How to make wheels for a car or robot
Hi all! Many DIYers who make cars or robots have encountered the problem of not having enough wheels for the model. I've been looking for a solution to the problem for six months now. Since I'm into robotics using Arduino, I often need wheels of different diameters. I'll show you how easy it is to make wheels.
To make them you will need:
-foam plastic of the required thickness (I took 30 mm); - cardboard rectangles (during the manufacturing process you will understand how long and wide they should be); -PVC tube with a diameter of 5.2 (or any other, it is used to secure the wheel to the engine); - titanium glue or equivalent; -gouache paint; -and some little things that everyone has.
The main tool is a nichrome cutter. They will need to cut out circles from foam.
Be patient and you can start.
In the future I will make a robot using these wheels.
I hope you liked this idea. I believe that this is a worthy homemade replacement for purchased wheels, in any case, I did not find a single idea on this topic on the Internet.

Sequence of installing wheels on a wooden toy
Today I’ll tell you about the sequence of actions when installing wheels on a wooden toy and I’ll write a simple “formula” for calculating the length of the axle.
You can watch the video.
Below are step by step photos.
1. Prepare the wheel. We drill a “blind” recess (hole) of 8 mm in it.
The diameter of the hole in the wheel = the diameter of the axle.
It is important not to drill through the wheel, as you will have to seal the axle from the front side.
2. Apply a drop of PVA Moment glue into the wheel recess and install the axle at half the size of all wheels.
The formula for calculating the length of the axle = (depth of the hole in the wheel X 2) + 2 mm for gaps (between the body of the toy and the wheel) + thickness of our workpiece
In this example, I installed wheels on a machine with a body thickness of 40 mm, made holes in the wheels 8 mm deep, and a gap for free rotation of the wheels (between the body and the wheel) of 1 mm on each side.
Accordingly, I cut the axles with length = (8 mm x 2) + 2 mm + 40 mm = 58 mm
3. Using a screwing motion, I spread the glue and at the same time insert the axle into place in the wheel.
It is important to ensure that the axle and wheel are perpendicular.
To check and level the 90 degree angle, I roll the axle and wheel along the edge of the countertop surface.
Let the glue harden for some time. Repeat the operation for the wheels of one half of the toy
4. I pass the axle with the wheel through the workpiece and apply a drop of glue into the recess of the counter wheel.
Using the same screwing movements, I insert the axle. Here it is no longer possible to use the previous method of leveling on the edge of the table, so you can prepare a plate 2 mm thick.
After installing the second wheel, slide the plate between the workpiece body and the toy wheel to make sure that these parts are perpendicular.
With experience, this is no longer necessary.
Correctly and evenly installed wheels are the key to high-quality and smooth movement of a toy on wheels.

DIY radio-controlled racing car model
Good day, lovers of making things with their own hands. In today's article we will collect a rather interesting homemade product for your leisure and fun. Namely, we will assemble a radio-controlled model of a car. One of the key features of this homemade product is that it will be assembled from the most homemade and affordable components using a minimum number of purchased factory elements. This homemade product can in no way be classified as a serious model, but it can easily outperform any toy model from a children's toy store and, in addition, have greater functionality (in terms of the number of different settings). This homemade product may be inferior to toys only in appearance, but here everything depends on you.
You can find links to some of the design components at the end of the article.
For this radio-controlled car model you will need the following, namely:
— Metal axles — 20mm plastic pipe — Bearings — Wheels 4 pcs — A small piece of rubber (for example, from a bicycle tube) — Aluminum profile (the one used for installing drywall) — Electric motor — Small sheet of plywood — Plastic ties — Metal washers — Bolts — Nuts — Sheet PVC plastic - Servo drive - Speed controller of the commutator electric motor - Rechargeable battery - Radio control equipment with its own receiver - Ordinary corrugated cardboard
In the case of the author, there were no difficulties with installing the bearings on the shaft; their diameters clearly coincided, but I had to tinker a little with the outer housing of the axle in the form of a plastic pipe. Since the bearings did not fit into the pipe, and they were only a couple of millimeters short, the author decided to take a step drill and slightly enlarge the holes along the edges. Afterwards, armed with a hammer, I managed to hammer the bearings into the pipe (see photo). Although the bearings fit tightly, it is still necessary to additionally secure them with superglue. We insert the axle into the bearings and move on to the next step.
Craft machine - manufacturing diagram and features of choosing machines from scrap materials (85 photos)
Today, looking at the world of adults, full of cars, boys and girls from childhood want to have their own cars, even toy ones. However, you don’t have to buy them; you can make a craft car from plasticine, paper, cardboard and other materials with your own hands.
There are many techniques and methods. The main thing is to interest them in such handicrafts. Read more in this article.

