Q:Wheel tread after quenching hardness of HB600 above, there will be crack at the clean, welding insulation for 12 hours or so, repair welding and then around the cracks and repair the local hardness reduction (HB230 less than)! wheel material is cast steel used in ordinary welding wire

Welding should be divided into several times the welding, each welding with a pointed hammer gently tapping the solder joints to eliminate the weld stress, to be welded after welding to continue welding. This can minimize the impact of heat on other parts of the hardness of welding. In addition, the use of high-carbon electrode.

Q:I have 53mm wheels 99a. The roads where I live are quite bad. I can‘t seem to get much speed. I‘m looking for a smoother ride. Anybody recommend a good wheel?

Larger, softer wheels will do the trick. Your current wheels are small and fairly hard. Don't go smaller than 65mm and harder than 80a

Q:Hi, I just got my new skateboard this morning, and I think my wheels are too bigis that ok?Thanks

probably not they can rub on the bottom of the board and cause you to fall try some risers

Q:Hi I‘m looking for a decent pottery wheel. I don‘t know what would be better- eletric or pump.Anyways, I want to know if there is a certain brand or where I can get it like at Michaels or something. My budget if preffered 60$ and under.Thanks!

12.5 Thats assuming a 1500 watt iron (seems standard after doing a quick internet search) Amps power / volts This is also assuming a 120 Vac system. If the iron is in Europe, they typically use 240 Vac, so the current would be half, or about 6.25 amps.

Q:Why was the wheel a great invention?

There are basically three types of friction : *Static friction *Kinetic friction *Rolling friction Friction is a force which opposes the motion of the object. Among all the above kinds of frictions - Rolling friction is said to be the lowest. For example, take a case where you need to move a heavy gas cylinder. You can either make it move to pushing or pulling it, here kinetic friction plays a major role, thus it would be difficult to make it move a large distance. But in the other case, keep the cylinder horizontal and start rolling it. Here he cylinder moves much faster and your total work done would be less ( less force needed ). The particles in contact to the ground during a rolling motion are very less as compared to pure linear motion. This is main reason why the invention of wheels is considered as a great invention. You can travel more by applying very less force.

Q:Introduce the wheel galaxy

The Cartwheel Galaxy (ESO 350-40) is a lenticular galaxy located in the feathered seat, 500 million light years away from the Earth, and its diameter is about 150,000 light years.

Q:Hi everyone. Let me thank you even before I begin for all the answers you guys will be providing.I have a Mazda6 2004. I notice that the steering wheel has a little play. Its not huge and its felt more when I turn the steering wheel while the car is stationary. What could be the cause of this? I kind of sense that the play is right behind the wheel itself. That is, its not down the rod or anything. Can this be a simple fix?

Steering Wheel Play The most common of all problems in a steering system is excessive steering wheel play. Steering wheel play is normally caused by worn ball sockets, worn idler arm, or too much clearance in the steering gearbox. Typically, you shou Id not be able to turn the steering wheel more than 1 1/ 2 inches without causing the front wheels to move. If the steering wheel rotates excessively, a serious steering problem exists. An effective way to check for play in the steering linkage or rack-and-pinion mechanism is by the dry-park test. With the full weight of the vehicle on the front wheels, have someone move the steering wheel from side to side while you examine the steering system for looseness. Start your inspection at the steering column shaft and work your way to the tie-rod ends. Ensure that the movement of one component causes an equal amount of movement of the adjoining component. Watch for ball studs that wiggle in their sockets. With a rack-and-pinion steering system, squeeze the rubber boots and feel the inner tie rod to detect wear. If the tie rod moves sideways in relation to the rack, the socket is worn and should be replaced. Another way of inspecting the steering system involves moving the steering components and front wheel BY HAND. With the steering wheel locked, raise the vehicle and place it on jack stands. Then force the front wheels right and left while checking for component looseness.

Q:We are collecting redline hotwheels for our new born son. Do the hot wheels with the shiny read around the wheels count as redlines? Will hot wheels even be valuable from the 2000s? Thank you

Definitely, if the wheels have a red line around them (as the racing cars used to), they are redlines.The early years of Hot Wheels are known as the Redline Era as until 1977 the wheels had a red line etched around the tire rim, popular on muscle cars at the time." Hot Wheels from the 2000s are not valuable now, but who knows. I bet in the 1970s they didn't think they would be valuable in 30 years either. If you're serious about collecting, buy two, one to play, one to save! NOTE: In 1993 Hot Wheels issued replica versions of their redline series. They are currently about 5 dollars each, much less expensive than the old ones: amzn.to/lcQ1v1

Q:I‘m building a tricycle that will have rear-wheel traction, fed to the wheels via an axle.Planning to remove the bearing parts, yet the wheel axle will still be smooth on the inside. How do I get the axle to bite in order for the wheels to rotate with no loss of energy?Thanks

First, keep in mind that only ONE wheel should have power to it or when you turn the outside wheel will skid around and might make you lose control. If you are planning to use a standard wheel for the drive wheel, take the bearings out then tighten the cones right into the hub body. REALLY tight. Add a locknut on both ends of the axle. The next question is, how are you planning to drive that wheel without a LONG axle that extends to the chainline? Were it me doing this I would use a piece of 3/4 diameter (19mm) heavy gauge tubing and have it welded to the hub, then work out a differential that houses the bearings at both ends. Unless you are very good at this type of thing I am afraid you'll discover that it would be cheaper to buy a ready-made trike. I just thought of something that would be really cool. how about modelling a big bike after a kiddies bike- with pedals on the front wheel? That would solve all your problems- just make crank arms that'll fit the front wheel and also act as the axle.

Q:He use to be on his wheel alot but now he is never on it! :(
