What is it that you find "sounds interesting" about the presentations.

Have you ever presented a similar measurement process, here on the OU forum ?
             If so What measurements would you like to see ?
             If so will you describe for me, a precise set of measurement procedures which
             which would be adequate to hold your attention ?

What tolerances would you consider as adequate and why ?

This is quite obvious, that the interesting part is the ability to turn off  magnetic attraction
(or repulsion) using above mentioned shields.
For example, magnets can produce tremendous output working in one direction, but require the same input to return them into the initial position.
If this input is illuminated using shields, than the problem is resolved.
The simplest would be to compare the effort of inserting and removing the shield with the
work produced by the attraction ( or repulsion).
Since you already have the apparatus in place, this shouldn't be that big of a task.
In order to provide the procedure, I would need to take a closer look at your setup
( but  by no means I consider myself a bigger expert than you in this field, or perhaps another member of this forum).
In terms of the tolerances, they should be within the reasonable precision of the
measuring instrument at hand - I hope that the difference between the input and output
can be easily detected.

I'm not an expert, just a learner.

The test bench is knocked down (its modular) pretty easy to set up though.
I'll need to  calibrate  and  level it.
I will also need to fill with water / calibrate my weight sets (bottles).
Before any of this I need to clear my work bench / shop   of other project remnants.

I don't have access to the triple beam balance I used to use, but I have a high precision, reliable, digital scales in its place.

The test bed does not have a cross sliding unit.  Consequently I can only do the measurements
by repositioning the magnet sets.  This works fine, just takes a little effort.... and labeling the magnets
so that the same magnets are in their original positions as shield,  stator and sliding magnets respectively.


I'll post once I'm set up.

This looks very good, but ideally your shield magnets should be as thin as possible,
as you've mentioned in the video.
In addition, you can use a variable diameter cams to compensate for non
linear force distribution, I believe you wrote about this option before.
But this will take much more work.
Looking forward for the results.

Up date......

I have had house guests, am bogged down with some other tasks right now and hardly spending any time on line.

Please be patient, I have some other measurement sets that are also motivating me toward getting the test bench set back up.


   thanks for your inquiries / suggestions

                     I will respond  as soon as I have something to respond with.