Features of self-made cars from paper
To create a paper machine craft, you can use either ready-made diagrams taken from the Internet, or use your own imagination and come up with something of your own.
In addition to plain white paper, it is advisable for you to purchase a set of colored cardboard, glue, markers and pencils. You may also need wooden sticks and matches.
Low pressure wheel manufacturing technology
First of all, you need to get rid of the wire cord. To do this, an incision is made on the sidewall of the tire, the cord is cut with cutters and stretched along the entire perimeter of the wheel. After removing the first layer of cord, the standard tread is pulled off using a winch. To do this, fix the tongs on the incised area, load them with a winch and trim them with a sharp knife so as not to remove the excess layer of rubber.
When the tire is processed, a new tread pattern is applied, depending on the operating conditions of the future wheel. The protector is cut with a sharp knife. When the tire is ready, the disk is assembled.
At the same time, they try to make the design as light as possible. Examples of such homemade disks are shown in the photo.
After this, the wheel is assembled, the chamber is inflated to the required nominal pressure, and rubber bands made of reinforced conveyor belt are used to securely fix the tire to the disk. Here is an excellent example of exemplary homemade tires installed on welded wheels on a UAZ 469.
Ready-made wheels can be used on swamp vehicles, ATVs, snowmobiles, and regular off-road vehicles. Happy experiments everyone!

Cardboard roll machine
Let's consider the most popular example - a diagram of a craft machine. It is quite simple to implement it. Even your baby can handle this.
For tools, prepare scissors, a brush, a compass, and a ruler.
Fire engine
Assembling the product is not as difficult as it might seem at first glance.
Connect the boxes using tape. Make wings from cardboard rolls. Place paper napkins on the surface of the workpieces.
Make a hole for the compartment with the hose and the compartment itself using cardboard, string and a suitable button.
Insert it, cover the wheel blanks with corrugation and cover the ends with circles cut out of cardboard. Make a radiator grille and bumper.
Paint the wheels and corrugated elements, glue the door to the one that will open onto a piece of fabric - this will ensure its mobility. Make a stopper on the inside using a plastic lollipop stick.
Paint the entire car, add the necessary details. Don't forget to make the back ladders of cotton swabs and the two top pipes from tubes wrapped in foil. The craft is ready!
Advantages and disadvantages
Wheels have many advantages over purchased wheels:
- Price. All-terrain wheels are very expensive, which can’t be said about the wheels.
- Such wheels have excellent adhesion to almost any surface, which significantly reduces the risk of accidents.
- The husks weigh relatively little. An “unpumped” passenger car engine will be quite capable of cranking them.
- Low surface pressure due to the large tire area. With encouragement, muddy terrain, quicksand and deep snow become quite passable obstacles. The tire pressure on the surface can be adjusted. They just need to be pumped up or lowered a little.
- Tires with low pressure do not harm the surface soil layers in any way, so you can safely drive an all-terrain vehicle with tires across plowed fields or use it as a tractor in agriculture.
They are also not without some disadvantages :
- You should try to ride less on hard asphalt and concrete surfaces. Otherwise, they will have to be changed very soon .
- A car on such wheels is not very stable. It’s better not to make sharp turns on it, and you shouldn’t drive it fast at all.
- Wheels wear out much faster than normal ones.
- Encouragement is a considerable burden. Transmission and suspension parts with such wheels will have to be changed and repaired more often.
- Low pressure tires are very flexible. This increases their permeability. But due to their increased stretchability, tires get punctured more often than regular tires.
- The car will have to be re-registered - “upgraded” to the status of an all-terrain vehicle.
Advantages of cars made from waste material
As children age, their interests change. If at one or two years old a child is happy to have one car of the simplest model, then, as he gets older, he will be interested in toy cars of a more complex design.
In addition, he will want to create a whole fleet of vehicles. For a parent’s budget, such a desire for a child can cost a pretty penny. The solution is to manufacture vehicles from waste materials.
In addition, such creativity helps to form children's fantasy and imagination, as well as develop fine motor skills.
To create a car craft with your own hands, you only need to have desire and free time.
If you want to do something useful on winter evenings, then start making toy cars for your child.
You can also involve the child himself. Crafting together is always more interesting. Offer, for example, to create a craft car of the future. Time will fly by.
