This is a new project, come and race with us! The next event is October 19th at the Wells Fargo Center for the Mini Makers Faire. We will have transformation stations to make your bike "PIXIETASTIC!?!"
Well, its been quite a few months since we raced at Maker Faire, and it took long enough to get this video up, frankly we were all exhausted. We are planning on doing it all again in May, with some pedal car building workshops coming up (here in Sonoma County).
Please make sure that you look back in this blog to find the build requirements and restrictions before you start welding.... we will be rejecting cars that obviously do not meet some of the most basic rules... like the NUMBER OF WHEELS!
This video is of the "Man vs Machine" race, meaning that it is Pedal Cars and Power Wheels racing at the same time. Believe me, it moves really fast when you are out there, even is we look like snails in the video!
We raced all day Saturday and Sunday, every other hour we had 2 heats per hour. We also had one race at the end of each day that was "Man Against Machine" -pedalcars vrs. powerwheels.
Race results and more photos and videos will follow in the next few days!
Sometimes we like to do things the old way, and this banner shows it. The fonts were supplied to us by Kathie Sever, they were carved wood letter type from the late 1800s, she printed them on paper for us a couple months ago. We put the print on the opaque projector and my daughter traced the letters onto the canvas. We painted all the color with acrylic paint, and then Joshua sewed the border and the backing. This is just one example of the path that we choose to take.
Bruce just rolled up with his new car, working title is the Clean Machine.
This car has a lot of clever solutions for store bought parts, like the forks-become spindles,
and the excercise bench-adjustable seat with head rest. Also a great use for an aluminum
box tube as main frame member.
We look forward to seeing him at the races and at the faire.
Josh found this website with some great black and whites of kids and Peddle Cars, there is some good inspiration in these pictures. Just 23 days till we race, and we hope that you are putting on the last touches, or at least begining to think about brakes.
You have seen those jogger/walkers all over, you know the kind with three wheels and some sort of nylon bag support with a sun shade over the top. In our neighborhood the homeless guys have started turning them into trailers for their stuff. Well I had a couple in my yard and finally took a good look at the rear wheels; it ends up that the plastic locking brake and all the trim pieces come off to leave a hub that takes a simple bearing, in my case I just salvaged the bearings that came with. In my case, the bearings fit a 1/2" bolt, or spindle. If you need different bearings, these can be pretty cheap, I have seen them called: insert bearings, flange bearings, wheel barrow bearings. These wheels measure 10"and 12", and i cant really testify to how these will work, but they show promise, and they are FREE.
Klaus brought the Sederholm Speedster to the races last year with just the top "hood" of sheetmetal on the car. He's working on the rest of the bodywork this week; 20 gauge mild steel welded to the frame tubes, hammered over the edge and welded and ground smooth. Hopefully he's adding a lot of weight so he won't be as fast as last year.
As of today there are only 35 days left until the races!
Some of us are one wheel drive, some of us are using a combination of free-wheels to get power through the corners at all times,kind-of like a differential ... but not quite. This is an explanation of how a differential works from 1937......it all makes so much more senses now. It is a 9 minute video, but so worth it.
but this was printed by our friend Kathie Lebec Sever who works at the Rob Roy wood letter type collection at the University of Texas. These letters were hand carved in wood over 100 years ago. Look for more of our stuff with these on them.
There is alot going on with the left rear of this pedalcar. First, the arm that goes on the outside of the wheel comes off with two bolts to access the tire. The brake caliper is mounted to that bar, and the handle shares the shaft that has the transfer axle sprocket, that handle also has the twist-shift for the derailer. Crazy, works really well. This car is one wheel drive, and one wheel brake.
Speaking from experience, brakes are the last thing I put on a vehicle, thats not saying its the best way to go about it, just what happens. Here are a few examples from three different cars built last year, on their way back to the course this year.
This is Todd Barricklow's #3 racer. One wheel brake only, the left. The Aluminum spacer is through bolted onto one rim, and the bicycle disc mounts to it. The brake caliper is cable actuated, and must be tilled out of the way, in order to remove the wheel. Stopping power is a good stop, as long as the left wheel is on the ground.
This is some of the parts from the Carsophogas. Dual front disc brakes, cable actuated. Last years plastic rim is on the bottom of the stack, this years spoked rim is in the middle, and the pvc/disc/bearing insert is on top. His challenge this year is to make all 4 rims interchangeable, but the front and rear axles are different sizes. This means a custom disc plate that can be put on with 2 different bearings.... I dont know if he has it figured out yet.
The Sederholm Speedster has dual rear brakes, cable actuated. A mounting disc similar to the above one on the #3 was made out of steel, and through bolted in a similar manor. He has a similar bolt that removes to tilt the caliper out of the way. This car stops really well.
These are all bicycle disc brakes, not the cheapest approach, but a good stop. There have been some other brakes used, and they will be featured in a later post.
This is one of the videos that got posted of last years races, as of today it is 54 days and 12 hours until the start of the next race day. This video has footage of the crash that stopped the "Carsophogas" for at least a few more races that day. The Sederholm Speedster crashes right into the plastic wheel around the turn of the eight. That is where most of the collisions were that year, not in the "X" of the track.
As some of you may know, we will be sharing the racecourse at Maker Faire with the Power Racing Series. These folks take the little kids plastic electric toys, and then they hack them into racing machines. They are all tech, and it will be fun to share the whole space with them in the pit for the weekend. They have a little video for this racing season:
I know that I watched this video a bunch last year, and laughed almost as much as when we raced.
A pedalcar "race" from England from the 1960's, there are some brilliant vehicles in here.
check it out:
This is a description of the requirements for the Pedal Cars. Application form will follow soon.
CART RESTRICTIONS: Four wheels.
Must have brakes!
No larger than 50"wide x 70"long wheelbase.
Your pedal car body can not be more than 4" wider and 20" longer than your wheelbase.
You may not race a stock store bought vehicle.
No sharp edges.
Nothing designed to harm other racers or vehicles.
The goal here is fun!
Race winner is the first one to complete the designated number (7 or 8) of death defying figure 8 laps. Poor sportsmanship will not be tolerated.
You must wear a helmet!
And, have fun!
The primary race will be the Death Defying Figure 8 race.
Depending on race day realities ie; available space and number of cars on site.
We may have time trial drag races on the slalom course and straight track and/or an "everyone in" oval track rally.
The goal - to have fun!
ON RACE DAY:
There will be a brake and steering test on race day. (You and your vehicle must arrive and register on Friday, 5/17)
Your car must complete a short slalom course and be able to stop in the designated stopping zones.
The Race Official will have the final say if the vehicle does not meet the safety requirements of the death defying challenge.
There will be a race official.
He/she will have the final say.
There will be a pit area provided for each vehicle. There will be a dunk tank...
The goal here is Fun!
