Drive system and finished wheel

 These photos show the drive that I am going to use. It is from a smashed up four wheel motorbike. The engine is cactus and that is not the brand name and will be driven threw the crankshaft from the magneto end.

 The photo below is the finished wheel with tyre.

This was my one of my first cycle cars

Alas this was removed from my property and its where abouts is unknown.

The flying feather on wiki

 Flying Feather looks like a modified mini minor to me!

Seen on the net

This is a true cycle car.

Marking out the wheel stud holes

Making the wheels

 This shows the pointer used to find the center after the wheel is set to spin true on the jig, the wheel is not held down as there is no maching to be done.

 This shows the jig made from a wheel bearing held in a vice with the particle board table for the wheel to sit on.

Setting the wheel true in the jig using a stationary hammer handle note the pointer arm (blue) that holds the pointer.

 The wheel mounted on the hub.

This shows the front end and wheels attached.  The front end is ready to weld to the rest of the car. I have to make the rest first.

wheel bolt holes

I have been working on the space saver wheels and have completed three and bolted them to the hubs and they run true. I will get the tyres back on the rims in the day or so. making the new rim centers has been a case of careful marking out and welding. Jigs help. I made a spinning table from a car wheel stub axil assembly with a piece of particle board bolted on with the wheel nuts then placed the welded wheel on this all held in a vice. Then I set about running the wheel true then put a pointer above the wheel to find the true center and marked out the holes with good accuracy. I will get photos up in the next day or so.

This is the rebuilt front end for my cycle car

My cycle car is coming along with the rebuilt front end from a smashed up quad bike that I bought for $40.

Gravity racing

There is another fun sport with small engines

Lawnmower racing is less on construction and more on the fun stuff.
Check out this video http://www.youtube.com/watch?v=5zjMf8JgF6k
then there's this onehttp://www.youtube.com/watch?v=xl0CB6v4QzY

What to make

I saw these on the web and thought it to be an interesting subject.



Then there is this.

Air screw cars

Propellor driven vehicles are a preposition but the draw back is the spinning propeller. I had a push bike with a 12x10 propeller and it could reach 60k/h with a 50cc engine. mine was a pusher propeller.

Wheels

Another day and the wheels are made.
The jig below is made from flooring and carefully marked out.

 Surprise surprise the wheels are not all the same diameter and are from the same make and model and from the biggest to the smallest is a difference of 5mm in diameter.

More to come so keep watching.

Where do you get the right wheels from

I have been looking for the right wheels and found the space saver wheels the right tyre shape and diameter. I cut the centres out and then set about making a jig for the new wheel centres and came up with the wheel in the photo below. Three to go..
