It Would Be More Noble To Clear J. Bessler's Name, than trying to solely profit

This is my workshop after a recent new paint job...

ROTFLMAO

I'm going to revisit the design that I thought of on 6 June.

May have been trying to make it go the wrong way.

It's the design where I was blowing off about so many pounds of sideways force measured on the perimeter.

[rks1878]

This design, going either way, I am not expert enough with WM2D to simulate.
Just as well...
I'm making a whole new mdf wheel and other wooden parts.
The wheel will be a little bigger this time.
Mounting everything to the oak support post helps a lot to keep the flying weights under tight control.

Are you aware that there is a 3D version of the tool, for which somebody on the board posted a link to the download location?

If interested and don't find it, I can try to search and post reference to that post...

amateur...

Are you saying that there is a free 3D version of WM2D available for download? If so, then I might like to check it out even though I've had some bad experiences with prior attempts to get into 3D modeling.

Yes thank you, I know of it, but 3D would be more difficult than 2D.
I don't really trust WM much anyway.
Have had a rash of working sims, but they're all nonsense in reality.

[rks1878]

Haven't had enough spare time to do more than disassemble the last wheel and reuse some parts so far.
Will use twelve weights. Did set one free to move with eleven just screwed on, however.
Really busy in the cabinet shop, and back on a full time schedule (three 12 hour shifts), at the hospital, but will do what I can with the wheel.....

Spent some time improving how the new wheel spins. There is only an almost imperceptible amount of sideways wobble at the perimeter.

Geee...I wonder if this is the one!

I'm flooded with ideas and the means to carry them out!!

[rks1878]

Dilemma.......

So, how do I start?

Even number of levers, or odd?

Or half even and half odd?

I think I will do 3 at first. But, I'm sensing from what I see, three evenly spaced positions with the third occupied by a counterweight to the other two that move, may do it.


Really, if even, then two should go. If odd, then three should go. Just trying to reduce to the lowest common denominator........

Or, is it 4 and 6?

[rlortie]

Robert,

I have a hang up with using odd numbers as it deletes the canceling of the two at 12 and 6 when using an even number.

Also from my experience I am inclined to believe that when using an even number, any more than eight is adding extra friction and is of little value. My sweet spot is an odd of seven or nine.

Which reminds me. Can anyone give me that link to the web that shows you how two lay out a circle for diffrent number of sides. I lost it when my computer crashed, and can not remember what the name was.

Ralph,
Hope all is well with you.

Think I'll try three for starters.

Now need to drill holes in the weights on their sides so I can screw them to the ends of their holders. When they fall and impact, the round side will be gentler on the wooden anvils than a square flat edge woud be.

[ken_behrendt]

I've found that it really makes no difference whether one uses an even or odd number of weights in a design. With an even number, one always has the same number of weights on each side of a wheel at all times. With an odd number of weights, one has an even number on one side and an odd number on the other side of the wheel that merely exchange positions every 180° of wheel rotation.

Generally, I recommend using an even number of weights at all times like the 8 that Bessler used to drive his wheels. Then figure out a way to temporarily imbalance this arrangement to create a torque in one direction only.

Ken,

Sorry to disagree with you but an odd number of weights does not change in every 180 degrees. It changes every 360 divided by number of weights, for nine that is 40 degrees.

Nine also happens to be the sweet spot for number of pistons on a radial internal combustion airplane engine as it negates the torque that would cause resinate torque from building in the airplanes fuselage.

I have reason to believe that Bessler may have used nine weights but every 40 degrees one becomes static. And that is why you get the sound of eight per revolution. It also creates the imbalance you speak of.

I am presently building such a wheel on the fly at present. Must admit that I can not live up to my WM2D schedule of two days. I am afraid that it is going to take a little longer.

Oh well guys, it doesn't matter. I'll start with three and if that doesn't work, go on up to 12, adding one at a time.

Have to work at the hospital thru, fri and sat, so will get to it next week.

Am now building a walnut distribution box for a school, with qtr columns on the front corners and an access door on the side. Pretty large,,,,,24w x 12d x 48h so have to work on that tomorrow (because I'm late with it and school has already begun!).
