Step 7: Create the friction wheel

The friction wheel I first created was inspired by the bike powered blender instructables from the following link: http://www.instructables.com/id/STTOO5AFGWRG4LN/ or search "How to create a smoothie making human powered bike blender for less than $25"

1. I got two wooden 1.5 inch wheels from Michael's
2. I drilled a hole throught each of them
3. Pound two tee nuts into the wheels
4. I threaded them onto the all thread shaft I had made. and glued them together with wood glue
5. With some rubber from a broken bike inner tube I pulled a piece over each wheel and overlapped them coming from each side. If you can get the tube over both it is ideal.

This is the friction wheel I used. It worked ok, but because the wheels were not perfectly aligned since I drilled the holes through them myself, they didn't put even pressure onto the bike wheel and therefore caused uneven pressure on the shaft and a net loss of energy so this an area where improvement can definitely be made. Ideally the friction wheel woule be flat all around and strong enough to stay even along the bike wheel throughout pedalling.

So like a metal cylinder with like grittiness to it like a file that would be the friction against your bike wheel.
Why are you wearing a helmet in step 3 using tools, but not in step 10 where you are actually riding a bike?
<p>That is exactly the question that sprung to my mind...</p><p>Anyway, hilarious project, made my day</p>
Great idea - but the only drawback I see is having to cock the leg up to shoulder height - before spinning it over the frame while mounting the bike - unless of course, you forget...<br> <br> &quot;Arrrggghhhhh dammit! That is the third blender jug I have broken this week...&quot;<br> <br> Etc.<br> <br> Perhaps a tough plastic bag and a pounding with the fist might make a good blender..<br>
If you could paint as well, you would be able to paint, exercise, and make blended drinks: <a href="http://www.youtube.com/watch?v=PvbL_5rH1QQ" rel="nofollow">http://www.youtube.com/watch?v=PvbL_5rH1QQ</a><br>
cool ible im getting a bmx in a couple of days! :)
tandem? anyone?
Forget the bike, where can I get me one of them there hats! (Pardon the bastardization of basic grammar, but it doesn't really portray the feel I was going for...lol)
into page picture 3 I swear I saw the guy in the green shirt before
Great build! How many RPM do you reckon the blades will reach? L
Cool good instructable A++!
a new look at healthy eating :) great. :)
I'd like to see this turning up on cookery shows;<br/><br/><em>&quot;Give the ingredients about 3 miles in the blender...&quot;</em><br/><br/>
Hilarious, but I'm gonna keep this one down on the list.:)
