Home Made Helicopter From Scrap

Farmer uses scraps of metal to make his own home-made helicopter… and even manages to get it 40cm off the ground

• Farmer Li Housheng, 52, from Ganzhou Village in Miluo, China, is determined to get his DIY aircraft flying
• He started building his very own two-rota engines last year using a dismantled motorbike
• Skeletons are made of angle iron and stainless steel tubes and each rotor is simply a welding of four steel plates
• During a test flight, Li claims he managed to get the ramshackle contraption a staggering 40cm off the ground

His friends keep telling him it will never take off.

But in the face of those who doubt him, farmer Li Housheng, 52, is determined to get his makeshift helicopter off the ground.

He began building the twin-rota aircraft at his home in Ganzhou Village of Baitang Township in Miluo, China, last year, using an engine from an agricultural motorcycle 

The skeletons are made of angle iron and stainless steel tubes while each rotor is simply a welding of four steel plates. It even includes an accelerator, a clutch and a joystick, all of which come from an agricultural motorcycle. 

The helicopter recently completed a test flight with the fuselage hopping a staggering 40cm off the ground, according to Li.

How to Build a Go Kart

Nothing channels the inner speed-demon like tearing around on a go-kart. Building one yourself from a kit or from scratch can be a highly-addictive project, a fun garage activity for amateur mechanics of all ages. Depending on your access to the necessary tools, you can learn to plan a cool go-kart design for yourself, weld together the right kind of chassis, and make the beast move. See Step 1 for more information.

Part 1 of 3: Planning Your Project

1. 1
   Draw up detailed plans for the go-kart you want to make. Go karts can be many different sizes, shapes, and designs. These homemade vehicles are amenable to any design elements you want to throw into it. The basic essentials are a chassis, a simple engine, and a steering/braking system.^[1]
   • Get creative in your planning for the project and produce detailed diagrams to make sure you get enough materials to complete the job. Look at other go-karts for inspiration and learn from kart-makers who've been there before.
   • Alternatively, you can find schematics and plans online for many different types of models, if you'd rather let someone else do the planning. Use a template and modify it as you see fit.

2. 
   2
   Size the go-kart appropriately. The size of the go-kart should depend on the age and size of the driver. For young drivers, about 30 inches (0.76 m) wide by 50 inches (1.3 m) long will work, while adults will want about 40 inches (1 m) wide by 72 inches (1.8 m) long.
   • It's important to plan the go-kart accurately, using specific measurements, otherwise it'll be difficult to get the right materials and the right amount of them.
3. 
   3
   Gather your materials. If you're short on cash, visit a scrap yard and see if you can pick up any low-cost parts. Or, you may be able to salvage parts from an old riding lawnmower or a junk go kart found at a yard sale. Ask lawn mower repair services for spare parts or junked out riding lawnmowers and used 4 cycle engines in the 10 to 15 horsepower range, with horizontal shaft and a drive clutch assembly. Here's what you'll need:
   • For the chassis:
     • 30 feet (9.2 m) of 1-inch (2.5 cm) square tubing
     • 6 feet (1.8 m) of 0.75-inch (2 cm) round steel barstock
     • 6 feet (1.8 m) of 0.5-inch (1.5 cm) bar stock
     • 3/16-inch (0.5 cm) thick steel plate in a width and length slightly larger than your engine
     • Plywood or metal (for seat and floorboards)
     • Seat
   • For engine:
     • Engine (try an old lawnmower engine)
     • Chain that fits the sprocket
     • Bolts, washers
     • Gas tank
   • For the drive train:
     • Wheels
     • Steering wheel
     • Gear and handbrake
     • Drive shaft
     • Bearings
     • Steering shaft
     • Brake pedal
     • Throttle/go pedal
4. 
   4
   Obtain a welder. If you've got no experience welding, you will have to hire a welder for this project. The most essential part of the go-kart is a solid chassis that'll hold you onto it while driving and house the engine. If you're going to weld it together out of pieces of barstock, the welds should all be made with the proper heat, weld depth/penetration and uniform weld-beads. Otherwise, the welds may be weak, brittle, bubbly, cracked and/or only surface deep, making your go-kart a death trap.
   • If you don't have experience welding, don't start by putting together a go-kart. Start with other smaller projects if you want to learn.
5. 5
   Consider buying a go-kart kit. If you're not interested in welding and designing your own go-kart, purchase a no-weld kit that you can put together with simple tools, featuring detailed instructions and schematics to make the job a snap.^[2][3]
   • Available widely for about $550 dollars, you can have the satisfaction of putting together a go-kart yourself without the hassle of designing it and buying all the materials separately.

