@LarryC

 I looked at what you have done. The arm impact to make the shift will cause you a severe shake/jar and tear it apart even if you get it running, it won't run long. I have already played with this concept last year with counter weights and I understand the jarring that you are going to be effected with plus the CF problem. If you have any questions pleas ask in an email due to over exposure. ab.hammer@yahoo.com

Thanks Ab, for the confirmation.

Did realize that after I digested the warping problem. Along with the heavier hardware, I have also designed a gradient cam guide that will start off gradually and increase the rise rate as it approaches midpoint + 1". Much more tweaking!

 You are going to need much better construction as well. Try screen door roller bearings and 1/4 inch round stock steel for your track, and stronger bolts like carage bolts ect.

Good luck, you are getting close. P.S. you do know what my statement means?

You must have missed my previous post, had picked up sliding glass door roller bearings and 1/2 " angle iron for track.

OOPs post #357 LOL

I prefer round bar stock the rollers with the 1/2 round track fit them perfectly. less friction.

I really want to help out with some wm2d sims but I don't understand the design. NS's drawings don't make much sense to me.

Hi Broli,

First if you haven't look at the pic in reply #286, please check it out as we are trying to build a much lighter version of that unit.
The springs and belows are compressed when the two connected weights are brought to mid-point + 1" and then the spinning unit slams the weights into them and locked. The compressed centrifugal forces are used to help the movement from the bottom to mid-point + 1" in the next power cycle.

Since my unit is down, I did a Knex version to show you the mechanical movements. It does not have the bungee cords or actual locks as in the pics in reply  #353. The black tape is the weights.

It is going counterclockwise so the first pic is at 8. The stop on the bottom left is to release the latch holding the compressed forces and the stop on the bottom right starts to pull the lever.

The pic at 6 shows the weights have moved past mid-point + 1" and starting to slide upwards. The lever has slid past the stop on the right.

The pic at 5 shows the weights have slammed to the top and should have locked down the compressed forces.


Now, my design is being changed because a more graduated approach is needed to lifting the weights. That is why the slide warped. So a slower lifting cam will be needed at the beginning and maybe the lever after or just all graduated cam.

So, you can wm2d using the length specs that I gave to Charlie, but the real unknown is how much compressed centrifugal force is needed to get the weights back to mid-point + 1". Can wm2d simulate the gravity, centripetal and centrifugal forces at work? If you can simulate that it would really help!

Regards, Larry

I hope you aren't referring to some of my drawings in my older posts??? I think we have pretty much settled on trying to duplicate Bob Kostoff's design as close as we can with the limited info that we have. His is the only one that appears to work. WM2D would be great and is a much better program than Phun. I wish I had a copy.
Anyway, your help would be greatly appreciated.
Best,
Charlie

I always have big difficulties understanding other people's ideas for some reason. I still don't fully get the idea behind this design.

Are you trying to compress the spring more by the centrifugal force? And using this extra energy to push the weight back past their locking mechanism?

@ Broli,

Are you trying to compress the spring more by the centrifugal force? Yes! you got it.
Just like if you could save the slinging energy here http://en.wikipedia.org/wiki/Trebuchet to help with the next throw.

And using this extra energy to push the weight back past their locking mechanism? Not exactly sure what you meant here, but the locking mechanism is released and the compressed forces help to push the weights back to mid-point + 1".

Regards, Larry

I'm glad to see this project continues!  I haven't started with a build yet, but I like to see others progress.. when I start with mine I'll post my progress.  I'll continue to watch this thread.  Thanks for the updates and thank you Broli for any simulations you do.

Sounds simlar in thought to the egyptian fulcrum and what was trying to be accomplished with it by Archer Quinn one of the less favorite board members I know but he did sure put in a load of effort into that gizgantic thing anyhow neither here nor there just trying to point out the design may contain some obvious flaws pointed out by pure power or what have you I guess I dont see how this machine would work either not to discount its work as I've seen some interesting youtube video of this device a couple years ago I believe...

I am curious where the gimmick is that makes it all come together and work...

I'd love for gravity power to work but untill someone shares with us a working design I think I may piss into the wind and piss with it as well seems wind power may actually be worlds cheaper then other applications and we know it works but please dont give up on gravity some how some way there is a way to harness its power however for most time is of the essence we do not grow any younger.

There's really only one thing that bothers me (well, other than the fact that Uncle Bob has disappeared  ;))...and it just dawned on me this morning.
In order for this machine to work, something, somewhere has to be stationary. I just went back and reviewed the video for the umteenth time and can't seem to find it. For instance, take LarryC's Knex example. He has a stop to activate the release of the door knob latch mechanism and another stop to activate the lifting arm.
Bob mentions a cam lifting the weights initially. Now, I'm definitely not a Mechanical Engineer but I think there are only 2 ways that a cam would work in this situation (someone please correct me if I'm wrong). First, the cam itself would have to rotate faster than a cam follower fastened to the weights effecting the lift or second, the cam is stationary and the cam follower(s) rotate around the cam. In the video, and its certainly hard to see, it just appears that everthing is rotating. Unless there is something on the floor that is fixed and is hidden by the table in the foreground I'm missing the fixed parts of this machine.
Any help?
Thanks,
Charlie

I'm guessing also, but thought it was fixed to the table ???

My new cam guide will be fixed in the latch release area and a roller bearing follower on the bottom weight box. Think of the cam guide as a partial ellipse (slow rise to high rise)  that the weight box will follow up.

Did notice is his pic of the machine in #286 that the table is offset to the right of the arm. Probably to balance the forces create by the clockwise rotation. Lot of iron bar underneath(levers?) and what is that round object (part of cam?) to the right of the rotor on the table?

Interesting concept. Let us know how it works out. [edit] Do you think it might work better with a follower and cam guide on the upper weight box? It would seem that you would have more leverage....just a thought.

I could be wrong but the round object could be part of the drive gearing for his generator? Small gear on the shaft to a much larger one to ramp up the rpms?
