BoardSki/StreetSki Prototype Thing

I got this idea after watching lots of longboarders and looking at some

freebord videos. Keep in mind this is just an idea, no more. What if we

took small longboard trucks, and put them on an enlongated longboard

thing, that was thin like a ski?

You could carve around stuff

well, and I imagine it would open up an entire new door in tricks in

skateparks and stuff. I mean, that would look sick(might have problems

with the wheels catching on the boards when you cross, but screw it).

But it would still be fun to zoom down streets and stuff.

So I

spent an hour drawing a prototype(after drawing them, the brakes seem

somewhat useless. Or maybe not. I guess if they were powder brakes that

were heavy rubber that would be cool):

What

do you guys think? Obviously a lot would change from now until final

manufacturing time, but if it was good and worked okay, would you buy a

pair? Is this even worth pursuing?

Anyway, just an idea I had.

The whole point was to remove the y axis from rollerblades, since if you

lean forward or backward you're screwed. And I was getting sick of no

snow here. Hahaha
 
exposed wheels like that wouldn't really work since the wheels would get all caught up if you put your feet close together
 
That's what I was thinking too. I wasn't sure how to get the turning motion without the trucks doing the work though. :/
 
If there was some way to center a wheel under the ski, and get it to turn when you flex it that would be gold. Mechanical engineers, please speak up. :)
 
Ok damnit. After watching Woodward's videos these would be easy as fuck to build. I already got the press and some K2 blades that I can jack some wheels off of. The design itself; I think it would be easier to have shorter skis that aren't awkward on concrete. Then the wheels, just need to mill some hubs to pass an axle through, then the hubs bolt to each side of the opening for the wheel. Then your wheel layout. You would have a single wheel setup in front, and behind your binding, then a double wheel setup in the tip and tail. Like so: ( = - - = ) Now you can roll the ski on its side and that wheel layout should effectively give you a rolling sidecut and allow you to turn. Inb4 successful summer project.
 
Holy shit thank you so much for posting this. This is exactly what I've been looking for. Yes. Do want to buy these. I wonder if these will ever go into production, or if someone(:D) will need to nab this opportunity.
 
Woodward has like 30 pairs but they've said many times that none of them are for sale. So I guess someone else has to step it up and make them.
 
Yeah, I'm going to try to this summer. If it's successful, I might just make a tutorial on how to make them, and post in on NS. :D So stoked now.
 
Just adding to the brainstorm, but I don't think you'll need the dual-wheel setup in the front and the back in order to mimic a sidecut radius. When putting the ski on edge, it will be the two wheels closest to the boot that are going to create the turning profile. The wheels on the tip and tail are only there to eliminate the problem that rollerblades have of not being able to lean forwards/backwards. A rollerblade can turn by leaning the wheel into it, so this should, too.
 
Something else to think about: 4 axles per ski (one at the tip, one in front of the boot, one behind the boot, and one at the tail). Tip and tail are just one rollerblade wheel each. Axles near the boot have a U-shaped bend in them with 3 wheels on each one. So when you lean right, the center and right wheel touch pavement. This would really let you get on edge and carve it up. But now that I've typed it all out, I guess it wouldn't really be great to try tricks with, just for cruising concrete groomers.
 
Was thinking about this the other day.

Has anyone ever taped 2 skateboards to there feet? How did they handle?
 
like a flowboard

that would be tricky since skis are much narrower.

 
only the funnest skateboard ever. my friend had one when we were like 10 and we would rip it down his road. does not work at low speeds, though.
 
Alright, So I think I'm going to start with the Woodward RollerSkis, and modify them a little. I will probably lift the tip and tail wheels and go with a multi wheel under foot system to get carvyness. So a single small whell in tip and tail for stability, then six tiny ones underfoot(3 and 3) all angled for carving. Maybe I can shove some springs in it for maximum carve flex. Small piece of metal added as well underfoot to keep jibbing smooth, you know.

I don't know. I'll just slap some shit together and throw myself down the street with my eyes closed. Hope for the best. The first prototype WILL look retarded, so keep your fingers crossed.

 
THREADS

I'm a mech.eng student, and this is a very cool idea. I think that Woodward got it right, and I think this picture pretty much sums up the basic design of the skis:

Per 1 ski:

- 4 Rollerblade wheels, parallel to the side cut of the skis equidistant center. (for side cut)

- 2 skateboard wheels, equidistant from center (for bottoming out)

- Reinforced underfoot for durability on rails (Fischer made skis like this a while back)

- Ski bindings (obviously)

Things to note:

- After drilling the holes and mounting the axles, I would reseal around the holes for safety purposes.

- skis should be symmetric & stiff

GOOD LUCK! if everything turns out I'll probably end up making a pair myself

My dad experimented with these quite some time ago for Atomic. The result was a sketchy metal ski thing that was 90cm long and worked great for Xc, but anything downhill = death.

To turn you basically had to shuffle your feet or skate.

inside the box there are a shitload of old skateboard wheels, so I may try this myself if I can find my old skateboard so I can take the trucks off of it.

 
i would NOT recommend these because you are unable to carve and have to do side step turns. you can grind though haha
 
If I press a fucked up ski this summer I will most definitely try it. We have a little portion in town that would be perfect for testing as well.
 
I looked around the internet for flowboard but i can only find them ebay or amazon, or random website with no guarentee of authenticity...anyone knows where to get those in Europe, they seem doooope!!
 
I actualy thought of making a similar ski thing before I saw this thread, however my idea was more focused on urban, especially rails. You guys think it would be a good idea actually trying to make it from a real pair of skis?And do you think using ski boots/bindings would be better than making straps for normal trainers??

Anyway, probs gonna start planning and building a prototype quite soon, hope it works out.
 
For a prototype I would just go with a plank of wood, and not really worry about flex and that shit unless said prototype worked.
 
i tried this a few years ago by drilling skateboard trucks to the bottom of strait skis.. did not work hahah

threads if this way works out
 
Awesome.

This is what I think I will try. Only, I'll increase sidecut a bit more to provide more turning, but not so much the wheels' physics counteract each other ineffectively.

WILL be posting a thread updating you guys on the progress of this. I just need to muster up around $150, and it should cover everything. Was planning on making the actual skis from scratch, probably a laminate of wood and plastic and shoving in a press.

I hope to god this works. Summer blows. Plus we could totally transform skate parks. It would be dope.

Wish me luck everyone.
 
What if you took a pair of 151 skis and put two side by side wheels in the front right before the tip rises and the same in the back. using a stiffer ski of course. so you would still be able to slide rails and ollie&nollie onto rails. also you could experiment with putting a single wheel in the front and back of the bindings.