Part 2 of 3: Building the Chassis and Steering Column

1. 1
   Cut the metal tubing. Cut your lengths of tubing to the appropriate lengths, given your design or schematics.
   • For most designs, the front end will feature a camber angle, narrower than the rear, which will allow the wheels room to turn, allowing the chassis to twist slightly. To do this, mount a King Pin at the front corners where the wheels will be, to allow for easy twist.
   • For an easy eye-guide, consider marking up the floor of the garage or the area you're working with sidewalk chalk of the appropriate measurement, to keep you from having to remeasure repeatedly. You could even draw out the whole design on the ground and start laying it on top.
2. 
   2
   Weld the frame together according to your design. Use concrete blocks to keep the frame elevated while you work, making sure all your connection points are solid and the chassis is secure. It needs to be strong enough to hold your weight and the weight of the engine, so it's not the time for a shoddy weld job. For more strength, use gussets at all corners.
3. 
   3
   Assemble the front stub axles. Build your axle with a straight piece of 0.75-inch (2 cm) steel rod, and two bushings attached to your frame. Use washers and cotter pins drilled through the axle to keep the assembly in position.
   • Install the front stubs that'll allow you to turn easily before messing with the steering column and attach your King Pin, to the steering arm. You'll need to have at least 110 degrees of angle on the front wheels, so plan accordingly.^[4]
4. 4
   Install your rear axle and wheel assembly. You'll likely need to assemble a axle carrier with a bearing bracket for the rear axle, meaning that the axle itself can be welded to the frame while also spinning freely and snugly.^[5] Weld a steel plate onto the chassis, securing the pressure plate outside with high-tensile bolts and lock nuts, to squeeze the bearing.
   • Rather than making your own, you can also purchase these assemblies, sometimes called "Pillar Bearing Units."
5. 
   5
   Build your seat and floor boards out of plywood lumber or metal. You can try and salvage an old go-kart seat or an appropriately-sized car seat from the junk yard to save money, or just build a simple bucket with a cushion for support. Leave enough room for the steering and other controls.

Part 3 of 3: Mounting the Engine and Steering Column

1. 
   1
   Install the engine mount. Weld a flat piece of 3/16-inch (0.5 cm) thick steel plate to the rear frame to mount your engine. Place the engine on the plate, and mark the holes for the mounting bolts so that the engine pulley lines up with the drive pulley on your axle.
   • Attach the drive pulley on the axle prior to mounting the axle in the bushings. You can either use a set screw to hold it in position, or weld it directly to the axle, but it should be aligned with the pulley on your engine.
2. 
   2
   Assemble your steering linkage. Use the 0.5-inch (1.5 cm) steel rod for linkages, and the 0.75-inch (2 cm) for your axles. To make the 90-degree bends in the 0.75-inch rod, you may have to use a torch to heat the steel.
   • Provide adjustable links for aligning steering, because it is very important to have the proper caster and camber: front-wheel vertical and steering tilt.
3. 3
   Install the wheels and brakes. Get some small racing wheels to give your kart the optimum acceleration and control. Fix them onto the axles with hubs and start working on the brakes, so the go-kart will be safe.
   • For the brakes, fix a disc onto the rear axle and a caliper assembly onto the chassis for the most professional system possible. Often, you can acquire these assemblies in relatively good shape from junked motorbikes. They're the appropriate size and will be easy to work with.
   • Install a brake pedal to operate with your foot, regardless of what kind of acceleration you have. Don't leave too much to do with your hands other than steering.
4. 
   4
   Attach the throttle cable to the hand throttle. Depending upon your experience and the kind of engine you're working with, you may be able to put together a foot pedal, or you may just need to make it easy and throttle-up like you would a lawnmower.
5. 5
   Double check your brakes and suspension system before test-driving. Even if you're going at relatively slow speeds, it's important to make sure you're not going to slip an axle on your first go-around. Double check your welds, your brakes, and the engine's mounting. Then take 'er for a spin!

