Nice wheel getterdone.

If I were you I would move it outside and give it one circumference clearance with the ground. I would then tape a coat hook onto the wheel and loop a string onto the hook. Then I would wrap the string once around the wheel. On the loose end of the string I would fix a baseball. Spin the wheel in the opposite direction of the wrap and release the ball. You should send the ball 50 to 100 meters. By taping mass to the ball you should be able to get the wheel to just stop as the ball and tether release.

Newton’s Three Laws of Motion predict that the ball will have more energy than the wheel. There is nothing mysterious about it; it is simply Newtonian Physics.

Thanks Pequaide

If the wheel wasn't 3 ft taller than the shop door I might take you up on it.

I've been playing with springs lately, I'm trying to something similar to MT27 , I was thinking about Besslers reference to the runners leg. I'll post some more pics if I ever get the time to find the right combo of weights ,levers , spring stretch, and heavy perimeter .

I hit the button on my overhead door and pulled out my rolling 8 foot frame. I used my 18 inch rim to fire a 70 gram BB bag into a pine tree 10 meter to the rear (by mistake), about 3 meters up in the tree. It was a beautiful a line drive. I probably would not have caught the flight of the bag but I saw the pine tree shaking.

The bag hung up in the tree so I grabbed a tethered baseball; I have gobs of these tethered masses laying around. And I had decided to have some fun.

I first bounced the baseball off the ground about four meters to the front. Then I adjusted my release angle and it wound up in the tree, level with the 70 gram bag, and about a foot away. Well that is two in the tree.

Then I grabbed a weighted golf ball. The tether was way too long; it would roll the rim backwards before it threw. And it back fired into the pine and knocked down the 70 gram bag; and I also found the golf ball in the woods. The pine tree had stopped it's forward motion and it was laying on top of 4 inches of leaves. Two bits of luck; I got the bag back and I found the golf ball.

I adjusted the golf ball's tether and started throwing into another pine tree on the other edge of the lawn. That edge is 35 meters and beyond that is the tall grass prairie. You don't find things in the tall grass prairie.

I was being gentle with my throws because I knew that none of the masses and tethers were adjusted to that wheel; but they would throw into the pines anyway. I guess we need to figure out how much energy is in my left wrist. I did use both hands for the 35 meter throws.

If you can figure a way to reassemble that wheel of yours in the yard; I am sure you will have a lot of fun. You will have entered the world of the trebist.

That doe's look like fun, and if I ever get the wheel out of the shop, I might decide to fling a few been bags at the neighbors son who has a loud dirt bike.

I'll have to carry on with my experiments when I return in a month. I've set up a lever and weight meccanism on a type of homemade clutch. The weight fall, stretches the spring, the clutch locks, and the spring pulls the wheel, although I'm not getting OU, I think I'll keep persuing this path. I know that you only get back what you put into a spring, but the second and third bounce seem to give me a little bit extra for free.

I'll post some pics when I've had more time to improve on this design, it still kinda rough looking

....and the madness continues. I've been building some levers, and modifying old levers for this build.

This picture shows the direction I'm going with this one. The grey levers hang on to the perimeter at 3 points. The fixed track on the axle lifts the grey lever off the perimeter, at the 6 o'clock position, using the small white wheels. As it turns, the long strait bars transfers some of the weight of the levers to the axle, at the 9 o'clock position. From the 9 to 12 o'clock positions, the lever assembly rolls up on the bigger black roller

I'm still working on posting the pics

[getterdone]

I think I got it

[getterdone]

nope

[murilo]

Caralho!!!
THIS is a building!
Congrats!!!
Great!

Nice composite.

[getterdone]

Thanks, it's about half done.
I thought I should post a pic in response to Trevor's post on another thread I'll post more pics when I get a chance to do more work on it.
I hope to prove with this wheel that it is possible to have one side heavier than the other with everything being the same distance from the axle

Quote from Trevor
''PM cannot be derived from throwing weights around a fixed point of rotation ( there lies madness ), but weights in a balanced state can be rotated as a single system quite easily.

It comes back to a motion wheel over a gravity wheel. ''




When it is complete, I'll post a video to show you guys how it functions

Hi Getterdone,

Are you sure I said that?

I am not a fan on swinging weights or CF, that is for sure! Hope you prove me wrong, good luck, A working wheel is needed ASAP!

I am now of the opinion that a out of balance wheel is possible, I have gone from half hearted to believer! this is due to my on going experiments,

With much respect Trevor

Edit, are you sure you are talking swinging weights, or are you talking falling levers and tapping the leverage to drive the wheel, if it is the later then I am known as a big fan of that!!!

[rasselasss]

First class build Getterdone.....i'll raise a glass to you on Robert "Burns Night" 25th january .....you put a lot of work into that....Good Luck..

[getterdone]

Oooops, that was a quote from Chris. I apologize, my mistake.

Anyhoo, what I'm trying to demonstrate is that by hanging on to the axle on the negative side, and letting it fall freely on the positive side , it's possible to get a mechanical advantage.

I'll post more pics as the wheel progresses.

Hi getterdone,

when the weight falls off the axle it should give the wheel a shunt, but only until the lever pivot reaches a certain high, then there will be a lot of work needed to make the reset, I will watch this thread with interest!!

I am sure that this wheel design will lead to more wheel designs that will only get better and better, so, "getterdone" and good luck.

With much respect Trevor

Yeah thanks, that was one of my quotes ;-)

I absolutely stand by it as well because , as I've said many many times recently, unbalance is a by-product of a balanced state ( equal force up & down ). Gravity is used to create linear motion in the act of balancing. That motion is translated Into a rotary output .

You can bank that as a fact ;-) do not question my logic :-)
