Step 1: Materials

Here is the basic list of parts. The dimensional lumber is estimated because I had enough scraps to cover that. I ripped the various sizes needed on my table saw from larger lumber.

(2) 4' x 8' sheets of 3/4" Plywood (I used BC Exterior grade)
(1) 4' x 8' sheet of 1/2" Plywood (I used BC Exterior grade)
(1) 2 x 4 x 6' pine board
(1) 1 x 6 x 6' pine board

Surplus Center Parts

(2) 10' pieces .40 pitch chain (#1-1163-40)
(2) 11 tooth 7/8" shaft sprocket (#1-2123-11-D)
(2) 30 tooth sprocket. (#1-2123-30-4B)
(4) 7/8" dia. shaft collars (#1-2766-87)
(2) #40 Chain Connecting Link (#1-1087-40)

(4) 7/8" I.D. bearings (eBay)

6' of 3/4" heavy wall copper tubing
4' of 1" thin wall copper tubing.
(12) 3/4" 90deg copper elbows. (buy a bag/box of them...much cheaper)

26' 5/8" I.D. Heater tubing
5/8" double barbed fitting.
1/8" NPT Schreader tire value
<p>Wow! Nice!</p>
<p>did someone already buy it?</p>
<p>have u thought abut puting a tiller on so 1 person can control it</p>
My dad has two antique 54&quot; steel hay machine wheels taht I am going to try to use for this.
This looks like sooooo much fun. totally awesome!
Wow! Really great! Thank you for the Inspiration! That would be great for my little kids :-)
Hi ! soo i saw your steampunk design and i think is awesome .... would you mind if i try some different style for the design ?
Admin on this site must be smoking Meth this should of made in the top five of&nbsp; 09. it did make it as 13&nbsp; out of 50&nbsp; still not bad ! but still yet it should be in the top 5<br />
agreed. except for the meth smoking part. i dont think they do that.
What about &quot;Weird Wheeler&quot; as a name?
Awesome! I made something similar (3 wheeled) several years ago, nowhere near as cool though!
It is still going strong after two years!<br><br>I am looking to clear it out of my garage. It takes up too much room. If someone in the Chicago area wants it, make me an offer.<br><br>The kids are going to be a little upset :-(
Great design!<br>
This is really cool and very nice wood project.<br>For the one person version we could use a a V- belt drive with a Variable speed pulley to change the speed of one wheel, so we can control the direction by adjusting the pulley.<br>The V-Belt variable speed pulley are not expensive and it is available for a range of torques and dimensions.<br>
I wonder if there could be some sort of geared steering system for single rider use... I may have to research this...
You could use an individual brake on each wheel and put a diferental between them.
we had to design the bike of the future for my science class, and this is almost the exact same as my design, except mine was a little taller and was only one person. The pedals werent attached to the axle directly, the go to a differential, so to turn you would pull a brake lever or handle, and it would slow down the tire.<br><br>Your design is AWESOME!!
So so cool! And beautiful as well! <br>It's looks like something you would need to wait in line and pay to ride. The worry-wart in me is afraid of any little fingers or arms going into those spokes. Perhaps a little netting or wire would prevent that? <br>Keep building cool stuff!
good job! hey all i have to suggest is make some sort of steel reinforcment that has spokes on each wheel that would meet up and be connected to where the wheel connects to the shaft, i noticed alot of warping between the wheels and the chassis. but still an awsome way to get around!
I noticed the flex too. Maybe thicker axle and perhaps an extra ply or two when making the wheels? Hrm, maybe even a mud guard and make the axle held on both sides?<br> And yeah, still awesome even with the flexing.<br> <br> I'd love to do a single seater version, hand cranked. Would then fit in bike lanes and also be suitable for disabled use as a bonus. I can almost see it but the models I've tried to generate in the PC so far suck.<br> <br> Plus a hand cranked idea adds the option of hybrid human/electric - batteries under the seat for stability<br>
I wonder what the neighbors think of all the crazy inventions rolling down the street xD
the legway's scary older brother...
I&nbsp;love this! I&nbsp;will probably build one over the summer. one thing that I might change would be the two person part. I figure with the right gear box and some hand levers it could be converted to work with the same two wheel pedal powered design but could be much more efficient and could turn without the second person.<br />
This looks like something Government Motors might be interested in.
Yes, someone said this is the Steampunk version of the G.M./Segway Puma.
Yeah, except the Puma is a totally lame electric wheelchair with a windscreen. The SteamRoller is awesome!
agreed<br />
For Non-Eccentric bearings.&nbsp; Try this place.&nbsp; There a bit cheaper but you will have to use larger shaft diameters.<br /> <br /> http://www.thebigbearingstore.com/servlet/the-4-dsh-Bolt-Flange-Bearings-cln-Set-Screw-Locking/Categories<br />
what was the diamiter of the 30 tooth sprocket. i can't find 1-2123-30-4B on surpluscenter.com
What was the total cost of this project?<br />
this is completely Epic!
Do you think it's possible to add a transmission so you could have variable speeds? What I'm thinking of is something similar to what they have on mountain bikes. Also, I would like to see a rack-and-pinion steering setup, but I don't know if you could make the contraption that complex. I'm probably asking for too much. I'm going to have to try to build one of these.
When you say surplus center what kind of store was it and what was the name of the store. I need to find all the "tricky" thing first the other stuff is easy to find
thank you. you were right the surplus parts are alot
How do you install the pedal gear, shaft collar and bearing into the wood? I've never used these before and am not sure how everything stays in place.
The bearings are not as thick as the wood. Drill a hole the outside diameter of the bearing with a spade or forstner bit only as deep as the thickness of the bearing, so you have a flat bottom hole. Then drill through about 1/4" diameter less than the outside diameter of the bearing to create a step about 1/8" all the way around. The bearings should press fit into the wood and sit on the step created. Use some tape to build up the diameter if it is not a press fit. The collars prevent the pedal shaft from sliding laterally in the bearings. Put a collar against the bearing on each side. You could actually use the gear as one collar if your steps are setup to install the bearings from the gear side.
Awesome, thanks again.
Is it difficult to find the perfect spot for the wheel axle in order to maintain the right balance, or will it balance automatically as long as the center of gravity is anywhere beneath this point?
I drew it in chalk on the floor and estimated the CG. Some small kids use a pillow behind them so they can reach the pedals. This shifts the CG forward, so I added a little shelf behind the seat to add weight. So far one 10 pound-ish brick does the trick. Big adults with higher CG tend to ride with feet high, but it works fine.
Thanks! That shelf for extra weights is a great idea.
awsome this will be the first thing i make in woodshop nest year. i already have people ready to ride it down the hallways of the school when it's done
Just make sure you can get it out the door!
Don't worry we have one of those big loading doors plus the outside doors are huge this will so make me in the yearbook
Well done, I've seen your earlier works, but I think this one is the best so far. It looks far easier to ride this one, plus its a social activity to ride on it. Do you let the kids enjoy this one a lot?
It is difficult adjusting the wheels, but really awesome Instructable!
Please Answer ASAP... How much did this cost in GBP?