Worlds cheapest car Bajaj RE60 beats Tata Nano

Bajaj RE60 Preview

One launched the Bajaj RE60 will be new cheapest car in India and in the world – that is if you consider it a car. Bajaj does not. Last year at the unveiling the company said that it is a four-wheeler, but not a car. If you ask us, it has four wheels, petrol engine, space for almost four people and rest of the mechanicals similar to a car. So yes to us this is a car, but an absolutely quirky one.

The RE60 has been in news for a while. Originally, Bajaj was supposed to just manufacture the, while the car was to be marketed under Renault-Nissan alliance. But half way through, the French-Japanese conglomerate developed cold-feet and the two-wheeler giant decided to proceed on its own.

The RE60 was revealed last year at the 2012 Auto Expo and looks more like a safer substitute for the auto rickshaws than a proper car. In fact, Bajaj is expected to sell variants with 1 + 3 seating specifically for the commercial market. However, the company will also sell a version with 2 + 2 seating.

The RE60 is the most appropriate replacement for two-wheelers. It is expected to cost less than most 250cc bikes available in India, have similar fuel efficiency and have ability to carry four people. The RE60 willbe powered by a 200cc DTS-i engine, the same mill that sat in the original Pulsar 200 motorcycle. The engine will produce 20bhp and propel the RE60 to a top speed of 70 kmph with a fuel efficiency of around of 35kpl.

The production version of the RE60 will be pretty similar to what was shown at the Auto Expo except for changes to the rear.The glass windows will be replaced by a fabric cover and the metal hatch door will be replaced by a plastic one.

The RE60 will have features like the central speedometer cluster, dashboard mounted shifter, folding front windows and 44-litre boot space. The private variant may also sport alloy-wheels, but rest of the details are expected to be bare-basic.

The RE60 has been spotted testing several times and we expect Bajaj to launch this model by the end of second quarter of this year. The prices of the RE60 are likely to start around Rs 1 lakh, while the top-end private variant will be close to Rs 1.5 lakh.

India’s Bajaj Auto unveiled its first four-wheeled vehicle named RE60, making a foray into the wider market from its comfort zone of two and three-wheeled vehicles.

The RE60 will be built at Bajaj Auto’s Aurangabad plant and the launch will take place in a few months from now. The company refused to divulge the price. However, it said that the RE60 will deliver close to 40 kmpl and emit only 60g/km of CO2, making it one of the most fuel-efficient and green vehicles in the market.

The Bajaj small car RE60 is reported to be installed with liquid cooled, DTSi, four stroke, single cylinder, 200cc motor that will churn out around 20 bhp max power along with 35 kmpl mileage. Apart from that the new vehicle from Bajaj has got seating for 4 passengers including driver. The max speed limit of the passenger vehicle will be 70 kmph.

he upcoming Bajaj ultra-low car will have head-to-head competition with the India’s cheapest and smallest car, Tata Nano. There are no official words concerning to the forthcoming Bajaj ULC car, except the few core technical details. The fuel efficiency of this Bajaj car will be pretty impressive.

This car will have powerful integration of highly-efficient 800cc petrol engine that will offer impressive performance.

Pick Up and Acceleration
However, company’s officials refused to talk about the technical and other sophistication of the sensational Bajaj ULC car, still if words are to be believed, the futuristic Bajaj small car will offer a great pick-up and acceleration. It would be somewhat equivalent to the pick-up and acceleration offered by the Tata Nano.

Interiors and Features
Despite being a compact car, Bajaj small car will come with enough spacious interior. The only significant difference will be, passengers will sit a bit closer to each other. The leg room, head room and elbow room will make it a good deal. The interior built quality, comfort, rich features & upholstery will take a charge on Tata Nano’s interior.

The driver’s seating position will be comfy and offer fine outer visibility. It is good enough to accommodate a young family. We can expect the functionally efficient accessorial features including the dashboard, windshield, steering wheel, centre console, Air conditioning units with adjustable AC vents, speedometer, digital fuel meter, odometer, cup holders, power socket & buttons, power windows, soft fabric seat & door covers etc; but official confirmation is still required.
