concave footpads



  • @chabis Thanks for all the great feedback man! Your input and suggestions are spot on. The reason I created flat cave was definitely the sensor. I felt like keeping it as flat as possible while creating some slight heel toe ramp would be a good starting point. I'm definitely interested in parabolic and W. Im also still learning and limited in my 3D modeling ability but want to explore these shapes. The flat cave was fairly easy to draw in sketchup/trimbal. I have pro version so am able to export .dxf files to my partworks program. I'm happy to share either files. Also happy to work with you on your custom prototype and send it your way. I have no idea how much shipping is an issue from N.C. to Switzerland. What did you think of the second design with the elliptical side cut/body kit and increased footpad width? I'm really excited about seeing it underfoot. Hopefully have something together by end of the week. Look forward to seeing where this goes @chabis!



  • Would be cool if @njcustom would carbon fiber the body kit add ons. I could shape them out of EPS foam and send a set to him to bring to life! I think they will look pimp in wood also with many different species/finishes available. Also thought about rhyno liner over EPS. If the body kit ends up working I think it is also a great way to protect a new board from ever being scratched.

    WOW looks like we almost have a complete body kit for the OW now. It will be Interesting to see where this goes.



  • @ashewheeler you are very welcome! happy to bring in my ideas, combine them with yours and create something new!! my brother used to be a carpenter. he's quite some experience with CNC milling. left his old job though and is now a design engineer. so i asked him to have a look at the pictures of your prototype and the 3D model you made and uploaded to this forum. you're using a CNC to mill the pads right? he offered me to draw exact plans and export the file(s) you need so you can mill them using your CNC. you'd just have to tell me what file format(s) you need. and you would have to send me the measurements marked with the letters A, B, C, D and the radius R marked on the sketch below. of course i can try and get them on my own by measuring with a tape, but since you already made a prototype you probably know all the measurements (in mm or inches.. preferably in mm) already. am i right? you in?

    he'd do a version of a W shaped concave deck. we'll figure out the shipping stuff once the plans are drawn and sent to you :-) but i don't think they are too high. @njcustom sends his fenders internationally and we (non us citizens) only have to pay 10 bucks extra.

    regarding the second design: i really do think it is worth exploring. and seeing that njcustom already liked your post i assume he would be interested in a possible collaboration should you, me or the both of us decide to work on this project. i also think it is not too hard to realise once we have come up with a more or less final version of a concave footpad. because looking at your models and considering the plans that could be drawn, it would just be a matter of adjusting. i reckon you would have to mill additional holes for additional screws that hold together the rails you propose. the only thing i do think could be a challenge are the holes for the charger and the power button.. what do you think?
    what i also noticed though that this way, the footpad would only be significantly wider towards the wheel.. correct? that may not be enough since most of us do stand in duck stance on the deck. however, i might change my opinion if i have a prototype of a concave deck (i got rather big feet) or see a photograph with a "big" foot placed on it. may the concave deck's already enough? nice to see the willingness to collaborate!



  • @chabis sorry for radio silence. Shit has been crazy here. Got those measurements for you. A=228.5mm or 9", B=241mm or 9.5", R=19mm or 3/4". Don't worry about allen screw holes yet. I will punch those out by hand after the CNC mills the concave. I'm gonna be working on my deck today. Hopefully have some photos by end of the day. Happy wheeling bro!



  • Wow - cool stuff....love the R&D. One thing I would really like is rounded corders like a skateboard. I know this really cannot be accomplished until OneWheel changes the design in V2 or what not. When I do sharp 180's I typically dig the front corner of the board into the ground. In the long run seems kind of silly to have these square corners. Just my thoughts.



  • @atl1wheelin I think the design thinking for the square tips came from the potential for nosedive. Something more pointed may auger in much easier. The square coped end blocks actually glance off the ground (especially concrete) if you are lucky. That's not to say other shapes couldn't be engineered to be friendly during nosedive. Love your recent park footage surfing the bank!



  • @ashewheeler Thanks bro! Appreciate the WheelLove!



  • This post is deleted!


  • @ashewheeler and anyone else following this thread: this would be the current model. any suggestions/ input regarding the shaping ?

  • @chabis if you (or anyone else) are up for sharing 3D model, will print up and give it a try. I'm guessing grip tape will work fine on regular 3D printer plastic long enough to get a feel.



  • @shaunabe good to know, thanks!

    does anyone know the exact position of the allen screw holes? this way i could include them in the 3D model as well :) would be nice to know.



  • First assembly of elliptical body/concave footpad kit. Sensor swap is complete with mob grip tape. Pads are milled from plywood, body rails from red brandis. The pads and rails are all glued together and quickly dyed black with quick spray paint can lacquer cuz it's 1st proto. Being the first assembly there are some imperfections but glue up is really rigid. The sizing of the parts isn't exactly what I want and there where some little alignment imperfections that I didn't manage during the glue up so I'm really looking forward to remodeling the parts and refining the design for another go. The ride is really incredible! Way better than I had expected! I can't wait to get it in the woods and push it around but my back is F*#!ed right now. I did spin a few 180s and it seemed way easier like the board turned into a flywheel that wanted to spin and had inertia. Maybe 360s are possible with enough skills!0_1458367805985_1227.jpeg 0_1458367828215_1234.jpeg0_1458369137189_1262.jpeg 0_1458369149592_1248.jpeg 0_1458369159854_1255.jpeg



  • @ashewheeler Crazy! Digging how it looks! Looking forward to hearing more.



  • @ashewheeler wow dude ! this looks awesome :) was it hard to swap the sensors or absolutely manageable ? also, did you use a spare pair of pads that you had "laying around" or the originals ? if you want me to, send me the "new" measurements of your widened pads and i'll send you two dxf files. my W shaped pads and your widened (also with a W shape) so you can try that too if you want to.

    what do you think adds most to the difference in riding ? the concave or the widened deck with increased leverage ?

    sorry to hear about your back man. that really sucks. hope things get better ..



  • @chabis that sounds awesome! Sensor swap is a little intimidating but really easy. I will make a video of swap when I convert my wife's board next week. Basically you have to heat with heat gun and peel off first the grip tape and then the sensor and shim pads that go above and below sensor to create even height. You also have to dissect some hot glue where the wiring from the sensor passes through the board to the underside. I honestly think it is a combination of concave and increased width that feels so good. Where the factory deck sometimes feels like you might misplace your foot or get rattled off position the widened deck feels like your feet are fully supported and firmly situated. I really think it improves overall ride substantially. I toned down the concave and wish I hadn't feels like it would still be comfortable with deeper concave. I knew I would want to improve but wanted to try a full assembly and sensor swap and just confirm it was possible. I swapped sensor from my original and fairly worn out pads. They peeled easily and retained their adhesive so reinstalling was a snap. Can't wait to get you riding concave @chabis!



  • Alcohol dissolved hot clue perfectly, just a tip!



  • @ashewheeler The talent on this forum is incredible! Do let us know how it handles the trails once you're able to!

    I agree there is so much talent out there. I can't wait to see what other great ideas spring out next.



  • Can't wait to see this in person next time we get home to Asheville. Looks great!
