Working SMOT ramp from Tom Ferko ?

Hi,

Here is my oppinion about the force at the end of the first V track labled B.

The ring magnet does not easily run the second V because its starting point has a much shorter distance between the V track rails at that point.  Thats in comparison to the very wide distance between the rails at the start point A.  Force B is much greater than Force A.  Thats the so called sticky spot.

We assume that point B is a sticky spot because enough power to move it further down the rails from A to point C is not present.

The starting point from A through C needs to be built up or stacked with additional magnets just enough to overcome the tendancy of the ring magnet to ROLL BACK at point B.     --- OR --   Maybe the first track at point B can be elevated enough so that the ring magnet will DROP OFF its end to somewhere between point A through C which now is at a lower elevation.  That should leave the powerfull backward attracting force at point B behind it.    Tom

Probably I understood you wrong, but do you mean if you lower the magnets in the end of the V, the roll back will decrease?

Hi All,

This Staggered V track might work with heavy magnet track runners but I dont think light track runners will hold steady.  In this case there is never a point on the track where the WIDE ENDS of the V shape are directly apart from one another causing runner roll back.  We know it as a sticky spot or regauging point.  Take a look at the very first page of this forum and check out my working linear stagger track movie.

My illustrated stagger track if placed UNDER the runner magnet might workout as it did in the working linear track.  This is the exact track  seup I am bonding onto my drum right now.   Each square on the grid represents 1/2 inch.  My runner magnet is that large.  Red north.   Blue south.

Most important to remenber that only the centerpoint of the round ring magnet is contacting the track below it at any time.  As you look down on it it looks like all the magnetic surface is in contact with the track.   Not so.  The runner will pull in the noted direction without dead or sticky spots.


Hey guys,   The setup I showed you before slowed down considerably at about 3/4 revolution.  This setup is what I am placing on my drum right now.  Notice it is one large V shaped track but the magnets on the rails are STAGGERED  Starts at 2 inch spacing and ends with 6 inch spacing.   

Why stagger the track rail magnets illustrated by Xs?   Simply put look at the wide end of the V track now and you see no magnet directly opposite each other that will cause a dead, sticky, or regauging spot.  The runner should fly past that point easily.   After the wide track end passes maybe doubling up the first two track starter magnets will be the extra kick to keep the runner in motion??   We will see.

We all know the long V track works but concerns are raised about the sticky spot at the tracks end.   Track magnet staggering should put that concern to rest.

If this works I will be the first to show a movie of it.   Its a chore bonding the individual magnets all over the drums surface with accuracy.

At the wide end of this V track if its elevated enough the runner should be able to go uphill to its end then by its inertia it will drop of the track and fall a bit to start of the new track in front of it.   This idea is impossible in a rotary configuration.  Only linear.
