Here's one way to keep the arms from hitting. Probably hard to replicate with Knex.....

Hi,
 New here and I am building a wheel that I am losing faith in. But, I drew this up today and think it has possibilities. What do you think. I know it is hard to see and is sort of jumbled but it's all there.

@Jason,

How are you coming with your cad study? Any recommendations?

Regards, Larry 

I guess Jason has been busy. I hope that's a good sign. I've downloaded Phun and have been playing around with that. Not a very extensive help file so I've been feeling my way around. In Phun, I've got my design to go around up to 7 times and with a little more tweaking I hope I can keep it going.
Larry, how are you coming?
Regards,
Charlie

Hi guys..

Sorry for the late response.  I have played with GMAX,  and Google SketchUp for 3D work.. Google may be easier to use.  I have played with eMachineShop for 2D work.. I find eMachineShop to be the easiest yet.  I also use Vizimag for magnetic simulations and a SPICE simulator for electornics.  I haven't tried Phun.. I'll give it a try.

I don't have any drawings yet.. but I'll try to explain my idea.. I am thinking of a small 2 foot (60cm) wheel and using magnets for the weights.. north facing both ends and then having a magnet at the base to repel the magnet weight up.  I think that there is enough down force to break any magnetic wall.

I'd like to add:

www.emovendo.net  (magnets)

www.sdp-si.com (bearings and shafts)

Both of these websites are good and have typically lower prices.  K&Jmagnetics has more selection of magnets but they are generally only N42 and more expensive than emovendo (which only sells N48's and at a better cost bargin).

Can you save simulations with Phun or make movies with it?  If so could you post your simulation?  What are you using to make your drawings? - Thanks, Jason

I think Stefan just has a temporary fix for the site.. he still plans on moving it to a better host when he gets back from vacation.

First I would also like to thank Stefan for his efforts, I'm sure it was a lot harder than most of us realize.

I picked up the new door knob latches this pass weekend. I am halfway thru getting them installed. I have the main body, slides, weight boxes, levers, and main spindle working. Also, as I'm sure this will be a tweak fest, I will be using bungee cords instead of springs during the test phase. They should be easier to adjust and modify than springs. So maybe by Friday I'll have some info to report.

I am really looking forward to testing how much addition force is required to move the weights to the midpoint + 1".

Thanks, Jason and Charlie for the cad update. This may end up being more important than our physical testing.

@Jason and Charlie_V
Thanks for the additional resources.

@ alaskabobb
Welcome, Great that you are trying knew designs, but your drawing has me confused.

I just tried to load a Phun file for you guys but apparently you can't upload a .phn extension. I would strongly suggest using one of these modeling program to save a lot of trial and error. Unfortunately there is no 'save as' so I can't show you what I've done in another format.

Looking forward to your update Larry!
Best,
Charlie

Hi Larry,  Thanks for the welcome. I'll try to state in other words how it is supposed to work. Each inner wt. is 4LBS. Each outer is 3LBS. Weights are hooked together by cables and in some cases have to go over pulleys to pull each other in the right direction. The inner wts. are used to pull the outer wts to where they need to be. The inner wts are 4lbs but only pull 2lbs worth of pull on a  individual outer by use of a tension spring that takes 2lbs to stretch it out, so it only pulls 2lbs. then as the wheel turns another inner weight comes into play and pulls another 2lbs. Thus pulling the outer wt into a favorable position. There are times when there are slack lines. When I state "strait through",  I meant for instance, that a wt was pulling from arm 1 to arm 4. The large circled number is what I perceive to be the "leveraged" weight of that arm. I start the inner wt at 1lbs because it can't be at the center and thus has wt on the lever. The outer, I start at 4lbs,because it is just beyond half way up the arm. I realize that I probably don't have the math down on the leverage, but moving a weight out twice as far doubles its weight force. The two numbers with the "+" sign and an arrow to a weight is the numbers of the arm that the weight is acting on or being acted upon by. So picture a maze of cables or strings with extention (tension) springs in line and some pulleys to reverse the pull at some points. The total weight  on the falling side should be heavier than that of the rising side. So to pull a outer wt out(Say arm 1), it takes the inner wt on the arm directly across (arm 4) and the inner wt on the next trailing arm (arm 3), to lift it. The inner wt on arm 4, also lifts on the outer wt on arm 2. Now at the bottom of the rotation the outer weight needs to be pulled in and this done by the inner wts again but in different combinations  of inner wts than they were pulled out by. For instance, Arm 4's outer wt is pulled in by the inner wts on arms 1 and 2, so the arm strait across and the next arm leading it.  And so on.  Hope this helps. I don't have time to build it right now, but if someone wants to, and it works, I'd be inclined to share patent rights. Or they can just buildit and use it for themselves.   Alaskabobb

Hi Charlie,

If you zip the file, you will be able to attach.  Excited to see!

Thanks,
Jason

Here's the zipped file. You will need to download Phun first and extract this file to the 'scenes' subdirectory. Open Phun and under the file pulldown menu select 'load scene' and click on the file 'wheel' to open it.
Click on the 'drag' tool in the tools menu...the one that looks like a hand...then click the green arrow to start the animation.
With the mouse pointer you can drag the weights to rotate the assembly.
Remember that this is not finished....see if you can figure out what I need add... ;D
Regards,
Charlie

Running behind, didn't get to testing phase yet, so I just wanted to pass a pic of the build. I only have two bungee cords in the pic, they are at the midpoint to have tension at each end of the movement. I need to pick up some eyebolts for the bungee cords and I will add bungee cords on each side of the weight boxes. Then I will mount the whole unit on a outside piling and add the stops to release the latches and pull the levers.

Wow...nice job! Can't wait to see it in action.
