conditions. Ergonomic bonus, easier to ride longer using two pedal positions. Notice I shortened the wheelbase for improved...

    Here's another rendition. I like the design and shape of the body-n-wheels better. Enjoy.

    Tandem bike conversion to 1-seat tri-mode Recumbent

    I am creative inventive type. I have arthritis throughout my body but mostly effects my back. So a recumbent ride would help out greatly. I want to build an all wheel tilting recumbent trike, but I don't have the workshop laboratory to be able to accomplish it yet, so I am simplifying the...

    Enclosed recumbent design

    Thanks everyone and nice find Docnjoj. I found out they have a Facebook site too. https://www.facebook.com/Drymer Also sk8norcal deserves special credit for having arguably the coolest website collection of leaning vehicles. You really should check out the site if you haven't already...

    Can one shift a (sine) wave up or down like on osciloscope?

    To simplify matter, lets remove the alternator from the equation for a moment. Lets say I have a standard AC only welder and a DC only welder. Lets say we want to add some DC to AC for negative balance to be able to weld aluminum. Couldn't you just add the DC lead to the AC torch (and add DC...

    Can one shift a (sine) wave up or down like on osciloscope?

    PunxOr I am also afraid I might not succeed,, but sometimes fear should give way to creative venture. Pretty hard to advance if you just stick with the safe bet. However I surely don't have enough money to sink into a failed project. Others have done similar to what I propose before but not...

    Enclosed recumbent design

    Still early in design stage, not near future project, but spend enough time making scads of designs, so here's one of my best so far. I am curious about suggestions for material selection for such a design. I think those are 20" tires, about 55" tall (near car seat height) yet very aerodynamic...

    Can one shift a (sine) wave up or down like on osciloscope?

    Why do I want to build a DIY welder out of an alternator/generator? 1) I am getting ready to build couple projects where welding is needed. I have constant sometimes severe back pain so I am pursuing a DIY recumbent bike or all wheel leaning trike. I need a general capability welder (on a...

    Can one shift a (sine) wave up or down like on osciloscope?

    Friendly1uk posts another good idea to make it happen. Time swapping the same electrode with AC then DC, and then just vary the amount of time each type of power dwells compared to the other. I figure high power and high frequency are not easily combined and swapped like that. But, if it can...
