We recommend installing axles with a 1.5° bend for the front of the car and 2.5° bend for the rear. The axles heads are marked in the direction of the bend. Install the axles with the mark straight up.
Can you bend Pinewood Derby axles?
Use bent polished axles.
Bending your Pinewood Derby car axles with a bending tool will make the wheels ride up against the nailhead, which creates less friction than if the wheel is bouncing around and rubbing against the wooden Pinewood Derby car body.
What is the best angle for a Pinewood Derby car?
Some of the derby dads that I’ve talked to say that 1/2 to 1 degree is the way to go, just enough to get the wheels to gravitate out. I know lots of people hold 3 degrees as kind of a standard.
What angle should CV axles be?
Depending on the specific manufacturer, a typical outboard CV joint will allow a maximum articulation angle of about 47 to 50 degrees (naturally, a higher maximum angle will allow a smaller turning circle).
What is the angle of a torsion axle?
What are the common starting angles available for torsion axles? The common angles are 45° down, 22.5° down, 0°, 10° up, and 22.5° up. 0° starting angle: The center of the spindle is on the same horizontal plane as the center of the axle beam.
How do you bend axles?
Using your 3/32″ hex key, loosen the set screw in the spring collar and slide it to the mark for the desired degree of bend and tighten. Place your thumb on the knob and pull the lever smoothly and steady with your index finger until the spring fully compresses to bend the axle.
How do you tell if you bend an axle?
Four Common Symptoms of a Broken Axle Shaft
- Wobble or Vibration. When you’ve bent or broken an axle shaft, like the one shown above, one of the first signs you’ll notice is a slight wobble at lower speeds.
- Visible Misalignment In The Tires.
- Sensitive Brakes.
- Leakage…
- At V&F.
How do you bend a derby axle without a bender?
Lay the axle into the indention you’ve made, with the alignment mark at the 12 o’ clock position. Clamp it with the pliers at the edge of the wood. Place your other hand over the one holding the pliers and apply gentle, steady downward pressure. Less is more, and it’s better to underbend than over.
Should I glue pinewood derby axles?
7. Create Glue Holes: Glue the axles firmly in their holes to ensure that they stay perfectly placed, but make sure you don’t get glue on your wheels. 8. Add Weight: Remember to make your Pinewood Derby car as heavy as the rules allow.
Is it better to have more weight in front or back of pinewood derby?
PUT MOST OF THE WEIGHT IN THE BACK
Science says the heaviest part of your car should be about 1 inch in front of the rear axle. The idea is that the farther back the weight is, the more potential energy you have because your center of mass is higher up on the track.
What is the fastest pinewood derby Shape?
But aerodynamics rule the day, and the best shape is a simple wedge. Just like a spoiler on the rear of a sports car, the wedge shape allows as much air to flow over the top of the car without hinderance while keeping the car pinned to the track.
How do you bend 1x wood?
Bending Wood with Water. Another method for bending wood involves soaking it in hot water until it becomes pliable. Once pliable, you’ll be able to clamp it to a form and allow it to dry. When it’s cool and dry, it will take the curved shape of the form.
Can you bend an axle?
They, along with the transmission, take the power from the engine and transfer it to the wheels. They are built to last but can be bent or broken if you run over a curb, hit a pothole at high speeds, or are involved in an auto collision.
What are CV angles?
Constant-velocity joints (also known as homokinetic or CV joints) are mechanical joints which allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly used in front-wheel drive vehicles.
How much angle can a CV joint take?
A CV joint may operate efficiently up to 80° deviation from a straight line. By operating in pairs, larger angles are possible.
Are torsion axles supposed to be bent?
Are Axles Supposed to Bend? In short, yes. The “bend” in an axle is called the Camber. (This is not to be confused with V-Bend; the small downward bend in the axle’s center.
Why are torsion axles better?
Torsion axles are mounted directly to the frame which means fewer moving parts compared to spring suspensions, resulting in a smoother shock action. This stiffens the frame, reducing flex. This system is also less likely to corrode because the axle tube is galvanized inside and out.
What is the free angle for a torsion spring?
25 ending such as 4.25 coils the free position is of a 90º (degree) angle. This is because when a spring has a solid number of coils without a fraction of coils such as 2, 3, or 4, etc. the tips where the coil terminate meet at the top of this spring.
What are the 4 types of bend?
There are generally four (4) different methods of tube/pipe bending that can also be classified according to complexity. You’ll encounter the following: compression bending, rotary draw bending, roll bending, and mandrel tube bending.
What is the correct speed for a bend?
You should be driving at a constant speed towards the bend. A good rule of thumb is that, after the gear change, there should be at least 2 seconds between your hand returning to the steering wheel and your turning of the steering wheel to steer through the bend.
Can you bend an axle by hitting a curb?
Beyond the wheels and tires, the hub, axle, steering arms, shocks, struts, and other suspension components can be bent or broken by a curb hit.
