Howard Johnson Replication Tube Claim

Let me just say I am having trouble with superglue.  Its probably due to the inexact shape of my pan.  I'm not getting an exact circle or something so the magnets are getting just a little too close.  Maybe also properties of the glue isn't quite a strong enough bond between the two smooth metals.  All I know is, BANG!  crap have to glue another rotor down...

5 minute epoxy might work? Or maybe a liquid weld product, home depot carries it.

Chet:

I have a small device my Dad made at Bell Labs that is nothing more than a toroid winding in a neat little box with a hole in it and an ac cord attached.  So, you stick any screwdriver into the box, hit the momentary push button for a few seconds and....poof....the screwdriver is now magnetized.  I have some that were magnetized with this device 30 years ago that still pick up and hold screws just fine.  This was with 110 ac house power.  He is gone now but I still have this device.  It showed me it is not that hard to permanently magnetize something.

Been trying out some different stators and field orientations with my disk today.
Just uploaded the first video .. will probably get a couple more hours in today.

Not sure how the jerkiness got into the youtube version  .. it's very smooth in the original file ? ? ..
seems to have appeared in the online version after Youtube processed it. 

i filmed it in 640 480 30 fps ..
Anyway .. guess i'll find out soon enough if my disk win spin like his.

It's here on Youtube ..

@queue, been watching the vid a second time. You're doing a great job. May I ask you instead of starting the rotor from standstill, to have the front of the 3m-30-3m-60-3m-30-3m set of mag clusters approach the stator magnet from afar (beyond a point where a stator-rotor interaction is felt) by making the rotor spin manually at the same rate as its rate when the mag cluster exits the stator magnet. Thanks.

Uploaded a last video for today @ Youtube just now ..

i finished placing magnets just now .. fingers covered in crazy glue ..argg
did some preliminary testing with two different stators and somewhat dismayed to say that
my disk does not seem like it wants to keep on turnin on it's own.

Like all SMOTS i ever played with they stop moving once you try and close the loop.

This one completed the rotor array after each addition of the next array segment or magnets - i tested after each one
but the disk was always moving more slowly -- the more magnets i added.

Once i closed the loop by adding the last set of mags  - almost no more movement @ all.

Will film that tomorrow. I think maybe i didn't place the magnets closely enough to Mylows config .
i thought i had calculated it correctly alas .. i think maybe miscalculated somewhere @#$@# 

My disk is exactly 18 inches - my magnets are 10 millimeters width.
Someone want to take a crack at it ?
Been working on this all day .. to much coffee .. need to get some sleep .. work tomorrow.

TGIF
More tomorrow .. hopefully some more positive results.

Cheers
