New Wheel Design

[Alexioco]

Greetings Alex

Ralph told me a carpenter's secret for center hole and more even cut wheel. First off take your wood and draw an exact cross for your four corners. Then drill the center hole at the x. Then I use a router and a guide to cut out the circle/wheel base.

I hope this helps, it has saved me some headaches. LOL

Seems good but, this is what I did: I got a big compass, tightend it up then drew the circle, it all went fine, the hold in the centre was made when I used the compass meaning that it must of been dead centre, i then tried some geometry in finding the centre, I did this with care, when i found the cenre, it was just off the point that the compass had made, I did the geometry correctly and I got to different results lol, so I decided to drill the hole according to the compass and not the geometry I did, once the hole was cut, I put in the axle (which fits just right) I let the wheel go and it rotated alittle meaning that the axle wasnt centre, I have no idea whats going on...

That is the exactly point in conservation. Conservation means no change. No change means no work.
If gravity was dynamic, however, like it increased and reduced all the time, it would do work, but that isn't the case in real life.
So bottom line; A conservative force like gravity cannot do work, are not capable to do work, and will never do work.

Hello LowQ,

Imagine a piece of of debris floating in outer space in close proximity to Earth. As the debris gets closer to Earth, Earth's gravity pulls on it more and more until it begins a terminal course towards Earth's surface. On its way down it hits Earth's atmosphere, bursting into a fireball, the energy being released from the extreme friction of the atmosphere aginst the falling object. It is gravity that is "powering through" this friction, causing solid rock to burst into flame. That's not work?

The sun has been called a gravity powered fusion reactor by scientist because its immense gravitational field causes a never ending chain reaction of hydrogen atoms fusing to become helium atoms. That's not work?

Think about the Earth's core where solid rock is turned into liuquid magma simply through gravitational pressure which builds to such a level that from time to time is enough energy to level mountains and create islands. That's not work?

Alex,

I've found that the best way to make a perfect circle with a perfectly located center hole is to cut it with a router and a circle jig. You basically take a piece of plywood about 36" long or so and a few inches wider than your router. At one end of your piece you make an on center hole big enough for your router to sit in. From that hole's center you measure in inch increments down the center of the piece until you come to the end of the other side of the piece. You then drill the holes where you marked them with a drill bit that is the size of the axle you're going to use for you designs. I labelled my inch increment holes for easy reference. These numbers reflect the radius of the circle you're going to cut. Now your circle jig is done and it's time to use it!

Depending on whether your bearing is mounted in your wheel or it's just the axle that passes through it you select a drill bit that corresponds to that size. Use that bit do drill a hole anywhere on the plywood that you're going to use to make your circles (allow enough room for you circle(s) to fit within the sheet of plywood). If you drilled a hole for your bearing size drop your bearing in the hole and grab your circle jig. Pass either your axle or a bolt of the same diameter through the circle jig rdius hole you desire then through the bearing you just place in the sheet of plywood. Put you router in the circle jig where there is a hole for it. Adjust the router so it's about halfway through the wood. Turn it on and push your router around in a perfect circle with a perfect center. Do another pass that goes all the way through the wood to finish it off.

Also, RE: getting supplies on Sunday: There's now Lowes or Home Depot in your town? They should be open on Sunday. No? I've found that THE BEST store for PMM parts (which is also open on Sundays) is Tractor Supply. Their hardware aisle has almost anything you could ever need for such a thing.

Good luck. I can't wait to see your results!

Alex, PM me a drawing if you want modeling help.

Will not disclose and send you the wm2d model directly

I am curious as you may have guessed

erickdt, thanks for that, thats very helpful, I shall save your post and study it so I can make little wheels, for me, thats the hard part, i could cut a few wheels out and save them for when I get a new idea or even for improving on my design if it works

Having said that, my wheel isnt to bad, well acutally its two wheels with the weights inbetween, maybe if I turn one wheel upside down and attach them, then they will be balanced?

If only I had those nails right now...
